2. The Canary in the Data Mine
At the turn of the century just past, mining companies would use a brightly colored bird in the mine shaft to protect the lives of citizens. These canaries were more sensitive to the foul, noxious and deadly but invisible vapors that would otherwise threaten the lives of the mine shaft workers. When the canaries died, the miners would know an invisible threat existed. http://online.securityfocus.com/columnists/136 3. SecurityFocus DPP Program Attention Universities!!

Blackboard Learning system is a suite of software products available for Microsoft Windows, Linux and Solaris servers that power an "e-Education Infrastructure" for education providers. Blackboard Learning System, in some cases, does not sufficiently sanitize user-supplied input which is used when constructing SQL queries. As a result, attackers may supply malicious parameters to manipulate the structure and logic of SQL queries. This may result in unauthorized operations being performed on the underlying database. This vulnerability was reported to exist in the search.pl script file (the address book search feature). A remote attacker can exploit this vulnerability to brute-force user accounts. It may also be possible to conduct other attacks, such as executing stored procedures and exploiting vulnerabilities in the database server. This vulnerability was reported for Blackboard Learning System 5.5.1,level 1 and 2. Previous releases may also be affected.
2. Microsoft Windows Locator Service Buffer Overflow Vulnerability
BugTraq ID: 6666
It has been reported that the Microsoft Windows Locator service is affected by a remotely exploitable buffer overflow vulnerability. The condition is due to a memory copy of RPC arguments received from remote clients into a local buffer. An attacker can exploit this vulnerability by constructing a remote procedure call that invokes Locator service with malformed parameters. When the Locator service receives this request, the malicious arguments will trigger the overflow condition. This vulnerability may be exploited by remote attackers to execute custom instructions on the target domain controller. It is also possible to crash the service with a malicious request. It should be noted that, to exploit this vulnerability, no authentication is required. Additionally, the Locator service is enabled by default on all Windows 2000 and Windows NT Domain Controllers (DC).
3. Microsoft Outlook 2002 V1 Exchange Server Security Certificate Information Leakage Vulnerability
BugTraq ID: 6667
Microsoft Outlook 2002 is a e-mail, calendaring, and scheduling application for Microsoft Windows. Microsoft Outlook 2002 supports various types of certificates to facilitate transport of encrypted e-mail via public key cryptography. One type of certificate supported by Microsoft Outlook 2002 is V1 Exchange Server Security certificates, which may be used in combination with a Microsoft Exchange server. There is a flaw in the Microsoft Outlook 2002 implementation of message encryption using V1 Exchange Server Security certificates. When configured to use this method, Outlook 2002 fails to correctly encrypt messages. As a result, messages are transferred in plaintext, visible to network eavesdroppers. Furthermore, the user may assume that the message was successfully encrypted. A remote adversary may potentially take advantage of this issue if they are in a position to intercept user mail or eavesdrop on network traffic between the client host sending the mail and hosts receiving or processing the mail. This issue is reported to occur when Outlook 2002 is used to send HTML e-mail using the certificate. It should also be noted that the implementation of digital signatures using V1 Exchange Server Security is not affected.
4. Nite Server FTPD File Disclosure Vulnerability
BugTraq ID: 6648
Nite Server is a FTP server for Microsoft Windows platforms. Nite Server is prone to a file disclosure vulnerability. User-supplied input is not sufficiently filtered from FTP commands. As a result, it is possible for remote FTP users to break out of the FTP root directory by issuing a 'cd' (change directory) request containing directory traversal sequences. Any system files which are readable by the FTP server may potentially be disclosed to a malicious FTP user who exploits this vulnerability. The FTP server will typically run with SYSTEM privileges on Windows. This issue was reported in Nite Server 1.83. Earlier versions may also be affected.
5. Sambar Server results.stm Cross Site Scripting Vulnerability
BugTraq ID: 6643
Sambar Server is a multi-threaded web server which will run on Microsoft Windows 9x/ME/NT/2000 operating systems. Sambar Server does not adequately filter some HTML code thus making it prone to cross-site scripting attacks. It is possible for a remote attacker to create a malicious link containing script code which will be executed in the browser of a legitimate user. An attacker can exploit this vulnerability by manipulating URI parameters in the results.stm page to include malicious HTML code. Any attacker-supplied code will be executed within the context of the website running Sambar Server. This issue may be exploited to steal cookie-based authentication credentials from legitimate users of the website running the vulnerable software. The attacker may hijack the session of the legitimate by using cookie-based authentication credentials. This vulnerability was reported for Sambar Server 5.3 and earlier.
6. Apache Web Server MS-DOS Device Name Denial Of Service Vulnerability
BugTraq ID: 6662
Apache is a freely available Web server for Unix and Linux variants, as well as Microsoft operating systems. A vulnerability has been reported in Apache Web server for Microsoft Windows 9x/Me operating environments. The vulnerability exists in the way some HTTP requests are handled by the Apache Web server. Specifically, HTTP requests that involve MS-DOS device names may cause the Apache Web server to crash.
An attacker can exploit this vulnerability by sending a malformed HTTP GET
request to the Apache server using a reserved MS-DOS device name such as
This vulnerability exists for Apache versions prior to 2.0.44 for Microsoft Windows 9x/Me operating environments.
7. Rediff Bol URL Handling Denial Of Service Vulnerability
BugTraq ID: 6670
Bol is a freely available chat client available from Rediff. It is available for Microsoft Windows operating systems. A problem could make it possible for remote user to deny service to legitimate users of the chat client. It has been reported that a problem in Rediff Bol may allow remote users to log other users out of the Bol chat client. Due to improper handling of some types of requests, a remote user could send an URL request to the client in the form of a rbol: command that would cause the client log out. Under ordinary circumstances, the chat client should not react input from untrusted users. This problem could make it possible for a remote user to launch a continuous denial of service against a user of the vulnerable client.
8. MyRoom save_item.php Arbitrary File Upload Vulnerability
BugTraq ID: 6644
MyRoom is an online item management system implemented in PHP. It is available for a variety of platforms including Linux variant operating systems and Microsoft Windows. A problem with MyRoom may make it possible for remote attackers to upload files to a vulnerable system. Due to inadequate security checks performed by some PHP scripts, an attacker is able to upload arbitrary files to the system. The room/save_item.php script has been reported to be vulnerable to this issue.
Specifically, the script only checks to see whether the file to be
uploaded is an image file. As such, any file that includes the allowed
extensions may be uploaded. Any uploaded files will be stored in the
Given the ability to upload arbitrary files to the host, an attacker can exploit this vulnerability to upload malicious applications to the vulnerable system or use the system for the storage of files. This vulnerability was reported for MyRoom 3.5 GOLD.
9. GlobalScape CuteFTP LIST Response Buffer Overflow Vulnerability
BugTraq ID: 6642
CuteFTP is a commercially available FTP client distributed by GlobalScape. It is available for the Microsoft Windows platform. A buffer overflow condition has been reported for the CuteFTP application. The vulnerability is due to insufficient bounds checking performed on certain FTP command responses. Specifically, CuteFTP does not adequately check the responses to a LIST command. An attacker can exploit this vulnerability by enticing a victim user to connect to an attacker-controlled FTP server. When the victim user sends a LIST command, the attacker-controlled server will respond with an overly long response, consisting of greater then 256 characters, to the vulnerable client. This will trigger the buffer overflow condition and will cause CuteFTP to behave unpredictably. Exploitation may result in the execution of malicious attacker-supplied code with the privileges of the CuteFTP client. This vulnerability was reported for CuteFTP 5.0 build 50.6.10.2.
CVS is the concurrent versioning system. CVS is a freely available, open source software development package for the Unix, Linux, and Microsoft Windows platforms. CVS is prone to a double free vulnerability in Directory requests. Malformed Directory requests may potentially cause dynamically allocated memory to be de-allocated twice, using the free() function. An attacker may potentially take advantage of this issue to cause heap memory to be corrupted with attacker-supplied values, which may result in execution of arbitrary code in the security context of the CVS server.
Apache is a freely available Web server for Unix and Linux variants, as well as Microsoft operating systems. A vulnerability has been reported in Apache Web server for Microsoft Windows 9x/Me operating environments. The vulnerability exists in the way some HTTP requests are handled by the Apache Web server. Specifically, the issue exists due to the way some CGI input is redirected when the ScriptAlias directive is enabled. The ScriptAlias directive is used to map between URLs and paths residing outside of the DocumentRoot. This directive also enables the target directory as containing only CGI scripts. An attacker can exploit this vulnerability by making a malformed HTTP POST request to 'con.xxx' in a directory enabled with ScriptAlias. When this malformed POST data is sent to a CGI, it may result in any malicious code to be executed by the requested CGI. This vulnerability exists for Apache versions prior to 2.0.44 for Microsoft Windows 9x/Me operating environments.
Apache is a freely available Web server for Unix and Linux variants, as well as Microsoft operating systems. A vulnerability has been reported in Apache Web server for Microsoft Windows operating environments. The vulnerability exists in the way some HTTP requests are handled by the Apache Server. Any HTTP requests that end in some illegal characters will cause the server to disclose the contents of certain files to a remote attacker. It has been reported that an HTTP request that ends in the '>' character will cause the Apache Web server to serve certain files to the remote attacker. Any information obtained in this manner may be used by the attacker to launch further attacks against a vulnerable system. This vulnerability exists for Apache versions prior to 2.0.44 for Microsoft Windows operating environments.
Apache is a freely available Web server for Unix and Linux variants, as well as Microsoft operating systems. A vulnerability has been reported in the Apache Web browser that may result in the server bypassing existing default mappings when serving files. The vulnerability exists when making requests for files in directories with extensions. The vulnerability may cause the Web server to incorrectly parse the requested file. An attacker may be able to make a request for www.target.com/folder.php/test. The request for the file test should be served as a text file but due to some flaws in the mapping algorithm, the file 'test' will be interpreted as a PHP script. This may have unintended consequences on users and the system. This vulnerability was reported to affect Apache versions prior to 2.0.44.
Microsoft Content Management Server (MCMS) 2001 is an Enterprise Server product used for developing and managing E-Commerce web sites. MCMS contains pre-defined ASP web pages which are used to update web sites. A vulnerability has been discovered in one of the pre-defined ASP pages included in MCMS. Due to insufficient sanitization of user-supplied data by the ASP page, MCMS may be prone to cross-site scripting attacks. The issue occurs when constructing a response page which relies on various user-supplied values. By constructing a malicious link an attacker may be able to trick an unsuspecting user into triggering this vulnerability. This could be used to steal a user's private information, such as cookie-based authentication credentials. Other attacks are also possible.
Shambala Server is a FTP, Web, and Chat server targeted for the Small Office/Home Office user. It has been designed for use with Microsoft Windows operating sytems. A denial of service vulnerability has been reported in the Shambala FTP server. Shambala reportedly crashes when a FTP user executes a 'CWD' (change working directory) command, specifying the root (/) directory. Successful exploitation will result in a denial of service. The service will need to be restarted to regain normal functionality. This vulnerability was reported to affect Shambala Server version 4.5. Earlier versions may also be affected.
YaBB SE is a freely available, open source port of Yet Another Bulletin Board (YaBB). It is available for a number of platforms include Unix, Linux, and Microsoft Windows operating systems. YaBB SE allows remote users to influence the location of an external script ('Packer.php') that is included by the 'Packages.php'. A remote attacker may exploit this condition to cause an external, attacker-supplied file to be included by YaBB SE. If the attacker includes malicious PHP code, then it may be executed. This may allow a remote attacker to execute arbitrary commands in the context of the webserver.
WinRAR is a compression utility capable of reading and writing files using several different archival formats. It is available for the Microsoft Windows Operating system. A vulnerability has been discovered in WinRAR. The problem occurs when displaying an archive in the ListView Control window. If a file in the archive contains a file extension of 256 bytes or more, a buffer in WinRAR will be overrun. This may allow an attacker to construct a malicious WinRAR archive designed to overwrite sensitive values in memory. It has been reported that it is possible for an attacker to exploit this issue to run arbitrary instructions. Commands executed in this manner would be run with the privileges of the vulnerable program.
Zorum is a freely available, open source PHP forum. It is available for UNIX, Linux, and Microsoft operating systems. A problem could make it possible for remote users to execute arbitrary commands. It has been reported that Zorum may allow remote users to influence to location of PHP includes. Because of this, it is possible for a remote user to include an external arbitrary PHP script containing commands that may be carried out on the vulnerable host. This problem could allow a remote attacker to execute arbitrary code with the privileges of the web server process. This could result the attacker gaining local access, and potentially elevated privileges.
It has been reported that Microsoft Windows 2000 Terminal Servers and XP Pro are prone to a denial of service due to a problem with 'MSGINA.DLL'. This condition may be triggered by users who can successfully login to the server via RDP or ICA. 'MSGINA.dll' is the vendor-supplied Graphical Identification and
If a malicious user causes a read-lock to be placed on
An attacker may trigger this condition by opening the dynamic-link library with an external application, such as a hex editor.
20. YaBB SE News.PHP Remote File Include Vulnerability
BugTraq ID: 6674
YaBB SE is a freely available, open source port of Yet Another Bulletin Board (YaBB). It is available for a number of platforms include Unix, Linux, and Microsoft Windows operating systems.
A vulnerability has been discovered in YaBB SE. Due to insufficient
sanitization of some user-supplied variables by the 'News.php' script, it
is possible for a remote attacker to include a malicious PHP file in a
URL.
An attacker may exploit this by supplying a path to a maliciously created
file, located on an attacker-controlled host as a value for the
If the remote file is a malicious PHP script, this may allow for execution of attacker-supplied PHP code with the privileges of the webserver. Successful exploitation may provide local access to the attacker. This vulnerability was reported for YaBB SE 1.5.1 and earlier. III. MICROSOFT FOCUS LIST SUMMARY
