Xynph FTP Server is a shareware FTP server available for Microsoft Windows operating systems. A problem in Xynph FTP Server may allow a remote user to gain access to unauthorized resources. A problem with the handling of input has been reported in Xynph FTP Server. Under some circumstances, it may be possible for a remote user to escape the FTP root directory using relative path notation. This could allow unauthorized access to systems using the vulnerable software. It should be noted that this problem may allow an attacker to download arbitrary files on the vulnerable system. Additionally, the attacker would be able to access any files on the system to which the FTP server has access rights, which may be run with SYSTEM privileges in some configurations.
2. BitMover BitKeeper Daemon Mode Remote Command Execution Vulnerability
BugTraq ID: 6588
BitKeeper is a source code management system by BitMover. It is available for Unix, Linux, and Microsoft Windows operating systems. A problem with BitKeeper may make remote command execution possible. It has been reported that BitKeeper is vulnerable to an input validation bug. When the software is run in daemon mode, it starts a service with an interface that can be connected to via HTTP. By sending specially crafted input to the service, it is possible to execute abitrary commands. The program does not properly filter single quotes. As a result, commands contained between quotes will be executed on the host running the vulnerable software. Any commands executed between quotes will be executed with the privileges of the BitKeeper daemon process.
3. BitMover BitKeeper Local Temporary File Race Condition Vulnerability
BugTraq ID: 6589
BitKeeper is a source code management system by BitMover. It is available for Unix, Linux, and Microsoft Windows operating systems. A problem with BitKeeper may make local symbolic link attacks possible. It has been reported that BitKeeper is vulnerable to a race condition error. Under some circumstances, BitKeeper creates files in the temporary directory. However, it may be possible to create a symbolic link in a crucial point of program execution that would result in the overwriting of files at the end of the link. The program does not properly open the temporary file. Rather than performing the check and opening the file all in one function, the program first checks, then in a seperate function opens the file. This creates a window of attack that could result in the overwriting of files that are write-accessible to the BitKeeper process.
4. BitMover BitKeeper Local Insecure Temporary File Permissions Vulnerability
BugTraq ID: 6590
BitKeeper is a source code management system by BitMover. It is available for Unix, Linux, and Microsoft Windows operating systems. A problem with BitKeeper may make the destruction or injection of information possible. It has been reported that BitKeeper insecurely creates temporary files. Under some circumstances, BitKeeper creates files in the temporary directory. However, these files are created with world-writable permissions, which may allow the removal of these files, or injection of data into them.
5. YABB SE Reminder.PHP SQL Injection Vulnerability
BugTraq ID: 6591
YaBB SE is a freely available, open source port of Yet Another Bulletin Board (YaBB). It is available for Unix, Linux, and Microsoft Operating Systems. A problem with YaBB SE could make it possible for a remote user launch SQL injection attacks. It has been reported that a problem exists in the Reminder.php script distributed as part of YaBB SE. Due to insufficient sanitizing of input, it is possible for a remote user to inject arbitrary SQL into the database used by YaBB SE that could be used to reset or change the password of a user. This problem may allow a remote user to change the password of the administrative user of an instance of YaBB SE. It may also allow a remote user to gain other information from SQL databases used to backend YaBB SE.
6. Stunnel Unspecified SIGCHLD Signal Handler Vulnerability
BugTraq ID: 6592

This vulnerability has been reported to affect Stunnel versions prior to 4.04.
7. phpPass AccessControl.PHP SQL Injection Vulnerability
BugTraq ID: 6594
phpPass is a system that allows restrictions to web pages. It is implemented in PHP and is available for a variety of platforms. A problem with phpPass may allow an attacker to launch a SQL injection attack. The vulnerability exists in the accesscontrol.php script included with phpPass. Due to insufficient sanitization of user-supplied input, it is possible for a remote user to inject arbitrary SQL into the database used by a vulnerable site. This may allow an attacker to view pages that would normally be restricted. SQL injection attacks may also potentially be used to exploit latent vulnerabilities in the underlying database implementation. This vulnerability was reported for phpPass 2. It is not known whether other versions are affected.
8. W-Agora Remote File Disclosure Vulnerability
BugTraq ID: 6595
W-Agora is a freely available, open source PHP forum software package. It is available for Unix and Linux systems. A file disclosure vulnerability has been reported for W-Agora. Reportedly, some scripts included with W-Agora do not adequately sanitize some user-supplied input. The vulnerability was reported to exist in the index.php and modules.php script files. An attacker can construct a URL consisting of dot-dot-slash (../) character sequences to obtain access to files outside of the document root. It should be noted that only files accessible by the web server will be disclosed to the attacker. Exploitation of this vulnerability may lead to disclosure of sensitive information that may be useful in mounting further attacks on the host system. This vulnerability affects W-Agora 4.1.5.
9. mpg123 Invalid MP3 Header Memory Corruption Vulnerability
BugTraq ID: 6593
mpg123 is a MPEG audio player for Linux variant operating systems. A memory corruption vulnerability has been reported for mpg123 that may result in code execution. The vulnerability exists when mpg123 is used to play certain MP3 files. Specifically, when playing MP3 files with malformed or overly large headers, it may be possible to cause mpg123 to execute malicious attacker-supplied code. The file common.c defines MAX_INPUT_FRAMESIZE to a value of 1920 bytes. An attacker can exploit this vulnerability by creating a malicious MP3 file that contains headers consisting of greater than 1920 bytes. When mpg123 is used to play this corrupted MP3 file, it will trigger the buffer overflow condition. Any attacker supplied code will be executed with the privileges of the mpg123 process. This vulnerability has been reported to affect mpg123pre0.59s.
A vulnerability has been discovered in Cyboards PHP Lite. Due to
insufficient sanitization of user-supplied variables by the
By placing a script on an attacker-controlled host and mimicking the name and directory structure of the server, it is possible to cause a vulnerable server to include the file. It may be possible to exploit this issue to execute arbitrary commands with the privileges of the target server.
Multiple cross site scripting vulnerabilities have been discovered in Cyboards PHP Lite. These issues occur due to insufficient validation of user supplied values. It is possible for a remote attacker to create a malicious link containing script code that will be executed in the browser of a legitimate user. All code will be executed within the context of the website running Cyboards PHP Lite. This issue affects the following PHP scripts: include/default_header.php include/options_form.php adminopts/login_form.php adminopts/include/ban_form.php adminopts/include/board_form.php adminopts/include/login_form.php adminopts/include/vip_form.php This issue could be exploited to steal a legitimate users cookie-based authentication credentials. Information gained in this manner could be later used to hijack a legitimate users web session.
UUCP is the Unix-to-Unix Copy Protocol infrastructure, implmented with numerous Unix and Unix clone operating systems. A vulnerability has been discovered in the Solaris implementation of UUCP. The problem is due to insufficient bounds checking of user-supplied filenames. By passing excessive data as an argument for the '-s' command line parameter it is possible to trigger a buffer overflow. By exploiting this issue to overwrite sensitive locations in memory, it may be possible for an attacker to execute arbitrary code. As UUCP is installed setuid root this would result in the execution of attacker-supplied commands with the privileges of the superuser.
Symantec Norton Internet Security is a suite of commercial security utilities including Norton Personal Firewall and Norton Antivirus. Symantec Norton Internet Security 2003 is reported to be prone to a denial of service condition. It is possible to trigger this condition by sending an excessive (approximately 65500 or more) number of ICMP packets to a host running Norton Internet Security. This may cause a denial of service and possible system instability. For this issue to be present, the software must be configured to allow ICMP packets and the firewall must be enabled. It is not known if earlier versions of the software are also affected by this vulnerability.
Geeklog is freely available, open-source weblog software. It is written in PHP and will run on most Unix and Linux variants, as well as Microsoft Windows operating systems. The Geeklog 'profiles.php' script is prone to multiple cross-site scripting vulnerabilities. This issue is due to insufficient sanitization of input submitted in URI parameters. This input will be displayed in webpages generated by Geeklog. As a result, an attacker may create a malicious link to a site hosting Geeklog, which contains malicious HTML or script code. When such a link is visited by an unsuspecting user, attacker-supplied script code will be interpreted by their web client in the security context of the site hosting Geeklog. Exploitation of this issue may enable an attacker to steal cookie-based authentication credentials from legitimate users of the software. Other attacks are also possible.

Geeklog is freely available, open-source weblog software. It is written in PHP and will run on most Unix and Linux variants, as well as Microsoft Windows operating systems. Geeklog is prone to HTML injection attacks. The user account 'Homepage' field is not sufficiently sanitized of HTML and script code. As a result, a malicious user may inject malicious HTML and script code into this field when editing their user information. When the malicious user's account information is displayed to other web users, the attacker-supplied code will be interpreted in their web client in the security context of the site hosting the vulnerable software. Exploitation of this issue may enable an attacker to steal cookie-based authentication credentials from legitimate users of the software. Other attacks are also possible.
vAuthenticate is an authentication script that uses PHP and MySQL. It is available for the Microsoft Windows, Linux, and Unix operating systems. A vulnerability has been discovered in vAuthenticate. It has been reported that the 'auth.php' fails to sufficiently sanitize user-supplied variables, making various PHP files prone to SQL injection attacks. This may make it possible for an unauthorized to access protected documents. The 'chgpwd.php' and 'admin/index.php' scripts are affected by this issue. An attacker that is able to access protected web pages may gain sensitive information that may aid in launching further attacks against a target server. SQL injection attacks may also potentially be used to exploit latent vulnerabilities in the underlying database implementation. This vulnerability was reported for vAuthenticate 2.8.

20. Psunami Bulletin Board Psunami.CGI Remote Command Execution Vulnerability
BugTraq ID: 6607
Psunami is bulletin board software. It is implemented in Perl and is available for Unix and Linux variants. Psunami Bulletin Board is prone to a remote command execution vulnerability. This issue is present in the 'psunami.cgi' script. Psunami does not sufficiently sanitize shell metacharacters from query strings. Input supplied via the 'topic' URI parameter will be passed to a Perl open() call. As a result, it may be possible for a remote attacker to execute arbitrary commands in the context of the webserver process. A remote attacker may exploit this condition to gain local, interactive access to the underlying host.
21. D-Link DWL-900AP+ Firmware Upgrade Configuration Reset Vulnerability
BugTraq ID: 6609
The DWL-900AP+ is a wireless access point manufactured by D-Link which is capable of speeds up to 22Mbps. A vulnerability has been discovered in the DWL-900AP+. The D-Link AirPlus Access Point Manager is used for various adminstrative tasks including firmware upgrades. It has been reported that upgrading the DWL-900AP+ firmware with this software will cause all configuration settings to be reset to factory defaults. This poses as a security risk as an unknowing user may upgrade there device and leave their device accessible with a publically known adminstrator password.
22. HTML Forms Generation And Validation Forms.PHP HTML Injection Vulnerability
BugTraq ID: 6608
The HTML Forms Generation And Validation package is a freely available, open source PHP package. It is written and maintained by Manuel Lemos. A problem with HTML Forms Generation And Validation could make HTML injection attacks possible. It has been reported that the forms.php component of HTML Forms Generation And Validation does not properly check input. Because of this, an attacker could potentially launch HTML injection attacks indirectly via form fields. This may allow for malicious script code to be inadvertently executed in the browser of a user who views pages which include attacker-supplied HTML and script code.
23. Trend Micro OfficeScan CGI Directory Insufficient Permissions Vulnerability
BugTraq ID: 6616
Trend Micro OfficeScan is an enterprise-level centrally managed antivirus solution. A vulnerability has been reported for Trend Micro OfficeScan that may allow attackers to access programs residing in the cgi directory of the OfficeScan installation.
