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.
2. Geeklog Users.PHP Cross-Site Scripting Vulnerability
BugTraq ID: 6602
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 a cross-site scripting vulnerability in the
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.
3. Xynph FTP Server Relative Path Directory Traversal Vulnerability
BugTraq ID: 6587
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.
4. Geeklog Comment.PHP Cross-Site Scripting Vulnerability
BugTraq ID: 6603
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 a cross-site scripting vulnerability in the
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.
5. Geeklog Homepage User Field HTML Injection Vulnerability
BugTraq ID: 6604
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.
6. vSignup Remote SQL Injection Vulnerability
BugTraq ID: 6606
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 vSignup. 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
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 vSignup 2.1.
7. Mambo Site Server Multiple Cross Site Scripting Vulnerabilities
BugTraq ID: 6571
Mambo Site Server is a freely available, open source web content management tool. It is written in PHP, and available for Unix, Linux, and Microsoft Windows operating systems. Mambo Site Server does not adequately filter 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. All code will be executed within the context of the website running Mambo Site Server. The following files were reported to be prone to cross site scripting attacks: administrator/popups/sectionswindow.php administrator/gallery/gallery.php administrator/gallery/navigation.php administrator/gallery/uploadimage.php administrator/gallery/view.php administrator/upload.php themes/mambosimple.php upload.php emailfriend/emailarticle.php emailfriend/emailfaq.php emailfriend/emailnews.php 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 Mambo Site Server 4.0.12 BETA and earlier.
8. Mambo Site Server Arbitrary File Upload Vulnerability
BugTraq ID: 6572
Mambo Site Server is a freely available, open source web content management tool. It is written in PHP, and available for Unix, Linux, and Microsoft Windows operating systems. A problem with Mambo Site Server 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 following scripts have been reported to be vulnerable to this issue:
administrator/gallery/uploadimage.php
Specifically, the scripts only check to see whether certain image extensions, such as '.jpg' and '.gif', exist in the filename. As such any file that includes the allowed extensions may be uploaded. Any uploaded files will be stored in the 'images/stories' directory on the system. 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 Mambo Site Server 4.0.12 BETA and earlier.
9. Macromedia ColdFusion MX CFInclude And CFModule Tag Sandbox Escaping Vulnerability
BugTraq ID: 6566
ColdFusion MX Enterprise Edition is the application server developing and hosting infrastructure distributed by Macromedia. It is available as a standalone product for Unix, Linux, and Microsoft Operating Systems. A problem with ColdFusion MX Enterprise Edition may allow users to access restricted files. A vulnerability in the use of the cfinclude and cfmodule Tags exists in ColdFusion MX. In environments that are sandboxed, it may be possible for a script to access files outside of the sandboxed directory. This could lead to unauthorized access to files on the host. The problem is in the handling of relative paths. Due to insufficient checking of input in custom tags, it is possible to upload a file using custom tags and containing relative paths that will access files outside of a sandboxed directory. This could allow an attacker to access unauthorized and potentially sensitive information. It should be noted that this vulnerability will only reveal the contents of files to which the ColdFusion server has read access to.
Trend Micro ScanMail is a product designed to provide antivirus support for email servers. A vulnerability has been reported for ScanMail for Microsoft Exchange. The vulnerability allows a remote attacker to bypass existing authentication mechanisms and obtain access to ScanMail's management system.
An attacker can exploit this vulnerability by making a request for the
ScanMail Exchange 6.1 has been reported to be unaffected by this vulnerability.
FormMail is a web-based e-mail gateway, which allows form-based input to be emailed to a specified user. It is written in Perl and will run on most Linux and Unix variants, in addition to Microsoft Windows operating systems. FormMail is allegedly prone to cross-site scripting attacks. The FormMail script does not sufficiently sanitize HTML tags and script code from query strings, which in turn are output into pages generated by the software. As a result, a remote attacker may construct a malicious link to the script which contains arbitrary script code. If this link is visited by a web user, the attacker-supplied script code may be interpreted by their browser in the context of the site hosting the software. This may allow an attacker to steal cookie-based authentication credentials or manipulate web content. Other attacks are also possible. This issue was reported in FormMail 1.92. Other versions may also be affected.
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.
The Half-Life client is a component of the Half-Life game distributed by Valve Software. It is available for Microsoft Windows operating systems. A problem in the Half-Life client could allow remote users to execute arbitrary code on a vulnerable host. It has been reported that the Half-Life client contains a format string vulnerability. When receiving messages from an administrator through the rcon remote administration console, the client does not properly handle input. This could result in denial of service, or code execution. The problem is in the handling of messages sent through the csay or psay commands on a standard server, or the admin_ssay and admin_psay commands when adminmod is used. The Half-Life client does not properly handle these commands, making it possible to launch an exploitable format string attack on the clients. This may permit an attacker to corrupt arbitrary locations in memory with attacker-supplied values. Any code executed on the vulnerable clients would be with the privileges of the user of the Half-Life client.
BEA Systems WebLogic Server is an enterprise level web and wireless application server for Microsoft Windows and most Unix and Linux distributions. A vulnerability in BEA Systems WebLogic Server may, under some circumstances, result in the disclosure of system passwords if exceptions are output. BEA Systems has reported that WebLogic Server will throw an exception when an application attempts to route a JMS message across a bridge and an error occurs. This exception will include the supplied system password, in plaintext. Applications that output exceptions may inadvertently disclose password values. This may ultimately result in a remote party gaining access to affected systems.
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.
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.
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.
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.
WebIntelligence is an analysis tool for business intelligence. It is distributed by Business Objects, and available for the Unix and Microsoft Windows platforms. A problem with the WebIntelligence application could make it possible for remote users to hijack sessions. It has been reported that WebIntelligence uses an insecure model for ensuring session security. The application uses web-type security features that may be prone to hijacking. This could allow a remote user to gain unauthorized access to another user's session. The problem is that the application uses cookies with guessable values to secure user sessions. It has also been suggested that a remote attacker may use other means to steal cookie-based authentication credentials from legitimate users. By gaining access to the application's session cookie, another user could gain complete access to the user's session, and perform all actions with the privileges of the victim. This vulnerability however does not permit the changing of user passwords. III. MICROSOFT FOCUS LIST SUMMARY
