DESCRIPTION: Some vulnerabilities have been discovered in the DJ-Classifieds component for Joomla!, which can be exploited by malicious users to conduct script insertion attacks and compromise a vulnerable system.
1) Input passed via the "description" parameter to index.php (when "option" is set to "com_djclassifieds" and "view" is set to "additem") is not properly sanitised before being displayed to the user. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
2) A vulnerability is caused due to the application improperly validating uploaded files. This can be exploited to execute arbitrary PHP code by uploading a malicious PHP script with multiple extensions.
Successful exploitation of this vulnerability requires that Apache is not configured to handle the mime-type for files with an e.g. "pjpeg" extension.
The vulnerabilities are confirmed in version 0.9.1. Other versions may also be affected.
SOLUTION: Grant only trusted users access to the affected component.
DESCRIPTION: A vulnerability has been discovered in the NoticeBoard component for Joomla, which can be exploited by malicious people to disclose potentially sensitive information.
Input passed to the "controller" parameter in index.php (when "option" is set to "com_noticeboard") is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes.
The vulnerability is confirmed in version 1.3. Other versions may also be affected.
SOLUTION: Edit the source code to ensure that input is properly verified.
DESCRIPTION: A vulnerability has been discovered in the ABC component for Joomla, which can be exploited by malicious people to conduct SQL injection attacks.
Input passed via the "sectionid" parameter to index.php (when "option" is set to "com_abc") is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The vulnerability is confirmed in version 1.1.7. Other versions may also be affected.
SOLUTION: Edit the source code to ensure that input is properly sanitised.
DESCRIPTION: A vulnerability has been reported in the SmartSite component for Joomla, which can be exploited by malicious people to disclose potentially sensitive information.
Input passed to the "controller" parameter in index.php (when "option" is set to "com_smartsite") is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes.
The vulnerability is reported in version 1.0.0. Other versions may also be affected.
SOLUTION: Edit the source code to ensure that input is properly verified.
DESCRIPTION: A vulnerability has been discovered in the Graphics component for Joomla, which can be exploited by malicious people to disclose potentially sensitive information.
Input passed to the "controller" parameter in index.php (when "option" is set to "com_graphics") is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes.
The vulnerability is confirmed in version 1.5.0. Other versions may also be affected.
SOLUTION: Edit the source code to ensure that input is properly verified.
