Description:
Some vulnerabilities have been reported in phpMyChat, which can be exploited by malicious people to bypass authentication, conduct cross-site scripting and SQL injection attacks, and disclose some sensitive information.
1) It is reportedly possible to bypass the user authentication by sending a specially crafted HTTP POST request to "edituser.php3" where "do_not_login" is set to "false".
2) Input passed to the "sheet" and "What" parameters in "admin.php3" isn't validated, which can be exploited to read the content of arbitrary files via directory traversal attacks.
Successful exploitation requires administrative privileges.
3) Input passed to the "T" parameter in "messagesL.php3", the "C" parameter in "input.php3", the "FontName" and "medium" parameters in "start_page.css.php3" and "style.css.php3", and the "From" parameter in "users_popupL.php3" is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML or script code in a user's browser session in context of an affected site.
4) Input passed to various parameters in "usersL.php3" is not sanitised, which can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
5) A security issue exists where the installation script "setup.php3" is not correctly removed after installation, which can be exploited to disclose the database password and other sensitive information.
6) Input passed to the "LIMIT" parameter in chat/deluser.php3 and "Link" in chat/edituser.php3 is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
7) Input passed to the "LastCheck" and "B" parameters in chat/users_popupL.php3 is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation of these vulnerabilities requires that the target user is running a browser that has not URL-encoded the request (e.g. Internet Explorer 6).
The vulnerabilities have been reported in version 0.14.5. Prior versions may also be affected.
