Multiple vulnerabilities have been discovered in Seditio, which can be exploited by malicious users to conduct script insertion and SQL injection attacks and by malicious people to conduct cross-site request forgery attacks.
1) Input passed via the "newmsg" and "rtext" parameters to forums.php is not properly sanitised before being used. 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) Input passed via the "newpmtext" parameter to pm.php is not properly sanitised before being used. 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.
3) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. pause, un-pause, install, or un-install available plugins in the application when a logged-in administrative user visits a specially crafted web page.
4) Input passed via the "v" parameter to admin.php (when "m" is set to "hits" and "f" is set to "year") is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation of this vulnerability requires access rights to the admin section (e.g. "Moderator" access) and that "magic_quotes_gpc" is disabled.
The vulnerabilities are confirmed in version 161. Other versions may also be affected.
Solution: Edit the source code to ensure that input is properly sanitised. Do not browse untrusted sites or follow untrusted links while being logged-in to the application.
