Description:
Some vulnerabilities have been discovered in Zorum, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks, and to compromise a vulnerable system.
1) Input passed to the "argv[1]" parameter in gorum/prod.php is not properly sanitised before being used in the "system()" function. This can be exploited to execute arbitrary commands on the server.
Example:
http://[host]/zorum/gorum/prod.php?argv[1]=|[command]
Successful exploitation requires that "register_globals" is enabled and "register_argc_argv" is disabled.
2) Input passed to the "rollid" and "offset" parameters in "index.php" isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
3) Input passed to the "method" and "frommethod" parameters in "index.php" isn't 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.
The vulnerabilities have been confirmed in version 3.5. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised.
