A vulnerability has been discovered in MemHT Portal, which can be exploited by malicious users to conduct script insertion attacks.
Input passed via the "User-Agent" HTTP header to e.g. index.php (when "page" is set to "users") is not properly sanitised in inc/inc_getinfo.php before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in an administrator's browser session in context of an affected site when the malicious data is viewed.
The vulnerability is confirmed in version 4.0.1. Prior versions may also be affected.
Solution: Update to version 4.0.2.
