Detailsinfo

A vulnerability was found in pmwiki 2.1 Beta 20 (Content Management System). It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the file pmwiki.php. The manipulation of the argument GPC with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. As an impact it is known to affect integrity. The summary by CVE is:

pmwiki.php in PmWiki 2.1 beta 20, with register_globals enabled, allows remote attackers to bypass protection mechanisms that deregister global variables by setting both a GPC variable and a GLOBALS[] variable with the same name, which causes PmWiki to unset the GLOBALS[] variable but not the GPC variable, which creates resultant vulnerabilities such as remote file inclusion and cross-site scripting (XSS).

The bug was discovered 01/28/2006. The weakness was shared 01/31/2006 by Francesco "aScii" Ongaro (Website). It is possible to read the advisory at xforce.iss.net.
