Detailsinfo

A vulnerability has been found in phpBB (Forum Software) and classified as critical. Affected by this vulnerability is an unknown function of the file get/post/cookie. 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 confidentiality, integrity, and availability. The summary by CVE is:

phpBB 2.0.17 and earlier allows remote attackers to bypass protection mechanisms that deregister global variables by setting both a GET/POST/COOKIE (GPC) variable and a GLOBALS[] variable with the same name, which causes phpBB to unset the GLOBALS[] variable but not the GPC variable.

The bug was discovered 08/14/2005. The weakness was released 10/31/2005 by Stefan Esser with Hardened-PHP Project (Website). The advisory is shared at hardened-php.net. This vulnerability is known as CVE-2005-3415 since 11/01/2005. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1059.007 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 78 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 20132 (phpBB <= 2.0.17 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses and running in the context r.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (22914), Tenable (20132), SecurityFocus (BID 15243†), OSVDB (20386†) and Secunia (SA17366†).
