Detailsinfo

A vulnerability was found in Zend Zend Platform up to 2.2.1 and classified as critical. Affected by this issue is an unknown part of the component Session Identifier. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Directory traversal vulnerability in Zend Platform 2.2.1 and earlier allows remote attackers to overwrite arbitrary files via a .. (dot dot) sequence in the final component of the PHP session identifier (PHPSESSID). NOTE: in some cases, this issue can be leveraged to perform direct static code injection.

The bug was discovered 08/21/2006. The weakness was published 08/24/2006 by Stefan Esser as not defined posting (Bugtraq). The advisory is shared for download at securityfocus.com. This vulnerability is handled as CVE-2006-4432 since 08/28/2006. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/14/2019).
