Detailsinfo

A vulnerability classified as problematic was found in PostNuke 0.750/0.760 Rc2/0.760 Rc3/0.760 Rc4 (Content Management System). This vulnerability affects the function pnmodfunc of the file pnmod.php. The manipulation of the argument func with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality. CVE summarizes:

Directory traversal vulnerability in the pnModFunc function in pnMod.php for PostNuke 0.750 through 0.760rc4 allows remote attackers to read arbitrary files via a .. (dot dot) in the func parameter to index.php.

The bug was discovered 05/03/2005. The weakness was presented 05/16/2005 by Maksymilian Arciemowicz as not defined posting (Bugtraq). The advisory is shared for download at marc.theaimsgroup.com. This vulnerability was named CVE-2005-1621 since 05/16/2005. The exploitation appears to be easy. The attack can be initiated remotely.
