Detailsinfo

A vulnerability has been found in HFS HTTP File Server up to 2.x and classified as critical. This vulnerability affects an unknown functionality. The manipulation of the argument /?%0a 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, integrity, and availability. CVE summarizes:

Multiple directory traversal vulnerabilities in HTTP File Server (HFS) before 2.2c, when account names are used as log filenames, allow remote attackers to create arbitrary (1) files and (2) directories via a .. (dot dot) in an account name, when requesting the / URI; and (3) append arbitrary data to a file via a .. (dot dot) in an account name, when requesting a URI composed of a "/?%0a" sequence followed by the data.

The weakness was published 01/28/2008 by STORM (Website). The advisory is shared for download at securityfocus.com. This vulnerability was named CVE-2008-0405 since 01/22/2008. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details and also a public exploit are known.
