A vulnerability, which was classified as problematic, was found in MiniWeb HTTP Server 0.8.19 (Web Server). Affected is the function mwgetlocalfilename of the file http.c. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as 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. This is going to have an impact on integrity. CVE summarizes:

Directory traversal vulnerability in the mwGetLocalFileName function in http.c in MiniWeb HTTP Server 0.8.19 allows remote attackers to read arbitrary files and list arbitrary directories via a (1) .%2e (partially encoded dot dot) or (2) %2e%2e (encoded dot dot) in the URI.

The weakness was disclosed 01/17/2008 by Hamid Ebadi (Website). The advisory is available at vupen.com. This vulnerability is traded as CVE-2008-0338 since 01/17/2008. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

A public exploit has been developed by Hamid Ebadi and been published before and not just after the advisory. The exploit is shared for download at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k.
