Severity: critical

Author: j4vaovo

Tags: cve2014,cve,packetstorm,msf,hfs,rce,kev,rejetto

Description

HTTP File Server before 2.3c is susceptible to remote command execution. The findMacroMarker function in parserLib.pas allows an attacker to execute arbitrary programs via a %00 sequence in a search action. Therefore, an attacker can obtain sensitive information, modify data, and/or gain full control over a compromised system without entering necessary credentials.
