SECUNIA ADVISORY ID: SA38486

VERIFY ADVISORY: http://secunia.com/advisories/38486/

DESCRIPTION: A vulnerability has been discovered in httpdx, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.

The vulnerability is caused due to a format string error within the “f_command()” function in httpdx_src/ftp.cpp, which can be exploited to cause a crash and potentially execute arbitrary code by sending a specially crafted FTP command containing format string specifiers to the server.

The vulnerability is confirmed in version 1.5.2. Other versions may also be affected.

SOLUTION: Use in trusted networks only. Block access to the FTP service.
