Loading vulnerability…
CVE-2012-4031 describes multiple directory traversal vulnerabilities in the src/acloglogin.php script of Wangkongbao CNS-1000 and 1100 devices. The vulnerability is triggered by improper sanitization of the 'lang' and 'langid' cookies, which are processed by the application when accessed via port 85. By supplying directory traversal sequences (../), a remote attacker can access arbitrary files on the system.

This repository contains a single Metasploit auxiliary scanner module targeting a directory traversal vulnerability (CVE-2012-4031) in WANGKONGBAO CNS-1000 and 1100 UTM appliances. The exploit leverages a flaw in the web interface (specifically /src/acloglogin.php on TCP port 85) to read arbitrary files from the filesystem by injecting directory traversal sequences into the Cookie header of an HTTP request. The module allows the user to specify the file path and traversal depth, with defaults set to retrieve sensitive files such as /etc/shadow or /etc/passwd. The exploit is operational and can be used to exfiltrate any file readable by the web server, which runs as root. The code is written in Ruby and is structured as a standard Metasploit module.
