Endian · Endian Firewall · CVE-2012-4923
**Name of the Vulnerable Software and Affected Versions**
Endian Firewall version 2.4
**Description**
The issue allows remote attackers to inject arbitrary web script or HTML, potentially leading to security breaches. This can be achieved via the `createrule` parameter to "dnat.cgi", the `addrule` parameter to "dansguardian.cgi", or the `PATH INFO` to "openvpn users.cgi".
**Recommendations**
For Endian Firewall version 2.4, consider disabling access to the "dnat.cgi", "dansguardian.cgi", and "openvpn users.cgi" scripts until a patch is available. Avoid using the `createrule` and `addrule` parameters in the affected API endpoints until the issue is resolved. Restrict access to the `PATH INFO` in "openvpn users.cgi" to minimize the risk of exploitation.
