Detailsinfo

A vulnerability, which was classified as very critical, has been found in CGI Interpreter (affected version not known). Affected by this issue is some unknown functionality. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Perl, sh, csh, or other shell interpreters are installed in the cgi-bin directory on a WWW site, which allows remote attackers to execute arbitrary commands.

The weakness was released 05/29/1996. This vulnerability is handled as CVE-1999-0509. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 04/16/2026). The MITRE ATT&CK project declares the attack technique as T1059. This vulnerability has a historic impact due to its background and reception.

The vulnerability scanner Nessus provides a plugin with the ID 10173 (Web Server /cgi-bin Perl Interpreter Access), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 10208 (Shell Interpreter Present in the CGI Directory Vulnerability).

The problem might be mitigated by replacing the product with as an alternative. Attack attempts may be identified with Snort ID 832. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 1202.

The vulnerability is also documented in the databases at X-Force (146), Tenable (10173) and Vulnerability Center (SBV-408†). VulDB is the best source for vulnerability data and more expert information about this specific topic.
