How the Exploit Works
The vulnerability lies within the function FCGI_CheckStringIfContainsSemicolon of the file /api/wizard/getLanguage of the component HTTP POST Request Handler. A successful exploit is achieved by manipulating the HTTP POST request to inject malicious commands. These commands are then executed by the system, allowing an attacker to potentially gain control over the system and compromise sensitive data.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. This is a simple HTTP POST request, where a malicious payload is embedded in the request:
POST /api/wizard/getLanguage HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "language": "en; rm -rf /" }In this example, the semicolon (;) is used to separate the valid language parameter “en” and the malicious command “rm -rf /”, which if executed, would delete all files in the system.
Please note that this is a hypothetical example, and actual attack payloads would likely be more sophisticated and tailored to the specific target environment.
Mitigation Guidance
To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by filtering out suspicious and potentially harmful traffic.
