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.

H3C Magic NX15 | Up to V100R014
H3C Magic NX30 Pro | Up to V100R014
H3C Magic NX400 | Up to V100R014
H3C Magic R3010 | Up to V100R014
H3C Magic BE18000 | Up to V100R014

How the Exploit Works

The vulnerability lies in the function FCGI_CheckStringIfContainsSemicolon of the file /api/wizard/setLanguage of the component HTTP POST Request Handler. An attacker can exploit this vulnerability by manipulating the HTTP POST request to inject malicious commands. These commands are subsequently executed on the target system, potentially leading to system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit this vulnerability using a HTTP POST request:

POST /api/wizard/setLanguage HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
language=english; rm -rf /;  #This is a dangerous command that deletes all files in the system.

In this fictitious example, the attacker appends a semicolon (;) followed by a malicious command (`rm -rf /`) to the `language` parameter. The semicolon allows for command chaining in many command-line interpreters, and the `rm -rf /` command is a destructive operation that deletes all files in the system.

Mitigation

The best course of action is to apply the patch provided by the vendor. As a temporary fix, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could be used to block or alert on suspicious HTTP POST requests to `/api/wizard/setLanguage` that contain a semicolon (;) in the request body. However, this is only a stop-gap measure and the vulnerability should be properly patched as soon as possible.
