How the Exploit Works
The vulnerability lies in the ruleNamekey parameter in the web_acl_mgmt_Rules_Apply_post function. An attacker can send specially crafted input to this parameter, causing a stack overflow condition. This can lead to unintended execution of malicious instructions, resulting in either a system compromise or data leakage.
Conceptual Example Code
Below is a
conceptual
example of how the vulnerability might be exploited. This is a hypothetical HTTP POST request to the vulnerable endpoint:
POST /web_acl_mgmt_Rules_Apply_post HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "ruleNamekey": "A"*1000 }In this example, “A”*1000 denotes a string of 1000 ‘A’ characters. This large input could potentially overrun the buffer, causing a stack overflow.
Mitigation Guidance
The recommended mitigation is to apply the vendor’s patch as soon as it becomes available. In the meantime, or in scenarios where patching is not immediately feasible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These tools can monitor and block potentially malicious traffic, reducing the risk of successful exploitation.
Maintaining a strong security posture requires consistent vigilance and proactive measures. Users should ensure automatic updates are enabled where possible and regularly check for new security patches.
