Wazuh | <= 4.5.2 How the Exploit Works
The exploit works by taking advantage of a stack overflow vulnerability in Wazuh. An attacker with low-level privileges on the system can manipulate certain functions in the software to trigger a stack overflow. This vulnerability can then be exploited to escalate the attacker’s privileges on the local system, potentially giving them full control over the system.
Conceptual Example Code
In a hypothetical exploit scenario, an attacker might use a specially crafted command like this:
$ ./wazuh_agent_control -i '[malicious_payload]'This command attempts to inject a malicious payload into the Wazuh’s agent control process, potentially leading to a stack overflow and enabling the attacker to gain higher privileges on the system. It’s important to note that this is a conceptual example, and the actual exploit may involve more complex steps and techniques.
