How the Exploit Works
The CVE-2025-31069 vulnerability exists due to insecure deserialization of user-supplied data in the HotStar – Multi-Purpose Business Theme. Insecure deserialization can lead to several security issues, as it enables an attacker to control the state or the flow of the execution of a program. In this case, the vulnerability allows an attacker to inject an object into the system, which could potentially lead to a full system compromise or data leakage.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. The attacker sends a malicious serialized object to a vulnerable endpoint on the target system:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "SerializedObjectWithMaliciousCode" }Upon receiving the malicious serialized object, the vulnerable system deserializes it, which results in the execution of the malicious code, potentially leading to system compromise or data leakage.
Mitigation
The best way to mitigate this vulnerability is by applying the vendor patch. If that is not immediately possible, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary measure to detect and prevent exploitation attempts. However, these are only temporary solutions, and applying the vendor patch should be prioritized to fully secure your systems.
