How the Exploit Works
This exploit works by taking advantage of the deserialization process within ThemeGoods Altair. Typically, deserialization is used to convert byte streams into objects. However, if untrusted data is deserialized, it can result in a vulnerability that allows for the injection of malicious objects or code.
In the case of CVE-2025-32928, an attacker could send serialized data that includes a malicious object to the Altair system. When this data is deserialized by the system, the malicious object is processed, potentially leading to system compromise or data leakage.
Conceptual Example Code
Here’s a conceptual code example of how this vulnerability might be exploited:
POST /altair/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "serialized_object": "{malicious_object}" }In this example, the attacker sends a POST request to a vulnerable endpoint on the target system, with the serialized malicious object included in the body of the request.
Mitigation and Prevention
The most effective way to mitigate this vulnerability is by applying the patch provided by the vendor. In situations where applying the patch immediately is not feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy by identifying and blocking attempts to exploit this vulnerability.
However, it is important to note that these are temporary solutions and applying the vendor’s patch should be prioritized to fully secure your system. It’s crucial to regularly update and patch your software to prevent threats like CVE-2025-32928 from compromising your systems and data.
