How the Exploit Works
The CVE-2025-8245 vulnerability lies in an unknown functionality of the file /boafrm/formMultiAPVLAN of the component HTTP POST Request Handler. Specifically, the manipulation of the ‘submit-url’ argument leads to buffer overflow, a type of vulnerability where the volume of data exceeds the storage capacity of the buffer, leading to data overflow into adjacent storage.
Attackers can exploit this vulnerability by sending a specially crafted HTTP POST request with an oversized ‘submit-url’ argument. This causes the associated buffer to overflow, potentially leading to arbitrary code execution or system crashes.
Conceptual Example Code
The following is a conceptual example showing how this vulnerability might be exploited. Note that the actual malicious payload would be specific to the system configuration and the attacker’s objectives.
POST /boafrm/formMultiAPVLAN HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
submit-url=<oversized_string>In the example above, `
Mitigation Guidance
Users are strongly advised to apply the vendor-supplied patch as soon as possible to address this vulnerability. In cases where immediate application of the patch is not feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and blocking attempts to exploit this vulnerability.
Remember, staying vigilant and keeping your systems updated are key to maintaining a secure digital environment.
