Overview
The cybersecurity world has been recently hit by a severe vulnerability, CVE-2025-32106, affecting the Audiocodes Mediapack MP-11x software versions up to 6.60A.369.002. This vulnerability allows an unauthenticated remote user to execute unauthorized code through a specifically designed POST request, potentially leading to system compromise and serious data leakage. Given the widespread usage of Audiocodes hardware in telecommunication environments, this vulnerability presents a significant risk to both individual users and large-scale organizations alike.

Audiocodes Mediapack MP-11x | Up to 6.60A.369.002
How the Exploit Works
The exploit takes advantage of a flaw within the POST request handling in the Audiocodes Mediapack MP-11x firmware. An unauthenticated remote attacker can craft a POST request, which, when processed by the vulnerable system, allows for the execution of unauthorized code. This code execution occurs due to insufficient input validation by the firmware, allowing the attacker to inject malicious code that the system then incorrectly processes as legitimate commands.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. It illustrates a malicious POST request sent to the target system.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "<INSERT MALICIOUS CODE HERE>" }Mitigation
The vendor, Audiocodes, has released a patch to mitigate this vulnerability. Users are strongly advised to apply this patch immediately. If unable to apply the patch at this time, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation by identifying and blocking such malicious POST requests. However, these measures can only serve as a temporary solution and may not fully protect the system. Therefore, patching the system should be considered a priority to ensure full protection against this critical vulnerability.
