CVE-2025-27029: High-Risk Denial of Service Vulnerability due to Out-of-Range Tone Measurement Response Buffer

Views: 195

Overview

The vulnerability, identified as CVE-2025-27029, is a serious cybersecurity threat that can potentially lead to a transient Denial of Service (DoS) attack. This vulnerability arises due to the improper handling of an out-of-range tone measurement response buffer. Systems and networks that rely on these response buffers are at high risk, and the impact of this vulnerability could lead to system compromise or significant data leakage.

How the Exploit Works

This exploit takes advantage of a vulnerability in the processing of the tone measurement response buffer. If a malicious actor sends a response buffer that is out of the accepted range, it can cause a transient DoS condition. This would effectively render the system unresponsive, potentially leading to system compromise or data leakage.

Conceptual Example Code

A conceptual exploitation of this vulnerability might look something like this:

POST /tonemeasurement/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "response_buffer": "10000000000..." }

In this example, the “response_buffer” value is set to an out-of-range value, which could trigger the DoS condition.
