Risk Analysis

This critical stack-based buffer overflow vulnerability in Tenda AC7 firmware version 15.03.06.44 allows an attacker to manipulate the 'newVersion' argument in '/goform/setNotUpgrade' to potentially execute arbitrary code or cause a denial of service. With a CVSS score of 9.8, this flaw poses a severe risk to the device's stability and security. The absence of an EPSS score means the likelihood of exploitation is not yet quantified, but the critical CVSS score indicates urgency.

No public exploit is currently known for this vulnerability. The flaw is remotely exploitable with low attack complexity, meaning an attacker can exploit it over a network without specialized conditions.

Recommended Action

Users of Tenda AC7 firmware version 15.03.06.44 should apply any available firmware updates from the vendor. Implement network segmentation and restrict access to administrative interfaces to trusted networks.

Technical Analysis

CVE-2025-11586 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
