What to do

AI-suggested

Since the vulnerabilities require authenticated HTTP requests, restricting access to the device's management interface and limiting administrative privileges can reduce risk. Monitor the vendor's advisory for updates and apply patches promptly once released.

Description

Multiple buffer overflow vulnerabilities have been identified in the internet.cgi set_qos() functionality of the Wavlink AC3000 M33A8.V5030.210505 router firmware. These vulnerabilities arise from improper handling of the en_enable POST parameter, allowing an authenticated attacker to trigger stack-based buffer overflows via specially crafted HTTP requests. The vulnerabilities have a critical severity rating with a CVSS score of 9.1, indicating high impact on confidentiality, integrity, and availability.
