How to fix or mitigate CVE-2025-20674?

Within 24 hours: Inventory all wireless access points and identify affected models/firmware versions; isolate critical APs from production if possible and enable enhanced monitoring. Within 7 days: Implement network segmentation to restrict AP management access, disable non-essential wireless features if applicable, and establish daily vulnerability scanning for exploitation attempts. Within 30 days: Monitor vendor patch availability and establish expedited deployment procedures; conduct post-patch network security assessment and review wireless access logs for signs of compromise.

DescriptionCVE.org

In wlan AP driver, there is a possible way to inject arbitrary packet due to a missing permission check. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00413202; Issue ID: MSV-3303.

Executive ViewAI

Why It Matters

A critical vulnerability in wireless access point drivers allows remote attackers to inject arbitrary packets and escalate privileges without authentication or user interaction, potentially compromising network security across all connected devices. This poses an immediate risk to organizational data, customer information, and system availability, particularly affecting businesses relying on Wi-Fi infrastructure for operations.

Business Impact: Severe

Compensating Controls

Implement strict network segmentation isolating wireless infrastructure from critical systems; deploy enhanced monitoring and IDS/IPS rules to detect arbitrary packet injection attempts; restrict administrative access to APs via MAC filtering and IP allowlisting; disable WPS and other non-essential wireless features; enforce certificate-based authentication where supported; monitor vendor advisories closely for patch ETA and establish pre-approved change management for rapid deployment when available.

Attack Technique

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
