Cisco Releases Patch for CVE-2025-20188 – 10.0 CVSS

Written by

A critical vulnerability in Cisco Catalyst 9800 wireless controllers could allow attackers to gain remote root access by exploiting a hard-coded JSON Web Token (JWT) in the Out-of-Band AP Image Download feature, which is disabled by default.

Administrators should verify if this feature is enabled and disable it as a temporary mitigation. Cisco has released patches to fully remediate the issue, and Raxis strongly recommends updating to the latest software version as soon as possible.

The Raxis team is reaching out to all Raxis Attack customers who may be affected.

Human Vs AI Pentesting

While AI tools offer speed in detecting known vulnerabilities, they fall short with 20-35% false positives and only 50-65% success on complex threats like business logic flaws, as per mainstream reports from Verizon and OWASP. Human penetration testers at Raxis deliver 85-90% detection rates, precise prioritization, and ethical adaptability, ensuring your organization stays ahead of real-world attacks.
