Cisco Small Business Wireless Access Points Flaw Let Attackers Inject Commands

Cisco has alerted its customers to critical vulnerabilities in the web-based management interface of its Small Business 100, 300, and 500 Series Wireless Access Points (APs).

These flaws could allow an authenticated, remote attacker to perform command injection and buffer overflow attacks.

The vulnerabilities, identified as CVE-2024-20335 and CVE-2024-20336, are particularly concerning because they could enable an attacker with administrative credentials to execute arbitrary code as the root user on the underlying operating system of the affected devices.

This could lead to a complete compromise of the wireless access points, allowing attackers to intercept, manipulate, or disrupt network traffic.

CVE-2024-20335: Cisco Small Business 100, 300, and 500 Series Wireless APs Command Injection Vulnerability

An authenticated remote attacker may be able to carry out command injection attacks against a device that is affected by a vulnerability that exists in the web-based management interface of Cisco Small Business 100, 300, and 500 Series Wireless Access Points.
