Cisco Small Business 100, 300, and 500 Series Wireless Access Points Command Injection Vulnerabilities
Description
Multiple vulnerabilities in the web-based management interface of certain Cisco Small Business 100, 300, and 500 Series Wireless Access Points could allow an authenticated, remote attacker to perform command injection attacks against an affected device. These vulnerabilities are due to improper validation of user-supplied input. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to the web-based management interface of an affected system. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the device. To exploit these vulnerabilities, the attacker must have valid administrative credentials for the device.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Authenticated command injection in Cisco Small Business 100/300/500 series WAPs allows arbitrary root command execution.
Vulnerability
Multiple command injection vulnerabilities exist in the web-based management interface of certain Cisco Small Business 100, 300, and 500 Series Wireless Access Points. The vulnerabilities are due to improper validation of user-supplied input. Affected models include WAP125 (fixed in 1.0.4.3), WAP150 (fixed in 1.1.3.2), WAP361 (fixed in 1.1.3.2), and WAP581 (fixed in 1.0.4.4). WAP121, WAP131, WAP321, and WAP351 are end-of-life and will not receive fixes [1].
Exploitation
An attacker must have valid administrative credentials for the device. The attacker can send crafted HTTP requests to the web-based management interface to trigger the vulnerability. No user interaction is required beyond authentication [1].
Impact
Successful exploitation allows the attacker to execute arbitrary commands with root privileges on the affected device, leading to full compromise of the access point [1].
Mitigation
Cisco has released fixed firmware versions as listed above. Customers with WAP125, WAP150, WAP361, or WAP581 should upgrade to the specified fixed releases. For end-of-life models (WAP121, WAP131, WAP321, WAP351), no patches are available; migration to a supported product is recommended [1].
