TITLE

Cisco Small Business Series Wireless Access Points  Command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2021-007203

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. Cisco Small Business is a switch of the US Cisco (Cisco) company. Cisco Small Business has an input validation error vulnerability, which is caused by a validation error provided to the user. Attackers can use this vulnerability to execute command injections for attacks on affected devices. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements
