VAR-202108-0819

Vulnerability from variot - Updated: 2023-12-18 10:45

A vulnerability in the image verification function of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker to execute code with internal user privileges on the underlying operating system. The vulnerability is due to insufficient validation of the content of upgrade packages. An attacker could exploit this vulnerability by uploading a malicious archive to the Upgrade page of the administrative web interface. A successful exploit could allow the attacker to execute code with user-level privileges (the _nobody account) on the underlying operating system. 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. Cisco Expressway Series is a software for accessing devices outside the firewall. The software provides simple, highly secure access for users outside the firewall, helping remote workers work more efficiently on the device of their choice. Cisco TelePresence Video Communication Server is a video communication server
