CVE-2025-20178 1 Cisco 1 Secure Network Analytics 2026-02-26 6 Medium
A vulnerability in the web-based management interface of Cisco Secure Network Analytics could allow an authenticated, remote attacker with valid administrative credentials to execute arbitrary commands as root on the underlying operating system. This vulnerability is due to insufficient integrity checks within device backup files. An attacker with valid administrative credentials could exploit this vulnerability by crafting a malicious backup file and restoring it to an affected device. A successful exploit could allow the attacker to obtain shell access on the underlying operating system with the privileges of root.

CVE-2025-20248 1 Cisco 1 Ios Xr Software 2026-02-26 6 Medium
A vulnerability in the installation process of Cisco IOS XR Software could allow an authenticated, local attacker to bypass Cisco IOS XR Software image signature verification and load unsigned software on an affected device. To exploit this vulnerability, the attacker must have root-system privileges on the affected device. This vulnerability is due to incomplete validation of files during the installation of an .iso file. An attacker could exploit this vulnerability by modifying contents of the .iso image and then installing and activating it on the device. A successful exploit could allow the attacker to load an unsigned file as part of the image activation process.
