Cisco Nexus Dashboard configuration backup feature allows authenticated administrators to extract sensitive authentication credentials from encrypted backup files, enabling subsequent unauthorized access to internal APIs and arbitrary root-level command execution on the underlying operating system. The vulnerability requires possession of both a valid backup file and its encryption password, limiting exploitation to administrators or attackers with backup file access. CVSS 6.5 reflects the high-privilege requirement (PR:H) despite high confidentiality and integrity impact; no public exploit or active exploitation has been identified.

Cisco Catalyst SD-WAN Manager's web interface contains a reflected cross-site scripting (XSS) vulnerability that requires user interaction and authentication to exploit. An attacker can craft a malicious link to execute arbitrary JavaScript in a victim's browser session, potentially stealing sensitive information or performing unauthorized actions within the management interface. No patch is currently available.

A stored cross-site scripting (XSS) vulnerability exists in the web-based Cisco IOx application hosting environment management interface within Cisco IOS XE Software, allowing authenticated remote attackers with administrative credentials to inject malicious scripts that execute in the context of other users' browser sessions. Successful exploitation enables arbitrary script execution and access to sensitive browser-based information affecting a wide range of Cisco IOS XE versions from 16.6.1 through 17.18.1a. This vulnerability requires valid administrative credentials and user interaction but poses a significant risk in multi-administrator environments where privilege escalation or lateral movement could occur.
