CVE-2024-20488Network attack vector

Script execution via improper web input validation

Published Aug 21, 2024 · Updated Aug 21, 2024

Cross-site scripting in Cisco Unified Communications Manager allows remote attackers to execute script through a crafted management link. The web-based management interface does not properly validate user-supplied input, but Cisco has not identified the affected parameter or processing function. Exploitation requires a user of the interface to click the link and exposes browser-based information or permits actions in that interface's context.
