CVE-2026-76413

Name of the Vulnerable Software and Affected Versions Cisco Secure FMC Software (affected versions not specified)

Description An issue exists in the Cisco Adaptive Security Device Manager (ASDM) single sign-on (SSO) handler for Cisco Secure FMC Software. This flaw results from improper management of the Cisco ASDM SSO token, which allows an unauthenticated remote attacker to perform session token forgery. A successful exploit enables the attacker to log in as the Cisco ASDM administrator user and potentially keep legitimate administrators locked out of the ASDM indefinitely.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
