Cisco’s ISE Flaws Fixed: Hackers’ Privilege Party Cut Short
Cisco patched two critical flaws in Identity Services Engine, preventing remote code execution and privilege escalation. Vulnerabilities CVE-2025-20124 and CVE-2025-20125 could allow attackers to execute commands and alter configurations. Cisco urges users to update software, as no workarounds exist. Fortunately, no active exploitation has been detected in the wild.

Hot Take:
Looks like Cisco’s Identity Services Engine was playing a dangerous game of “Java Jenga” and “Authorization Limbo.” Thankfully, they’ve pulled the emergency brake just in time to prevent a server-side apocalypse and save us from a cyber soap opera starring rogue Java objects and sneaky credentials.
