Citrix Bleed 2: The Unpatched ADC Comedy of Errors Exposing 1,200+ Appliances!
Over 1,200 Citrix NetScaler appliances are unpatched against a critical vulnerability dubbed Citrix Bleed 2. This flaw allows attackers to hijack user sessions with the finesse of a cat burglar. In other news, 2,100 devices still play host to another bug, proving that not all patches are created equal.
Hot Take:
Looks like Citrix devices are having their own “Bleed” sequel, but this time it’s less of a horror movie and more of a cybersecurity thriller. With over 1,200 unpatched appliances, it’s like leaving your front door wide open during a neighborhood crime spree. Time for Citrix admins to don their superhero capes and patch those vulnerabilities before the villains exploit them faster than you can say “out-of-bounds memory read.”
Key Points:
- CVE-2025-5777, dubbed “Citrix Bleed 2,” enables attackers to bypass authentication by hijacking user sessions.
- Over 1,200 Citrix appliances exposed online remain unpatched against this vulnerability.
- Successful exploitation can lead to stealing session tokens, credentials, and other sensitive data.
- Citrix advised terminating all active ICA and PCoIP sessions post-upgrade to block attacks.
- Security firm ReliaQuest reports medium confidence in active exploitation of this flaw, despite Citrix’s lack of evidence.
