Lifecycle Timeline
3DescriptionCVE.org
CVE-2026-33443 is a memory management error in Secure Access servers prior to 14.55. Attackers with an intimate knowledge of and total control over the tunnel protocol can create a persistent DoS against the server.
AnalysisAI
Persistent denial-of-service in Absolute Secure Access servers before version 14.55 allows an authenticated tunnel participant to permanently crash or wedge the server by abusing the tunnel protocol. The CVSS 4.0 vector (7.1, PR:L, VA:H) confirms an availability-only impact requiring some level of tunnel authentication, with no confidentiality or integrity effect despite a mislabeled 'Information Disclosure' tag. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV.
