Lifecycle Timeline
2DescriptionCVE.org
CVE-2026-33444 is a memory management vulnerability in Secure Access servers prior to 14.55. Attackers with intimate knowledge of and total control over the tunnel protocol can create a non-persistent DoS against the server.
AnalysisAI
Non-persistent denial-of-service against Absolute Secure Access servers prior to version 14.55 is achievable by an attacker who has intimate knowledge of and total control over the tunnel protocol. The attack exploits a memory management flaw in the server component, causing service disruption that does not persist after the attack ends, meaning the server recovers without administrator intervention. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker possess 'intimate knowledge of' the Absolute Secure Access tunnel protocol - implying non-trivial reverse engineering or insider access to protocol specifications - AND exercise 'total control over' the tunnel protocol traffic, meaning either a man-in-the-middle position on the network path or ability to operate a fully controlled client endpoint that can send arbitrary protocol messages. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N) scores 6.9 and indicates a network-accessible, low-complexity, unauthenticated attack with only low availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A sophisticated attacker who has established a man-in-the-middle position on the network path between a legitimate client and the Secure Access server - or who controls a malicious client with deep knowledge of the tunnel protocol wire format - crafts a sequence of specially malformed tunnel protocol messages that trigger the memory management flaw in the server. The server's availability is disrupted, dropping active sessions and denying access to remote users, before the server recovers without persistent damage. … |
| Remediation | Upgrade Absolute Secure Access server to version 14.55 or later, which is the patched release indicated by the 'prior to 14.55' boundary in the vulnerability description. … Detailed patch versions, workarounds, and compensating controls in full report. |
