Technical details
An input validation error exists in the Absolute Security Secure Access client (formerly NetMotion) tunnel protocol handling. An attacker who has achieved total control over the tunnel protocol and possesses intimate knowledge of its inner workings can exploit this flaw to trigger a non-persistent denial-of-service (DoS) against the client. The vulnerability is categorized as a low-severity issue because it requires significant preconditions (control over the protocol) and only impacts availability temporarily without affecting data confidentiality or integrity. The issue is resolved in Secure Access client version 14.55.
