How the CVE Works
CVE-2025-49080 is a memory management flaw in Absolute Secure Access Server (versions 9.0 to 13.54). Attackers exploiting this vulnerability send a specially crafted sequence of network packets to the server, triggering improper memory handling. This leads to a heap corruption or buffer overflow, crashing the service and causing a Denial of Service (DoS). The attack requires no authentication, user interaction, or elevated privileges, making it highly exploitable. Due to the low complexity and high availability impact, this vulnerability is classified as critical.
