Official Description
Heap-based buffer overflow in the License Server (LicenseServer.exe) in Wavelink Terminal Emulation (TE) allows remote attackers to execute arbitrary code via a large HTTP header.
Technical Analysis
CVE-2015-4059 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
