7.5
CVSS v3.1
Official Description
Buffer overflow in the (1) smap/smapd and (2) CSMAP daemons for Gauntlet Firewall 5.0 through 6.0 allows remote attackers to execute arbitrary code via a crafted mail message.
Technical Analysis
CVE-2001-1456 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.
