CVSS v3.1
Official Description
Multiple format string vulnerabilities in heartbeat 0.4.9 and earlier (claimed as buffer overflows in some sources) allow remote attackers to execute arbitrary code via certain packets to UDP port 694 (incorrectly claimed as TCP in some sources).
Technical Analysis
CVE-2002-1215 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.
