CVE-2009-2193

28
FAUCET Score

CVE-2009-2193 describes a critical buffer overflow vulnerability in the AppleTalk kernel component of Apple Mac OS X 10.5 prior to 10.5.8, affecting both client and server versions. This flaw allows remote, unauthenticated attackers to execute arbitrary code or trigger a denial of service (system crash) by sending specially crafted AppleTalk response packets. With a CVSS score of 10.0, it represents a severe risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
