CVE-2010-1840

40
FAUCET Score

CVE-2010-1840 describes a stack-based buffer overflow vulnerability within the password-validation functionality of Directory Services in Apple Mac OS X 10.5.8 and 10.6.x prior to 10.6.5. This flaw allows remote attackers to execute arbitrary code or cause a denial of service through unspecified vectors. With a CVSS score of 7.5, this vulnerability is considered highly severe due to its network-based attack vector, low attack complexity, and potential for complete compromise of confidentiality, integrity, and availability. While not listed on the KEV catalog and lacking Metasploit or Nuclei modules, a public exploit (EDB-15491) exists, though there is no evidence of active exploitation or significant community discussion.
