15
FAUCET Score

CVE-2012-1164 describes a denial-of-service vulnerability in OpenLDAP versions prior to 2.4.30, where a remote attacker can crash the slapd daemon by sending an LDAP search query with the attrsOnly parameter set to true, leading to an assertion failure due to empty attributes being returned. The vulnerability has a low CVSS score of 2.6 (AV:N/AC:H/Au:N/C:N/I:N/A:P), indicating a network-based attack with high access complexity and potential for partial availability impact. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not a widely targeted or discussed vulnerability.
