Detection & IOCsextracted from sources · hover to see the quote

  • Target LDAP BIND requests containing abnormally long authcid (authentication identity) names, which trigger an assertion failure and crash the OpenLDAP daemon
  • Monitor for unexpected OpenLDAP daemon (slapd) crashes or aborts following receipt of BIND requests, as the assert causes program abort
  • ·Red Hat Enterprise Linux 4 and earlier are NOT vulnerable as they do not contain the vulnerable code path; RHEL 5 is also not vulnerable due to a backported patch — do not apply detection effort to these platforms
  • ·Only OpenLDAP versions prior to 2.3.29 are vulnerable; systems running 2.3.29 or later are not affected
