{"id":"CVE-2026-57193","published":"2026-10-26T20:17:56.877","lastModified":"2026-10-26T20:17:56.877","description":"Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, the LDAP realtime driver `res_config_ldap` may permit `LDAP filter injection` through a `SIP username`, allowing an unauthenticated attacker to make arbitrary LDAP queries using carefully crafted SIP packets and disclose information. The `res_config_ldap` module must be loaded and configured to access an LDAP server, which is not the default. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-943"],"vendors":[],"products":[],"references":[{"url":"https://github.com/asterisk/asterisk/commit/04aa482212e43b292817444eb4de35499f4b1568","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/14968f2f440ea0dd983caa4f477237a5224904dd","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/23c01b6d359c5d85da725beea89e394a6c031c5d","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/7e1ae09594a101950398cc6aff2dd2e5ab314884","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/8170a6bfa75994e7617a8b9d7fe7a7140b70cbe2","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/dd0c768d9e9678e4cb1ed95689a254a61452239b","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/ef280572a034cac3994075298facb1999778ee0d","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/20.20.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/21.12.3","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/22.10.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/23.4.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","tags":[]},{"url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-r6c2-hwc2-j4mp","tags":[]},{"url":"https://github.com/asterisk/asterisk/tree/24.0.0-pre1","tags":[]}],"exploitRefs":[{"url":"https://github.com/asterisk/asterisk/commit/04aa482212e43b292817444eb4de35499f4b1568","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/14968f2f440ea0dd983caa4f477237a5224904dd","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/23c01b6d359c5d85da725beea89e394a6c031c5d","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/7e1ae09594a101950398cc6aff2dd2e5ab314884","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/8170a6bfa75994e7617a8b9d7fe7a7140b70cbe2","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/dd0c768d9e9678e4cb1ed95689a254a61452239b","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/ef280572a034cac3994075298facb1999778ee0d","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/20.20.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/21.12.3","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/22.10.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/23.4.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","tags":[]},{"url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-r6c2-hwc2-j4mp","tags":[]},{"url":"https://github.com/asterisk/asterisk/tree/24.0.0-pre1","tags":[]}],"hasPoc":true,"ai":null}
