Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, `ast_loggrabber` executes a `Python script` from the world-writable `/tmp` directory. An attacker already authorized to open a shell session on the Asterisk server may place a malicious script there and gain elevated privileges or execute code when an administrator runs `ast_loggrabber` as a user with elevated privileges. 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.","severity":"medium","score":6.9,"published":"2026-10-27T21:48:40.078Z","modified":"2026-10-27T21:48:40.078Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/asterisk/asterisk/security/advisories/GHSA-xgj6-2gc5-5x9c","https://github.com/asterisk/asterisk/commit/022407ec47adebe27b7ec8bcf5626e5a02fe1551","https://github.com/asterisk/asterisk/commit/a51c4e3d6bccce4bc4226c43e78952573a62f165","https://github.com/asterisk/asterisk/commit/ba8e5bdecd5280fc0ab230df59e41ea21b3a052f","https://github.com/asterisk/asterisk/commit/bd63fe121d0e86867863bd98b5771e592273b035","https://github.com/asterisk/asterisk/commit/c0fc2ae54cb6289a48a80333432f5fdf5a40c7de","https://github.com/asterisk/asterisk/commit/f18ac4c964781f671e400342790bf40679698067","https://github.com/asterisk/asterisk/releases/tag/20.20.1","https://github.com/asterisk/asterisk/releases/tag/21.12.3","https://github.com/asterisk/asterisk/releases/tag/22.10.1","https://github.com/asterisk/asterisk/releases/tag/23.4.1","https://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11","https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","https://github.com/asterisk/asterisk/tree/24.0.0-pre1"],"sources":[{"name":"CVE","id":"CVE-2026-57203","modified":"2026-10-27T21:48:40.078Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-57203"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","score":6.9}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T20:05:31.497Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
