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.","cvss_v4":{"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},"cvss_v3":null,"cwes":["CWE-426"],"references":["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"],"products":[],"source":"nvd","synced_at":"2026-10-27T22:38:42.705297859+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
