{"id":"CVE-2026-58652","summary":"luci-app-travelmate - Arbitrary Command Execution via UCI Script Parameter","details":"luci-app-travelmate (and the travelmate package) contain a privilege-escalation flaw: a LuCI/rpcd session holding the luci-app-travelmate write ACL is granted config-wide UCI write access to the travelmate configuration. While the LuCI UI restricts the auto-login script picker to /etc/travelmate/*.login, this is only a frontend restriction. The backend travelmate service (running as root) reads the raw UCI 'script' and 'script_args' values and executes the configured path when the captive-portal auto-login branch (f_check() in travelmate-functions.sh) is reached. An attacker with delegated write permissions can set script to /bin/sh and script_args to attacker-controlled arguments, resulting in arbitrary command execution as root. Confirmed in luci-app-travelmate/travelmate 2.4.5-r3; travelmate 2.4.6-1 is also affected. Fixed in travelmate 2.4.6-2, which enforces the /etc/travelmate/*.login allowlist in the backend.","aliases":["GHSA-p35r-3323-6g7g"],"modified":"2026-11-09T02:31:02.347237218Z","published":"2026-07-02T12:28:34.022Z","database_specific":{"cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/58xxx/CVE-2026-58652.json","unresolved_ranges":[{"extracted_events":[{"range":[{"introduced":"2.4.5-r3"},{"last_affected":"2.4.5-r3"}],"source":"AFFECTED_FIELD","strategy":"StandaloneSingleVersion"}]},{"extracted_events":[{"range":[{"fixed":"2.4.6-2"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}],"cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/58xxx/CVE-2026-58652.json"},{"type":"ADVISORY","url":"https://github.com/openwrt/luci/security/advisories/GHSA-p35r-3323-6g7g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58652"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/luci-app-travelmate-arbitrary-command-execution-via-uci-script-parameter"},{"type":"FIX","url":"https://github.com/openwrt/packages/commit/0627b412ee3a760cc4bca9fc8a5b73de8f33ac10"},{"type":"FIX","url":"https://github.com/openwrt/packages/commit/71d92bcc9edbc8f95858ce82a8ff5d52500005a2"},{"type":"FIX","url":"https://github.com/openwrt/packages/commit/d6e457a1a70a9010195edeafdc0b8eb6e3b0f7f1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openwrt/packages","events":[{"introduced":"0"},{"fixed":"71d92bcc9edbc8f95858ce82a8ff5d52500005a2"},{"fixed":"0627b412ee3a760cc4bca9fc8a5b73de8f33ac10"},{"fixed":"d6e457a1a70a9010195edeafdc0b8eb6e3b0f7f1"}],"database_specific":{"extracted_events":[{"range":[{"fixed":"71d92bcc9edbc8f95858ce82a8ff5d52500005a2"}],"source":"REFERENCES_COMMIT"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"0627b412ee3a760cc4bca9fc8a5b73de8f33ac10"}]},{"source":"REFERENCES_COMMIT","range":[{"fixed":"d6e457a1a70a9010195edeafdc0b8eb6e3b0f7f1"}]}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-58652.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
