Descriptionluci-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; the sink is still present in travelmate 2.4.6-1 and no patched version is known.
