Summary

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. 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.

Risk Assessment

An attacker with limited write permissions can execute arbitrary commands as root, leading to full device compromise.

Recommendation

Update travelmate to version 2.4.6-2 or later, which enforces the /etc/travelmate/*.login allowlist in the backend.

Original NVD description (English source)

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.
