Vulnerability Title
luci-app-travelmate - Arbitrary Command Execution via UCI Script Parameter
Vulnerability Description
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; the sink is still present in travelmate 2.4.6-1 and no patched version is known.

Vulnerability Title
OpenWRT luci 命令注入漏洞
Vulnerability Description
OpenWRT luci是OpenWRT社区开源的一款路由器配置界面。 OpenWRT luci存在命令注入漏洞,该漏洞源于LuCI/rpcd会话持有luci-app-travelmate写入ACL时,被授予了travelmate配置的全局UCI写入权限,且后端travelmate服务读取原始UCI 'script'和'script_args'值并执行配置的路径,导致具有委托写入权限的攻击者可将script设置为/bin/sh,将script_args设置为攻击者控制的参数,从而导致以root身份执行任意
