OpenWrt LuCI contains an overly permissive ACL definition in luci-mod-system-mounts that grants write access to /etc/crontabs/root to users intended only for mount configuration. Authenticated users with only the mount-configuration ACL group can append arbitrary cron entries via ubus file.write, which the default busybox crond daemon executes as root within one minute.

OpenWrt luci-app-bmx7 before commit 5890760a454dad2cb00389dba2cdc5e779e0ffdd contains a path traversal vulnerability in the bmx7-info CGI script that allows unauthenticated attackers to read files outside the configured runtimeDir. Attackers can supply directory traversal sequences in the query string to escape the intended directory and read sensitive files accessible to the CGI process.

OpenWrt luci-app-dockerman (LuCI master and openwrt-25.12 snapshots containing the ucode docker_rpc.uc RPC backend after the JS/ucode conversion) contains an OS command injection vulnerability. The package's read ACL grants broad ubus access to docker.* / docker.container.*, which exposes the docker.container.ttyd_start method even though it performs mutating operations. The run_ttyd handler build…

luci-app-https-dns-proxy contiene una vulnerabilidad de cross-site scripting (XSS) almacenado en el parámetro resolver_url que permite a usuarios autenticados inyectar HTML activo. Cuando administradores visualizan la página de estado del Proxy DNS HTTPS, la URL del resolvedor se renderiza como HTML sin sanitizar, ejecutando JavaScript en el contexto del navegador del administrador. Esta vulnerabilidad afecta principalmente a dispositivos OpenWrt en redes corporativas y de educación en LATAM.
