Privileged command execution via unchecked username
Published Jul 6, 2023 · Updated Mar 5, 2025
OS command injection in Milesight UR32L 32.3.0.5 allows remote authenticated users to execute privileged commands through the router console. The ys_thirdparty check_system_user function inserts an unchecked username into a userpermit.sh command string and passes it to popen. Administrative console access is required, and injected shell metacharacters execute arbitrary commands with the affected process's privileges.
