Description
OpenLiteSpeed before 1.9.3 contains a local privilege escalation vulnerability in admin/misc/lsup.sh that runs unverified update packages from a nobody-writable directory as root. Attackers controlling the nobody web process can replace the package in /usr/local/lsws/autoupdate/ before extraction, so its install.sh runs as root on the next update.
