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.","cvssScore":6.7,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-367"],"vendors":[],"products":[],"references":[{"url":"https://github.com/litespeedtech/openlitespeed/blob/v1.9.2/dist/admin/misc/lsup.sh#L538","tags":[]},{"url":"https://github.com/litespeedtech/openlitespeed/commit/468523ce84388cea9ba6633c26517bc05b3e2bc1","tags":[]},{"url":"https://openlitespeed.org/release-log/version-1-9-x/","tags":[]},{"url":"https://www.vulncheck.com/advisories/openlitespeed-before-1.9.3-local-privilege-escalation-via-lsup-sh-auto-update","tags":[]}],"exploitRefs":[{"url":"https://github.com/litespeedtech/openlitespeed/blob/v1.9.2/dist/admin/misc/lsup.sh#L538","tags":[]},{"url":"https://github.com/litespeedtech/openlitespeed/commit/468523ce84388cea9ba6633c26517bc05b3e2bc1","tags":[]}],"hasPoc":true,"ai":null}
