 # Openlitespeed Web Server 1.7.8 - Privilege Escalation (CVE-2021-26758)
 
+OpenLiteSpeed web server version 1.7.8 allows attackers to gain root terminal access and execute commands on the host system.
 The "path" parameter has command injection vulnerability that leads to escalate privilege.
 OpenLiteSpeed (1.7.8) web server runs with user(nobody):group(nogroup) privilege. However, extUser and
 extGroup parameters could be used to join a group (GID) such as shadow, sudo, etc.

 # Description
 I found a way to escalate privileges on Ubuntu 18.04 via OpenLiteSpeed web server that runs with *user(nobody):group(nogroup)* privilege . According to this vulnerability , system user that has admin panel credentials can add himself to sudo group or shadow group( to read /etc/shadow file) . So that the user can execute command with high privileges.
