Description
Copeland XWEB EVO versions 4.3.0 through 5.8.8 have an unauthenticated arbitrary file write vulnerability. Remote attackers can send crafted POST requests to config.lua with action=set to modify the system configuration file /etc/xwebconfig.json without any session validation. This allows tampering with configuration values or triggering a denial of service by causing a SYSTEM_NOT_CONFIGURED state. The product line reached end of service in March 2026.
