NO FIX YET · SEE WHAT TO DO
XWEB EVO versions 4.3.0 through 5.8.8 accept an unauthenticated POST to config.lua with action=set that writes the raw request body into /etc/xwebconfig.json. An remote attacker can tamper with model and plugin settings or put the system into an unconfigured state, causing denial of service.

Any XWEB EVO (Copeland/Dixell refrigeration and HVAC supervisor) running 4.3.0 to 5.8.8 whose web interface can be reached by an attacker, because config.lua accepts action=set and action=get without a session check. Look at supermarket, cold-chain and food-storage sites. Units reachable only from a trusted local network or behind a VPN are far less exposed; no vendor patch exists, so the fix is isolation and migration to XWEB PRO.

4.3.0 to 5.8.8 is affected)XWEB EVO 4.3.0 through 5.8.8 contains an unauthenticated arbitrary file write vulnerability that allows remote attackers to modify the system configuration file /etc/xwebconfig.json by sending a crafted POST request to config.lua with action=set, which performs no session validation and writes the raw, unvalidated request body. Attackers can tamper with configuration values such as model and plugin fields or trigger a SYSTEM_NOT_CONFIGURED state via the unauthenticated action=get and action=set operations, resulting in configuration tampering and denial of service. This product line reached it's end of service date in March 2026.
