Technical details
The vulnerability is an authentication bypass in lamp-cloud versions through 5.10.0, where the path pattern /*/anno/** is whitelisted for anonymous access. This allows unauthenticated attackers to send POST requests to endpoints like /defGenProject/anno/getProperties and retrieve the full JVM system property map without authentication. The root cause is overly permissive path whitelisting in the security configuration. The attack is network-reachable and requires no authentication or user interaction. Attackers can extract sensitive information including classpath, OS details, and potential startup secrets that aid in reconnaissance for further exploitation. Patches or version updates are recommended.
