lamp-cloud through 5.10.0 whitelists the path pattern /*/anno/** for anonymous access, allowing unauthenticated attackers to read the server's full JVM system property map. Attackers can send POST requests to /defGenProject/anno/getProperties to retrieve sensitive information including JVM classpath, filesystem paths, operating system details, and startup secrets.

lamp-cloud versions through 5.10.0 contain a missing authentication vulnerability where the path pattern /*/anno/** is whitelisted for anonymous access. Unauthenticated attackers can send POST requests to /defGenProject/anno/getProperties to retrieve the server's full JVM system property map. Sensitive information exposed includes JVM classpath, filesystem paths, operating system details, and startup secrets. The vulnerability stems from an overly permissive anonymous access whitelist configured in IgnoreProperties.java. The affected endpoint is implemented in DefGenProjectController.java. No authentication or authorization is required to exploit this issue. This represents a significant information disclosure risk that could facilitate further attacks.
