Summary

A flaw was found in wildfly-core. A remote attacker, authenticated as a 'deployer' account, can import and deploy a malicious archive file from an untrusted source. This is achieved by leveraging WildFly libraries to craft a Java project that allows an HTTP POST request to upload and deploy the malicious archive. This could lead to further exploitation, such as arbitrary file read vulnerabilities.
