Summary

The wildfly-core library, used by WildFly and JBoss EAP to manage server deployments, is affected. A deployment name is not sanitized, and a missing containment check in ContentRepositoryImpl.copyExplodedContent lets path traversal sequences reach files outside the deployment directory (CWE-22). An attacker with the Deployer RBAC role can delete arbitrary directories or write files with arbitrary content, which escalates to the management SuperUser role.

Description from the CNA

A flaw was found in the ContentRepositoryImpl.copyExplodedContent function of the wildfly-core library, which is used by WildFly and JBoss EAP to manage server deployments. The issue occurs when the library processes an unsanitized deployment name. Due to a missing containment check, an attacker with the Deployer RBAC role can use path traversal sequences to access files outside the restricted deployment directory. This can allow the attacker to delete arbitrary directories or create files with arbitrary content, leading to a full privilege escalation to the management SuperUser role.
