Full record on NVD

Description

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.
