Pulpcore

An authenticated administrator can exploit a path traversal vulnerability in the 'relative_path_validator' function within 'pulpcore'. During 'FilesystemExport' operations, specially crafted 'relative_path' values containing directory traversal sequences (e.g., "../") can bypass validation, leading to arbitrary file writes. This allows an attacker to write files to any location writable by the Pulp service user, such as '/etc/shadow', potentially leading to service compromise, privilege escalation, or further system exploitation.
