Pulpcore

An authenticated path traversal vulnerability in the pulpcore content upload API allows users to bypass file scheme validation and read arbitrary files on the server process by manipulating the file_url parameter.

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.
