"value": "A path traversal vulnerability was found in pulpcore. The relative_path_validator function only verifies that content paths do not begin with \"/\" but fails to block directory traversal sequences such as \"../\" anywhere in the path. An authenticated administrator can craft a relative_path containing embedded traversal sequences (e.g., \"looking/normal/../../../../etc/shadow\") that escapes the intended export directory during FilesystemExport operations. Because the file content is also user-controlled (uploaded artifact), this allows arbitrary file write to any location writable by the Pulp service user, potentially leading to service compromise or further system exploitation."

"value": "There is no complete mitigation for this vulnerability. The following measures can reduce risk:\n\n1. If FilesystemExport was never configured on your deployment, you are not affected by this issue.\n2. If FilesystemExporters exist in the database, audit them for path traversal sequences (\"../\"). Existing malicious entries must be cleaned up manually, as the validation functions documented to raise ValidationError do not actually do so in all code paths.\n3. Restrict admin-level access to the Pulp API to only trusted operators. Review and audit which accounts have administrator privileges.\n4. Ensure SELinux is in enforcing mode on Satellite/Pulp servers to limit the directories the Pulp service user can write to.\n5. Monitor filesystem changes outside of expected Pulp directories for signs of exploitation."
