Details

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.

Severity
9.0 (Critical)
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:H/A:H
