Descriptions

An issue was discovered in OpenStack Swift before 2.28.1, 2.29.x before 2.29.2, and 2.30.0. By supplying crafted XML files, an authenticated user may coerce the S3 API into returning arbitrary file contents from the host server, resulting in unauthorized read access to potentially sensitive data. This impacts both s3api deployments (Rocky or later), and swift3 deployments (Queens and earlier, no longer actively developed).

Se descubrió un problema en OpenStack Swift anterior a 2.28.1, 2.29.x anterior a 2.29.2 y 2.30.0. Al proporcionar archivos XML manipulados, un usuario autenticado puede obligar a la API de S3 a devolver contenidos de archivos arbitrarios desde el servidor host, lo que resulta en un acceso de lectura no autorizado a datos potencialmente confidenciales. Esto afecta tanto a las implementaciones de s3api (Rocky o posterior) como a las implementaciones de swift3 (Queens y anteriores, que ya no se desarrollan activamente).

A flaw was found in Swift's S3 XML parser. By supplying specially crafted XML files, an authenticated user may coerce the S3 API into returning arbitrary file contents from the host server, resulting in unauthorized read access to potentially sensitive data. This issue impacts both s3api deployments (Rocky or later) and swift3 deployments (Queens and earlier, no longer actively developed). Only deployments with S3 compatibility enabled are affected.
