Name of the Vulnerable Software and Affected Versions OpenStack Swauth versions through 1.2.0 OpenStack Swift versions through 2.15.1

Description An issue in the middleware.py component of OpenStack Swauth allows attackers to bypass authentication. This occurs because the Swift object store and proxy server save unhashed tokens from the Swauth middleware authentication mechanism to a log file as part of a GET URI. An attacker can exploit this by inserting a token into the X-Auth-Token header of a new request.

Recommendations For OpenStack Swauth versions through 1.2.0, consider disabling the middleware.py component until a patch is available. For OpenStack Swift versions through 2.15.1, restrict access to the log files that store the unhashed tokens to minimize the risk of exploitation.
