CVE-2017-16613
CriticalSummary
An issue was discovered in middleware.py in OpenStack Swauth through 1.2.0 when used with OpenStack Swift through 2.15.1. The Swift object store and proxy server are saving (unhashed) tokens retrieved from the Swauth middleware authentication mechanism to a log file, allowing attackers to bypass authentication.
Risk Assessment
Attackers can exploit the saved tokens to hijack user sessions, leading to unauthorized access to resources. This poses a serious threat to data security within the organization.
Recommendation
It is recommended to upgrade to the latest version of OpenStack Swauth and Swift to mitigate this vulnerability. Additionally, access to log files containing tokens should be restricted.
Original NVD description (English source)
An issue was discovered in middleware.py in OpenStack Swauth through 1.2.0 when used with OpenStack Swift through 2.15.1. The Swift object store and proxy server are saving (unhashed) tokens retrieved from the Swauth middleware authentication mechanism to a log file as part of a GET URI. This allows attackers to bypass authentication by inserting a token into an X-Auth-Token header of a new request.
