CVE-2013-1895

Name of the Vulnerable Software and Affected Versions: py-bcrypt versions prior to 0.3

Description: The issue arises from improper handling of concurrent memory access in the py-bcrypt module, allowing attackers to bypass authentication. This is achieved through multiple authentication requests that trigger the password hash to be overwritten.

Recommendations: For versions prior to 0.3, update to version 0.3 or later to resolve the issue. As a temporary workaround, consider implementing synchronization mechanisms to prevent concurrent access to the password hash. Restrict access to authentication endpoints to minimize the risk of exploitation.
