CVE-2012-5055

Name of the Vulnerable Software and Affected Versions Spring Security versions prior to 2.0.8 Spring Security versions 3.0.x prior to 3.0.8 Spring Security versions 3.1.x prior to 3.1.3

Description The issue allows remote attackers to potentially enumerate valid usernames via a series of login requests, due to the shorter response delay when the user is not found. This is because the DaoAuthenticationProvider does not check the password in such cases.

Recommendations For versions prior to 2.0.8, update to version 2.0.8 or later. For versions 3.0.x prior to 3.0.8, update to version 3.0.8 or later. For versions 3.1.x prior to 3.1.3, update to version 3.1.3 or later.
