The login module in Sun Java System Access Manager 6 2005Q1 (aka 6.3), 7 2005Q4 (aka 7.0), and 7.1 responds differently to a failed login attempt depending on whether the user account exists, which allows remote attackers to enumerate valid usernames.

Sun Java System Access Manager 7.1 allows remote authenticated sub-realm administrators to gain privileges, as demonstrated by creating the amadmin account in the sub-realm, and then logging in as amadmin in the root realm.

Sun Java System Access Manager 6.3 2005Q1, 7 2005Q4, and 7.1 allows remote authenticated users with console privileges to discover passwords, and obtain unspecified other "access to resources," by visiting the Configuration Items component in the console.

Unspecified vulnerability in Sun Java System Access Manager 7.0 allows local users logged in as "root" to bypass authentication and gain top-level administrator privileges via the amadmin CLI tool.

Sun Java System Access Manager (formerly Java System Identity Server) before 20070710, when the message debug level is configured in the com.iplanet.services.debug.level property in AMConfig.properties, logs cleartext login passwords, which allows local users to gain privileges by reading /var/opt/SUNWam/debug/amAuth.

Multiple cross-site scripting (XSS) vulnerabilities in Sun Java System Access Manager 6.1, 6.2, 6 2005Q1 (6.3), and 7 2005Q4 (7.0) before 20070129 allow remote attackers to inject arbitrary web script or HTML via the (1) goto or (2) gx-charset parameter.
