The existence of the eb514ea3c45d74a1218e207fb4b345b1 value does not provide access unless an autologin=1 request is sent within an administrative session. This issue is relevant mainly when a CSRF vulnerability exists. http://forum.efrontlearning.net/viewtopic.php?f=15&t=1940 says: Admin->Maintenance->Autologin. This new tab allows to select the users that may autologin to the system via a simple link. Useful for guest users but there are many others uses as well. We do not think that intentionally setting up Autologin for an administrator is a common or plausible use case. If Autologin had been enabled for any other user account, the attacker would apparently need to know both the username and the account's creation date. Better salting would be an opportunity for security improvement. Accounts that would realistically be configured for Autologin are probably not high-value accounts, and the salt choice could be a security-versus-complexity tradeoff. - -- CVE assignment team, MITRE CVE Numbering Authority M/S M300 202 Burlington Road, Bedford, MA 01730 USA [ PGP key available through http://cve.mitre.org/cve/request_id.html ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (SunOS) iQEcBAEBAgAGBQJU2AdKAAoJEKllVAevmvmsTisH/1804w9XOS7LDUSUyqCesVEW El947wjDDb4gSQqfDX76cN0BOUahGjrJgj+9+qd+7H743UqJrV7784eBvGMa6O43 81WkQGEBqokKAr1FB0YWry2EkFsmUVpudca0Zd8nOL6WhRIJN/mG9w20AUn0TEGU nwYzehGe46gg14jkUNt1vyI4YyFtIhQATByjBUFfaSijLFf5z50UMlVS568sqOuP dsmYEOrni6hcDiKYVkFR1EQYavBvBnE0MZbCQ7j4YVuqU83QVQX4H2EyFIUpHRwM AFGkC8jGeQdNKti5YTKyUTl9EJOqi+ncCvPpLMIWYxMCGPg+Duti7Knq8xwJ6Tc= =g6vC -----END PGP SIGNATURE-----
