In certain Nedi products, a vulnerability in the web UI of NeDi login & Community login could allow an unauthenticated, remote attacker to affect the integrity of a device via a User Enumeration vulnerability. The vulnerability is due to insecure design, where a difference in forgot password utility could allow an attacker to determine if the user is valid or not, enabling a brute force attack with valid users. This affects NeDi 1.0.7 for OS X 1.0.7 <= and NeDi for Suse 1.0.7 <= and NeDi for FreeBSD 1.0.7 <=.Show less

TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that observing response time during user authentication (backend and frontend) can be used to distinguish between existing and non-existing user accounts. Extension authors of 3rd party TYPO3 extensions providing a custom authentication service should check if the extension is affected by the described problem. Affected extensions must implement new `MimicServiceInterface::mimicAuthUser`, which simulates corresponding times regular processing would usually take. Update to TYPO3 version 7.6.58 ELTS, 8.7.48 ELTS, 9.5.37 ELTS, 10.4.32 or 11.5.16 that fix this problem. There are no known workarounds for this issue.Show less

The PlexTrac platform prior to version 1.28.0 allows for username enumeration via HTTP response times on invalid login attempts for users configured to use the PlexTrac authentication provider. Login attempts for valid, unlocked users configured to use PlexTrac as their authentication provider take significantly longer than those for invalid users, allowing for valid users to be enumerated by an unauthenticated remote attacker. Note that the lockout policy implemented in Plextrac version 1.17.0 makes it impossible to distinguish between valid, locked user accounts and user accounts that do not exist, but does not prevent valid, unlocked users from being enumerated.Show less
