Username enumeration attack in goauthentik

goauthentik is an open-source Identity Provider. In affected versions using a recovery flow with an identification stage an attacker is able to determine if a username exists. Only setups configured with a recovery flow are impacted by this. Anyone with a user account on a system with the recovery flow described above is susceptible to having their username/email revealed as existing. An attacker can easily enumerate and check users' existence using the recovery flow, as a clear message is shown when a user doesn't exist. Depending on configuration this can either be done by username, email, or both. This issue has been addressed in versions 2023.5.6 and 2023.6.2. Users are advised to upgrade. There are no known workarounds for this issue.

The commit 3730880 (April 2023) and v.0.9-beta1 of gugoan Economizzer has a user enumeration vulnerability in the login and forgot password functionalities. The app reacts differently when a user or email address is valid, and when it's not. This may allow an attacker to determine whether a user or email address is valid, or brute force valid usernames and email addresses.

User enumeration is found in in PHPJabbers Appointment Scheduler 3.0. This issue occurs during password recovery, where a difference in messages could allow an attacker to determine if the user is valid or not, enabling a brute force attack with valid users.

TOTOLINK CP300+ V5.2cu.7594 contains a Denial of Service vulnerability in function RebootSystem of the file lib/cste_modules/system which can reboot the system.

NVIDIA DGX H100 BMC and DGX A100 BMC contains a vulnerability in the host KVM daemon, where an unauthenticated attacker may cause a leak of another user’s session token by observing timing discrepancies between server responses. A successful exploit of this vulnerability may lead to information disclosure, escalation of privileges, and data tampering.

An observable response discrepancy in the Gallagher Command Centre RESTAPI allows an insufficiently-privileged user to infer the presence of items that would not otherwise be viewable. This issue affects: Gallagher Command Centre 8.70 prior to vEL8.70.1787 (MR2), 8.60 prior to vEL8.60.2039 (MR4), all version of 8.50 and prior.
