libspdm is a sample implementation that follows the DMTF SPDM specifications. A vulnerability has been identified in SPDM session establishment in libspdm prior to version 2.3.1. If a device supports both DHE session and PSK session with mutual authentication, the attacker may be able to establish the session with `KEY_EXCHANGE` and `PSK_FINISH` to bypass the mutual authentication. This is most likely to happen when the Requester begins a session using one method (DHE, for example) and then uses the other method's finish (PSK_FINISH in this example) to establish the session. The session hashes would be expected to fail in this case, but the condition was not detected. This issue only impacts the SPDM responder, which supports `KEY_EX_CAP=1 and `PSK_CAP=10b` at same time with mutual authentication requirement. The SPDM requester is not impacted. The SPDM responder is not impacted if `KEY_EX_CAP=0` or `PSK_CAP=0` or `PSK_CAP=01b`. The SPDM responder is not impacted if mutual authentication is not required. libspdm 1.0, 2.0, 2.1, 2.2, 2.3 are all impacted. Older branches are not maintained, but users of the 2.3 branch may receive a patch in version 2.3.2. The SPDM specification (DSP0274) does not contain this vulnerability.

Improper Authentication in Nextcloud Server prior to version 12.0.3 would allow an attacker that obtained user credentials to bypass the 2 Factor Authentication.

In Arista's MOS (Metamako Operating System) software which is supported on the 7130 product line, under certain conditions, authentication is bypassed by unprivileged users who are accessing the Web UI. This issue affects: Arista Metamako Operating System MOS-0.34.0 and prior releases

Broken Authentication in Atlassian Connect Spring Boot (ACSB) in version 1.1.0 before 2.1.3 and from version 2.1.4 before 2.1.5: Atlassian Connect Spring Boot is a Java Spring Boot package for building Atlassian Connect apps. Authentication between Atlassian products and the Atlassian Connect Spring Boot app occurs with a server-to-server JWT or a context JWT. Atlassian Connect Spring Boot versions 1.1.0 before 2.1.3 and versions 2.1.4 before 2.1.5 erroneously accept context JWTs in lifecycle endpoints (such as installation) where only server-to-server JWTs should be accepted, permitting an attacker to send authenticated re-installation events to an app.

The All in One SEO WordPress plugin before 4.1.5.3 is affected by a Privilege Escalation issue, which was discovered during an internal audit by the Jetpack Scan team, and may grant bad actors access to protected REST API endpoints they shouldn’t have access to. This could ultimately enable users with low-privileged accounts, like subscribers, to perform remote code execution on affected sites.

Mattermost versions 8.1.x before 8.1.10, 9.2.x before 9.2.6, 9.3.x before 9.3.2, and 9.4.x before 9.4.3 fail to correctly verify account ownership when switching from email to SAML authentication, allowing an authenticated attacker to take over other user accounts via a crafted switch request under specific conditions.

Autolab, a course management service that enables auto-graded programming assignments, has misconfigured reset password permissions in version 3.0.0. For email-based accounts, users with insufficient privileges could reset and theoretically access privileged users' accounts by resetting their passwords. This issue is fixed in version 3.0.1. No known workarounds exist.

Improper Authentication vulnerability in Snow Software AB Snow License Manager on Windows allows a networked attacker to perform an Authentication Bypass if Active Directory Authentication is enabled.This issue affects Snow License Manager: from 9.33.2 through 9.34.0.

An issue has been discovered in GitLab CE/EE affecting all versions starting from 7.8 before 16.9.6, all versions starting from 16.10 before 16.10.4, all versions starting from 16.11 before 16.11.1. Under certain conditions, an attacker with their Bitbucket account credentials may be able to take over a GitLab account linked to another user's Bitbucket account, if Bitbucket is used as an OAuth 2.0 provider on GitLab.

Improper authentication in Microsoft Dataverse allows an authorized attacker to elevate privileges over a network.

An issue was discovered in OpenText Content Suite Platform 22.1 (16.2.19.1803). The request handler for ll.KeepAliveSession sets a valid AdminPwd cookie even when the Web Admin password was not entered. This allows access to endpoints, which require a valid AdminPwd cookie, without knowing the password.

Grav is a content management system (CMS). Prior to version 1.7.43, users who may write a page may use the `frontmatter` feature due to insufficient permission validation and inadequate file name validation. This may lead to remote code execution. Version 1.7.43 fixes this issue.

Code-projects Simple School Managment System 1.0 allows Authentication Bypass via the username and password parameters at School/teacher_login.php.

Arvados is an open source platform for managing and analyzing biomedical big data. In versions prior to 2.4.3, when using Portable Authentication Modules (PAM) for user authentication, if a user presented valid credentials but the account is disabled or otherwise not allowed to access the host (such as an expired password), it would still be accepted for access to Arvados. Other authentication methods (LDAP, OpenID Connect) supported by Arvados are not affected by this flaw. This issue is patched in version 2.4.3. Workaround for this issue is to migrate to a different authentication method supported by Arvados, such as LDAP.

Agentflow BPM enterprise management system has improper authentication. A remote attacker with general user privilege can change the name of the user account to acquire arbitrary account privilege, and access, manipulate system or disrupt service.

OpenObserve is a observability platform built specifically for logs, metrics, traces, analytics, designed to work at petabyte scale. A vulnerability has been identified in the "/api/{org_id}/users" endpoint. This vulnerability allows any authenticated regular user ('member') to add new users with elevated privileges, including the 'root' role, to an organization. This issue circumvents the intended security controls for role assignments. The vulnerability resides in the user creation process, where the payload does not validate the user roles. A regular user can manipulate the payload to assign root-level privileges. This vulnerability leads to Unauthorized Privilege Escalation and significantly compromises the application's role-based access control system. It allows unauthorized control over application resources and poses a risk to data security. All users, particularly those in administrative roles, are impacted. This issue has been addressed in release version 0.8.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

An issue was discovered in Mattermost Server before 4.7.0, 4.6.2, and 4.5.2. An attacker could authenticate to a different user's account via a crafted SAML response.

An issue was discovered in Aviatrix Gateway before 6.6.5712 and 6.7.x before 6.7.1376. Because Gateway API functions mishandle authentication, an authenticated VPN user can inject arbitrary commands.

An issue was discovered in Barrier before 2.4.0. The barriers component (aka the server-side implementation of Barrier) does not sufficiently verify the identify of connecting clients. Clients can thus exploit weaknesses in the provided protocol to cause denial-of-service or stage further attacks that could lead to information leaks or integrity corruption.

There is an improper authentication vulnerability in some verisons of Huawei CloudEngine product. A module does not verify the input file properly. Attackers can exploit this vulnerability by crafting malicious files to bypass current verification mechanism. This can compromise normal service.

As of v1.5.0, the default admin password is set to the argocd-server pod name. For insiders with access to the cluster or logs, this issue could be abused for privilege escalation, as Argo has privileged roles. A malicious insider is the most realistic threat, but pod names are not meant to be kept secret and could wind up just about anywhere.
