Common Weakness Enumeration

CWE-303

Allowed

Incorrect Implementation of Authentication Algorithm

Abstraction: Base · Status: Draft

174 vulnerabilities reference this CWE, most recent first.

GHSA-5PW9-F9R4-MV2R

Vulnerability from github – Published: 2024-05-21 00:30 – Updated: 2025-08-27 21:31
VLAI
Details

An authentication bypass vulnerability was present in the GitHub Enterprise Server (GHES) when utilizing SAML single sign-on authentication with the optional encrypted assertions feature. This vulnerability allowed an attacker to forge a SAML response to provision and/or gain access to a user with site administrator privileges. Exploitation of this vulnerability would allow unauthorized access to the instance without requiring prior authentication. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.13.0 and was fixed in versions 3.9.15, 3.10.12, 3.11.10 and 3.12.4. This vulnerability was reported via the GitHub Bug Bounty program.

Details

An authentication bypass vulnerability has been identified in the REST and SOAP API components of Tripwire Enterprise (TE) 9.1.0 when TE is configured to use LDAP/Active Directory SAML authentication and its optional "Auto-synchronize LDAP Users, Roles, and Groups" feature is enabled. This vulnerability allows unauthenticated attackers to bypass authentication if a valid username is known. Exploitation of this vulnerability could allow remote attackers to gain privileged access to the APIs and lead to unauthorized information disclosure or modification.

Vulnerability from github – Published: 2023-12-27 18:30 – Updated: 2025-11-03 21:30

Details

A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory.

In adbd_tls_verify_cert of auth.cpp, there is a possible bypass of wireless ADB mutual authentication due to a logic error in the code. This could lead to remote (proximal/adjacent) code execution as the shell user with no additional execution privileges needed. User interaction is not needed for exploitation.

Vulnerability from github – Published: 2025-06-05 00:38 – Updated: 2025-06-05 00:38
VLAI
Summary
SignXML's signature verification with HMAC is vulnerable to an algorithm confusion attack
Details

When verifying signatures with X509 certificate validation turned off and HMAC shared secret set (signxml.XMLVerifier.verify(require_x509=False, hmac_key=...), prior versions of SignXML are vulnerable to a potential algorithm confusion attack. Unless the user explicitly limits the expected signature algorithms using the signxml.XMLVerifier.verify(expect_config=...) setting, an attacker may supply a signature unexpectedly signed with a key other than the provided HMAC key, using a different (asymmetric key) signature algorithm.

Starting with signxml 4.0.4, specifying hmac_key causes the set of accepted signature algorithms to be restricted to HMAC only, if not already restricted by the user.

Summary
Eclipse Dataspace Components's ConsumerPullTransferTokenValidationApiController doesn't check for token validit
Details

In Eclipse Dataspace Components, from version 0.5.0 and before version 0.9.0, the ConsumerPullTransferTokenValidationApiController does not check for token validity (expiry, not-before, issuance date), which can allow an attacker to bypass the check for token expiration. The issue requires to have a dataplane configured to support http proxy consumer pull AND include the module "transfer-data-plane". The affected code was marked deprecated from the version 0.6.0 in favour of Dataplane Signaling. In 0.9.0 the vulnerable code has been removed.

Summary
Keycloak: Revoked Tokens Can Remain Active When Both Realm-Level and Client-Level `notBefore` Revocation Policies are Configured
Details

A flaw was found in Keycloak. When both realm-level and client-level notBefore revocation policies are configured, Keycloak's OpenID Connect (OIDC) Introspection feature fails to properly honor the realm-level policy. This allows tokens that should have been revoked to remain active, potentially leading to unauthorized access or continued session validity. This could impact the security of systems utilizing Keycloak for identity and access management.

CAPEC-90: Reflection Attack in Authentication Protocol

An adversary can abuse an authentication protocol susceptible to reflection attack in order to defeat it. Doing so allows the adversary illegitimate access to the target system, without possessing the requisite credentials. Reflection attacks are of great concern to authentication protocols that rely on a challenge-handshake or similar mechanism. An adversary can impersonate a legitimate user and can gain illegitimate access to the system by successfully mounting a reflection attack during authentication.
