CVE-2023-39953

Updating...

user_oidc provides the OIDC connect user backend for Nextcloud, an open-source cloud platform. Starting in version 1.0.0 and prior to version 1.3.3, missing verification of the issuer would have allowed an attacker to perform a man-in-the-middle attack returning corrupted or known token they also have access to. user_oidc 1.3.3 contains a patch. No known workarounds are available.

CVE-2022-41985

Updating...

An authentication bypass vulnerability exists in the Authentication functionality of Weston Embedded uC-FTPs v 1.98.00. A specially crafted set of network packets can lead to authentication bypass and denial of service. An attacker can send a sequence of unauthenticated packets to trigger this vulnerability.

CVE-2022-43635

Updating...

This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of TP-Link TL-WR940N 6_211111 3.20.1(US) routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the httpd service, which listens on TCP port 80 by default. The issue results from the incorrect implementation of the authentication algorithm. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-17332.

CVE-2023-25957

Updating...

A vulnerability has been identified in Mendix SAML (Mendix 7 compatible) (All Versions >= 1.16.4 < 1.17.2), Mendix SAML (Mendix 8 compatible) (All versions >= 2.2.0 < 2.2.3), Mendix SAML (Mendix 9 compatible, New Track) (All versions >= 3.1.9 < 3.2.5), Mendix SAML (Mendix 9 compatible, Upgrade Track) (All versions >= 3.1.9 < 3.2.5). The affected versions of the module insufficiently verifies the SAML assertions. This could allow unauthenticated remote attackers to bypass authentication and get access to the application.

CVE-2021-21378

Updating...

Envoy is a cloud-native high-performance edge/middle/service proxy. In Envoy version 1.17.0 an attacker can bypass authentication by presenting a JWT token with an issuer that is not in the provider list when Envoy's JWT Authentication filter is configured with the `allow_missing` requirement under `requires_any` due to a mistake in implementation. Envoy's JWT Authentication filter can be configured with the `allow_missing` requirement that will be satisfied if JWT is missing (JwtMissed error) and fail if JWT is presented or invalid. Due to a mistake in implementation, a JwtUnknownIssuer error was mistakenly converted to JwtMissed when `requires_any` was configured. So if `allow_missing` was configured under `requires_any`, an attacker can bypass authentication by presenting a JWT token with an issuer that is not in the provider list. Integrity may be impacted depending on configuration if the JWT token is used to protect against writes or modifications. This regression was introduced on 2020/11/12 in PR 13839 which fixed handling `allow_missing` under RequiresAny in a JwtRequirement (see issue 13458). The AnyVerifier aggregates the children verifiers' results into a final status where JwtMissing is the default error. However, a JwtUnknownIssuer was mistakenly treated the same as a JwtMissing error and the resulting final aggregation was the default JwtMissing. As a result, `allow_missing` would allow a JWT token with an unknown issuer status. This is fixed in version 1.17.1 by PR 15194. The fix works by preferring JwtUnknownIssuer over a JwtMissing error, fixing the accidental conversion and bypass with `allow_missing`. A user could detect whether a bypass occurred if they have Envoy logs enabled with debug verbosity. Users can enable component level debug logs for JWT. The JWT filter logs will indicate that there is a request with a JWT token and a failure that the JWT token is missing.

CVE-2021-25315

Vendor: Opensuse Software: Tumbleweed

A Incorrect Implementation of Authentication Algorithm vulnerability in of SUSE SUSE Linux Enterprise Server 15 SP 3; openSUSE Tumbleweed allows local attackers to execute arbitrary code via salt without the need to specify valid credentials. This issue affects: SUSE SUSE Linux Enterprise Server 15 SP 3 salt versions prior to 3002.2-3. openSUSE Tumbleweed salt version 3002.2-2.1 and prior versions.

CVE-2020-15632

Updating...

This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-842 3.13B05 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of HNAP GetCAPTCHAsetting requests. The issue results from the lack of proper handling of sessions. An attacker can leverage this vulnerability to execute arbitrary code in the context of the device. Was ZDI-CAN-10083.
