CVE-2023-25957 1 Mendix 1 Saml 2023-08-08 N/A 7.5 HIGH
A vulnerability has been identified in Mendix SAML (Mendix 7 compatible) (All versions >= V1.16.4 < V1.17.3), Mendix SAML (Mendix 8 compatible) (All versions >= V2.2.0 < V2.3.0), Mendix SAML (Mendix 9 latest compatible, New Track) (All versions >= V3.1.9 < V3.3.1), Mendix SAML (Mendix 9 latest compatible, Upgrade Track) (All versions >= V3.1.8 < V3.3.0), Mendix SAML (Mendix 9.6 compatible, New Track) (All versions >= V3.1.9 < V3.2.7), Mendix SAML (Mendix 9.6 compatible, Upgrade Track) (All versions >= V3.1.8 < V3.2.6). The affected versions of the module insufficiently verify the SAML assertions. This could allow unauthenticated remote attackers to bypass authentication and get access to the application. For compatibility reasons, fix versions still contain this issue, but only when the recommended, default configuration option `'Use Encryption'` is disabled.
CVE-2023-3326 1 Freebsd 1 Freebsd 2023-08-01 N/A 9.8 CRITICAL
pam_krb5 authenticates a user by essentially running kinit with the password, getting a ticket-granting ticket (tgt) from the Kerberos KDC (Key Distribution Center) over the network, as a way to verify the password. However, if a keytab is not provisioned on the system, pam_krb5 has no way to validate the response from the KDC, and essentially trusts the tgt provided over the network as being valid. In a non-default FreeBSD installation that leverages pam_krb5 for authentication and does not have a keytab provisioned, an attacker that is able to control both the password and the KDC responses can return a valid tgt, allowing authentication to occur for any user on the system.
CVE-2022-33736 1 Siemens 1 Opcenter Quality 2023-07-21 5.0 MEDIUM 7.5 HIGH
A vulnerability has been identified in Opcenter Quality V13.1 (All versions < V13.1.20220624), Opcenter Quality V13.2 (All versions < V13.2.20220624). The affected applications do not properly validate login information during authentication. This could lead to denial of service condition for existing users or allow unauthenticated remote attackers to successfully login without credentials.
CVE-2022-41985 1 Weston-embedded 1 Uc-ftps 2023-05-18 N/A 7.5 HIGH
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 1 Tp-link 2 Tl-wr940n, Tl-wr940n Firmware 2023-04-07 N/A 6.5 MEDIUM
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-2018-4841 1 Siemens 2 Tim 1531 Irc, Tim 1531 Irc Firmware 2023-03-24 10.0 HIGH 9.8 CRITICAL
A vulnerability has been identified in TIM 1531 IRC (All versions < V1.1). A remote attacker with network access to port 80/tcp or port 443/tcp could perform administrative operations on the device without prior authentication. Successful exploitation could allow to cause a denial-of-service, or read and manipulate data as well as configuration settings of the affected device. At the stage of publishing this security advisory no public exploitation is known. Siemens provides mitigations to resolve it.
CVE-2022-4861 1 M-files 1 M-files Client 2023-01-06 N/A 4.9 MEDIUM
Incorrect implementation in authentication protocol in M-Files Client before 22.5.11356.0 allows high privileged user to get other users tokens to another resource.
CVE-2022-39366 1 Datahub Project 1 Datahub 2022-10-31 N/A 9.8 CRITICAL
DataHub is an open-source metadata platform. Prior to version 0.8.45, the `StatelessTokenService` of the DataHub metadata service (GMS) does not verify the signature of JWT tokens. This allows an attacker to connect to DataHub instances as any user if Metadata Service authentication is enabled. This vulnerability occurs because the `StatelessTokenService` of the Metadata service uses the `parse` method of `io.jsonwebtoken.JwtParser`, which does not perform a verification of the cryptographic token signature. This means that JWTs are accepted regardless of the used algorithm. This issue may lead to an authentication bypass. Version 0.8.45 contains a patch for the issue. There are no known workarounds.
CVE-2021-21378 1 Envoyproxy 1 Envoy 2022-10-24 6.4 MEDIUM 8.2 HIGH
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-2021-21902 1 Garrett 1 Ic Module Cma 2022-08-31 9.3 HIGH 8.1 HIGH
An authentication bypass vulnerability exists in the CMA run_server_6877 functionality of Garrett Metal Detectors iC Module CMA Version 5.0. A properly-timed network connection can lead to authentication bypass via session hijacking. An attacker can send a sequence of requests to trigger this vulnerability.
CVE-2021-32691 1 Apollosapp 1 Data-connector-rock 2022-07-02 7.5 HIGH 9.8 CRITICAL
Apollos Apps is an open source platform for launching church-related apps. In Apollos Apps versions prior to 2.20.0, new user registrations are able to access anyone's account by only knowing their basic profile information (name, birthday, gender, etc). This includes all app functionality within the app, as well as any authenticated links to Rock-based webpages (such as giving and events). There is a patch in version 2.20.0. As a workaround, one can patch one's server by overriding the `create` data source method on the `People` class.
CVE-2020-8863 1 Dlink 6 Dir-867, Dir-867 Firmware, Dir-878 and 3 more 2021-04-23 8.3 HIGH 8.8 HIGH
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-867, DIR-878, and DIR-882 routers with firmware 1.10B04. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP login requests. The issue results from the lack of proper implementation of the authentication algorithm. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the router. Was ZDI-CAN-9470.
CVE-2020-15632 1 Dlink 2 Dir-842, Dir-842 Firmware 2020-07-28 5.8 MEDIUM 8.8 HIGH
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.
CVE-2020-5268 1 Sustainsys 1 Saml2 2020-05-06 4.9 MEDIUM 7.3 HIGH
In Saml2 Authentication Services for ASP.NET versions before 1.0.2, and between 2.0.0 and 2.6.0, there is a vulnerability in how tokens are validated in some cases. Saml2 tokens are usually used as bearer tokens - a caller that presents a token is assumed to be the subject of the token. There is also support in the Saml2 protocol for issuing tokens that is tied to a subject through other means, e.g. holder-of-key where possession of a private key must be proved. The Sustainsys.Saml2 library incorrectly treats all incoming tokens as bearer tokens, even though they have another subject confirmation method specified. This could be used by an attacker that could get access to Saml2 tokens with another subject confirmation method than bearer. The attacker could then use such a token to create a log in session. This vulnerability is patched in versions 1.0.2 and 2.7.0.
CVE-2020-8861 1 Dlink 2 Dap-1330, Dap-1330 Firmware 2020-02-28 8.3 HIGH 8.8 HIGH
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DAP-1330 1.10B01 BETA Wi-Fi range extenders. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP login requests. The issue results from the lack of proper handling of cookies. An attacker can leverage this vulnerability to execute arbitrary code on the router. Was ZDI-CAN-9554.
CVE-2016-9463 2 Nextcloud, Owncloud 2 Nextcloud Server, Owncloud 2019-10-09 6.8 MEDIUM 8.1 HIGH
Nextcloud Server before 9.0.54 and 10.0.1 & ownCloud Server before 9.1.2, 9.0.6, and 8.2.9 suffer from SMB User Authentication Bypass. Nextcloud/ownCloud include an optional and not by default enabled SMB authentication component that allows authenticating users against an SMB server. This backend is implemented in a way that tries to connect to a SMB server and if that succeeded consider the user logged-in. The backend did not properly take into account SMB servers that have any kind of anonymous auth configured. This is the default on SMB servers nowadays and allows an unauthenticated attacker to gain access to an account without valid credentials. Note: The SMB backend is disabled by default and requires manual configuration in the Nextcloud/ownCloud config file. If you have not configured the SMB backend then you're not affected by this vulnerability.
