Title
fast-jwt: Empty HMAC secret accepted via async key resolver - JWT auth bypass
Summary
fast-jwt provides fast JSON Web Token (JWT) implementation. Prior to 6.2.4, a critical authentication-bypass vulnerability in fast-jwt's async key-resolver flow allows any unauthenticated attacker to forge arbitrary JWTs that are accepted as authentic. When the application's key resolver returns an empty string (''), for example via the common keys[decoded.header.kid] || '' JWKS-style fallback, fast-jwt converts it to a zero-length Buffer, hands it to crypto.createSecretKey, derives allowedAlgorithms = ['HS256','HS384','HS512'] from it, and then verifies the token's signature against an empty-key HMAC. The attacker simply computes HMAC-SHA256(key='', input='${header}.${payload}'), which Node accepts without complaint — and the verifier returns the attacker-chosen payload (sub, admin, scopes, etc.) as authentic. This vulnerability is fixed in 6.2.4.

Title
BridgeHead FileStore < 24A Apache Axis2 Default Credentials RCE
Summary
BridgeHead FileStore versions prior to 24A (released in early 2024) expose the Apache Axis2 administration module on network-accessible endpoints with default credentials that allows unauthenticated remote attackers to execute arbitrary OS commands. Attackers can authenticate to the admin console using default credentials, upload a malicious Java archive as a web service, and execute arbitrary commands on the host via SOAP requests to the deployed service.

Title
Use of Weak Credentials in Slican telephone exchanges
Summary
In Slican telephone exchanges secure key is generated in a predictable manner using properties of the telephone exchange which can be obtained without authentication. An unauthenticated attacker can deduce the secure key and obtain admin credentials. This issue was fixed in versions below: - IPx series: version 6.61.0040 - CCT-1668: version 6.56.0430 - MAC-6400: version 6.56.0430 - CXS-0424: version 6.30.0510 The issue STILL EXISTS in End-Of-Life telephone exchanges in versions 4.xx and below: - CCT-1668 (CCT1CPU) - MAC-6400 - CXS-0424 These products were discontinued in 2011 and 2012 and and will not receive updates. These products require a hardware update in order to receive a software update. The vendor recommends that users of these devices contact the their service department directly to determine the options for upgrading.

CVE-2026-22886 (GCVE-0-2026-22886)

Vulnerability from cvelistv5 – Published: 2026-03-03 09:18 – Updated: 2026-03-03 14:51
VLAI
Summary
OpenMQ exposes a TCP-based management service (imqbrokerd) that by default requires authentication. However, the product ships with a default administrative account (admin/ admin) and does not enforce a mandatory password change on first use. After the first successful login, the server continues to accept the default password indefinitely without warning or enforcement. In real-world deployments, this service is often left enabled without changing the default credentials. As a result, a remote attacker with access to the service port could authenticate as an administrator and gain full control of the protocol’s administrative features.

CVE-2026-8076 (GCVE-0-2026-8076)

Vulnerability from cvelistv5 – Published: 2026-05-08 11:55 – Updated: 2026-05-08 12:48
VLAI
Title
Weak credentials vulnerability in the CashDro 3 web administration panel
Summary
Weak credentials in the CashDro 3 web administration panel, version 24.01.00.26, where the platform allows the use of numeric PINs for user authentication. The system supports the use of PIN-based credentials, maintaining compatibility with POS software integrations deployed since 2012. This could allow an attacker to easily perform a brute-force attack against a user and gain access by trying different PINs without the account being locked. Successful exploitation of this vulnerability could result in unauthorized access to confidential configuration settings, compromising the security of the system.

Title
Use of Weak Credentials in D-Link DWR-X1820 router
Summary
Dlink DWR-X1820 router uses weak default password generated from its IMEI number and does not require users to change it. An attacker who knows how passwords are generated can easily crack the default password if they have the device IMEI number. This issue was fixed in version 1.00B16CP.

Mitigation
Architecture and Design Operation

When the user changes or sets a password, check the password against a database of already compromised or breached passwords. These passwords are likely to be used in password guessing attacks.

No CAPEC attack patterns related to this CWE.
