CWE-1394

Use of Default Cryptographic Key

Category: BaseCVE: 18
Description

The product uses a default cryptographic key for potentially critical functionality.

Extended Description

It is common practice for products to be designed to use default keys. The rationale is to simplify the manufacturing process or the system administrator's task of installation and deployment into an enterprise. However, if admins do not change the defaults, it is easier for attackers to bypass authentication quickly across multiple organizations.

CVE-2024-29037

datahub-helm provides the Kubernetes Helm charts for deploying Datahub and its dependencies on a Kubernetes cluster. Starting in version 0.1.143 and prior to version 0.2.182, due to configuration issues in the helm chart, if there was a successful initial deployment during a limited window of time, personal access tokens were possibly created with a default secret key. Since the secret key is a static, publicly available value, someone could inspect the algorithm used to generate personal access tokens and generate their own for an instance. Deploying with Metadata Service Authentication enabled would have been difficult during window of releases. If someone circumvented the helm settings and manually set Metadata Service Authentication to be enabled using environment variables directly, this would skip over the autogeneration logic for the Kubernetes Secrets and DataHub GMS would default to the signing key specified statically in the application.yml. Most deployments probably did not attempt to circumvent the helm settings to enable Metadata Service Authentication during this time, so impact is most likely limited. Any deployments with Metadata Service Authentication enabled should ensure that their secret values are properly randomized. Version 0.2.182 contains a patch for this issue. As a workaround, one may reset the token signing key to be a random value, which will invalidate active personal access tokens.

CVE-2026-54887

Use of Default Cryptographic Key vulnerability in Erlang/OTP ssl (DTLS server) allows predictable DTLS cookie computation during the startup window, enabling source address verification bypass. On DTLS server startup, dtls_server_connection:initial_hello/3 initializes previous_cookie_secret to the empty binary (<<>>) instead of a random value. Because HMAC with an empty key is deterministic, anyone who observes the plaintext ClientHello can compute dtls_handshake:cookie(<<>>, IP, Port, Hello) and forge a valid DTLS cookie before the first rotation of the cookie secret. The DTLS cookie (RFC 6347 §4.2.1) is a denial-of-service mitigation that prevents spoofed source IPs from forcing the server to allocate state and perform expensive cryptographic operations; it is not an authentication mechanism. During the window from server startup until the first secret rotation (0 to 15 seconds), an attacker who can observe the plaintext ClientHello can bypass the source address verification, enabling DTLS handshake amplification with spoofed source addresses. This vulnerability is associated with program file lib/ssl/src/dtls_server_connection.erl and program routine dtls_server_connection:initial_hello/3. This issue affects OTP from OTP 20.0 before 29.0.3, 28.5.0.3 and 27.3.4.14 corresponding to ssl from 8.2 before 11.7.3, 11.6.0.3 and 11.2.12.10.

CVE-2026-5039

TP-Link TL-WR841N v13 uses DES-CBC encryption in the TDDPv2 debug protocol with a cryptographic key derived from default web management credentials, making the key predictable if device is left in default configuration. A network-adjacent attacker can exploit this weakness to gain unauthorized access to the protocol, read debug data, modify certain device configuration values, and trigger device reboot, resulting in loss of integrity and a denial-of-service condition.

CVE-2026-20709

Use of Default Cryptographic Key in the hardware for some Intel(R) Pentium(R) Processor Silver Series, Intel(R) Celeron(R) Processor J Series, Intel(R) Celeron(R) Processor N Series may allow an escalation of privilege. Hardware reverse engineer adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via physical access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.

CVE-2025-1688

Milestone Systems has discovered a security vulnerability in Milestone XProtect installer that resets system configuration password after the upgrading from older versions using specific installers. The system configuration password is an additional, optional protection that is enabled on the Management Server. To mitigate the issue, we highly recommend updating system configuration password via GUI with a standard procedure. Any system upgraded with 2024 R1 or 2024 R2 release installer is vulnerable to this issue. Systems upgraded from 2023 R3 or older with version 2025 R1 and newer are not affected.

CVE-2026-25815

Fortinet FortiOS through 7.6.6 allows attackers to decrypt LDAP credentials stored in device configuration files, as exploited in the wild from 2025-12-16 through 2026 (by default, the encryption key is the same across all customers' installations). NOTE: the Supplier's position is that the instance of CWE-1394 is not a vulnerability because customers "are supposed to enable" a non-default option that eliminates the weakness. However, that non-default option can disrupt functionality as shown in the "Managing FortiGates with private data encryption" document, and is therefore intentionally not a default option.
