GHSA-4244-WG8V-Q7J8

Vulnerability from github – Published: 2022-02-15 00:02 – Updated: 2022-03-17 00:05
VLAI
Details

BD Viper LT system, versions 2.0 and later, contains hardcoded credentials. If exploited, threat actors may be able to access, modify or delete sensitive information, including electronic protected health information (ePHI), protected health information (PHI) and personally identifiable information (PII). BD Viper LT system versions 4.0 and later utilize Microsoft Windows 10 and have additional Operating System hardening configurations which increase the attack complexity required to exploit this vulnerability.

Vulnerability from github – Published: 2025-05-30 00:31 – Updated: 2025-05-30 00:31
VLAI
Details

The CS5000 Fire Panel is vulnerable due to a hard-coded password that runs on a VNC server and is visible as a string in the binary responsible for running VNC. This password cannot be altered, allowing anyone with knowledge of it to gain remote access to the panel. Such access could enable an attacker to operate the panel remotely, potentially putting the fire panel into a non-functional state and causing serious safety issues.

GHSA-434J-26H4-7637

Vulnerability from github – Published: 2025-11-04 00:32 – Updated: 2025-11-04 00:32
VLAI
Details

Deck Mate 2 is distributed with static, hard-coded credentials for the root shell and web user interface, while multiple management services (SSH, HTTP, Telnet, SMB, X11) are enabled by default. If an attacker can reach these interfaces - most often through local or near-local access such as connecting to the USB or Ethernet ports beneath the table - the built-in credentials permit administrative login and full control of the system. Once authenticated, an attacker can access firmware utilities, modify controller software, and establish persistent compromise. Remote attack paths via network, cellular, or telemetry links may exist in specific configurations but generally require additional capabilities or operator error. The vendor reports that USB access has been disabled in current firmware builds.

Summary
SQLE's JWT Secret Handler can be manipulated to use hard-coded cryptographic key
Details

A security vulnerability has been detected in actiontech sqle up to 4.2511.0. The impacted element is an unknown function of the file sqle/utils/jwt.go of the component JWT Secret Handler. The manipulation of the argument JWTSecretKey leads to use of hard-coded cryptographic key.

The attack is possible to be carried out remotely. The attack's complexity is rated as high. The exploitability is regarded as difficult. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report and is planning to fix this flaw in an upcoming release.

Mitigation
Architecture and Design
  • For outbound authentication: store passwords, keys, and other credentials outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible [REF-7].
  • In Windows environments, the Encrypted File System (EFS) may provide some protection.
Mitigation
Architecture and Design

For inbound authentication: Rather than hard-code a default username and password, key, or other authentication credentials for first time logins, utilize a "first login" mode that requires the user to enter a unique strong password or key.

Mitigation
Architecture and Design

If the product must contain hard-coded credentials or they cannot be removed, perform access control checks and limit which entities can access the feature that requires the hard-coded credentials. For example, a feature might only be enabled through the system console instead of through a network connection.

Mitigation
Architecture and Design
  • For inbound authentication using passwords: apply strong one-way hashes to passwords and store those hashes in a configuration file or database with appropriate access control. That way, theft of the file/database still requires the attacker to try to crack the password. When handling an incoming password during authentication, take the hash of the password and compare it to the saved hash.
  • Use randomly assigned salts for each separate hash that is generated. This increases the amount of computation that an attacker needs to conduct a brute-force attack, possibly limiting the effectiveness of the rainbow table method.
Mitigation
Architecture and Design
  • For front-end to back-end connections: Three solutions are possible, although none are complete.
  • The first suggestion involves the use of generated passwords or keys that are changed automatically and must be entered at given time intervals by a system administrator. These passwords will be held in memory and only be valid for the time intervals.
  • Next, the passwords or keys should be limited at the back end to only performing actions valid for the front end, as opposed to having full access.
  • Finally, the messages sent should be tagged and checksummed with time sensitive values so as to prevent replay-style attacks.
CAPEC-191: Read Sensitive Constants Within an Executable

An adversary engages in activities to discover any sensitive constants present within the compiled code of an executable. These constants may include literal ASCII strings within the file itself, or possibly strings hard-coded into particular routines that can be revealed by code refactoring methods including static and dynamic analysis.

CAPEC-70: Try Common or Default Usernames and Passwords

An adversary may try certain common or default usernames and passwords to gain access into the system and perform unauthorized actions. An adversary may try an intelligent brute force using empty passwords, known vendor default credentials, as well as a dictionary of common usernames and passwords. Many vendor products come preconfigured with default (and thus well-known) usernames and passwords that should be deleted prior to usage in a production environment. It is a common mistake to forget to remove these default login credentials. Another problem is that users would pick very simple (common) passwords (e.g. "secret" or "password") that make it easier for the attacker to gain access to the system compared to using a brute force attack or even a dictionary attack using a full dictionary.
