CWE-321

Advantech WISE-DeviceOn Server versions prior to 5.4 contain a hard-coded cryptographic key vulnerability. The product uses a static HS512 HMAC secret for signing EIRMMToken JWTs across all installations. The server accepts forged JWTs that need only contain a valid email claim, allowing a remote unauthenticated attacker to generate arbitrary tokens and impersonate any DeviceOn account, including the root super admin. Successful exploitation permits full administrative control of the DeviceOn instance and can be leveraged to execute code on managed agents through DeviceOn’s remote management features.

Multiple Devices are Sharing the Same Secrets for SDKSocket (TCP/5000).This issue affects BLU-IC2: through 1.19.5; BLU-IC4: through 1.19.5.

Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application (VA/SaaS deployments) contain an undocumented 'printerlogic' user with a hardcoded SSH public key in '~/.ssh/authorized_keys' and a sudoers rule granting the printerlogic_ssh group 'NOPASSWD: ALL'. Possession of the matching private key gives an attacker root access to the appliance.

A vulnerability has been identified in SIMATIC RTLS Locating Manager (6GT2780-0DA00) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-0DA10) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-0DA20) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-0DA30) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-1EA10) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-1EA20) (All versions < V3.0.1.1), SIMATIC RTLS Locating Manager (6GT2780-1EA30) (All versions < V3.0.1.1). The affected systems use symmetric cryptography with a hard-coded key to protect the communication between client and server. This could allow an unauthenticated remote attacker to compromise confidentiality and integrity of the communication and, subsequently, availability of the system. A successful exploit requires the attacker to gain knowledge of the hard-coded key and to be able to intercept the communication between client and server on the network.

A hard-coded cryptographic key vulnerability was identified in Red Lion Controls Sixnet-Managed Industrial Switches running firmware Version 5.0.196 and Stride-Managed Ethernet Switches running firmware Version 5.0.190. Vulnerable versions of Stride-Managed Ethernet switches and Sixnet-Managed Industrial switches use hard-coded HTTP SSL/SSH keys for secure communication. Because these keys cannot be regenerated by users, all products use the same key. The attacker could disrupt communication or compromise the system. CVSS v3 base score: 10, CVSS vector string: (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). Red Lion Controls recommends updating to SLX firmware Version 5.3.174.

GE Multilink ML800, ML1200, ML1600, and ML2400 switches with firmware 4.2.1 and earlier and Multilink ML810, ML3000, and ML3100 switches with firmware 5.2.0 and earlier use the same RSA private key across different customers' installations, which makes it easier for remote attackers to obtain the cleartext content of network traffic by reading this key from a firmware image and then sniffing the network.

Certain Anpviz products contain a hardcoded cryptographic key stored in the firmware of the device. This affects IPC-D250, IPC-D260, IPC-B850, IPC-D850, IPC-D350, IPC-D3150, IPC-D4250, IPC-D380, IPC-D880, IPC-D280, IPC-D3180, MC800N, YM500L, YM800N_N2, YMF50B, YM800SV2, YM500L8, and YM200E10 firmware v3.2.2.2 and lower and possibly more vendors/models of IP camera.

Use of a hard-coded AES-256-CBC key in the configuration backup/restore implementation of Small Cell Sercomm SCE4255W (FreedomFi Englewood) firmware before DG3934v3@2308041842 allows remote authenticated users to decrypt, modify, and re-encrypt device configurations, enabling credential manipulation and privilege escalation via the GUI import/export functions.

In RUCKUS Network Director (RND) < 4.5.0.56, the OVA appliance contains hardcoded SSH keys for the postgres user. These keys are identical across all deployments, allowing an attacker with network access to authenticate via SSH without a password. Once authenticated, the attacker can access the PostgreSQL database with superuser privileges, create administrative users for the web interface, and potentially escalate privileges further.

User credentials are stored using AES‑ECB encryption with a hardcoded key. An unauthenticated remote attacker obtaining the configuration file can decrypt and recover plaintext usernames and passwords, especially when combined with the authentication bypass.

Bambuddy is a self-hosted print archive and management system for Bambu Lab 3D printers. Prior to version 0.1.7, a hardcoded secret key used for signing JWTs is checked into source code and ManyAPI routes do not check authentication. This issue has been patched in version 0.1.7.

Hard-coded Cryptographic Key vulnerability in Salesforce Marketing Cloud Engagement (CloudPages, Forward to a Friend, Profile Center, Subscription Center, Unsub Center, View As Webpage modules) allows Web Services Protocol Manipulation. This issue affects Marketing Cloud Engagement: before January 21st, 2026.

Delta Electronics DIAView has multiple vulnerabilities.

In Apache StreamPark versions 2.0.0 through 2.1.7, a security vulnerability involving a hard-coded encryption key exists. This vulnerability occurs because the system uses a fixed, immutable key for encryption instead of dynamically generating or securely configuring the key. Attackers may obtain this key through reverse engineering or code analysis, potentially decrypting sensitive data or forging encrypted information, leading to information disclosure or unauthorized system access. This issue affects Apache StreamPark: from 2.0.0 before 2.1.7. Users are recommended to upgrade to version 2.1.7, which fixes the issue.

The Flock Safety DetectionProcessing com.flocksafety.android.objects application 6.35.33 for Android (installed on Falcon and Sparrow License Plate Readers and Bravo Edge AI Compute Devices) bundles a Java Keystore (flock_rye.bks) along with its hardcoded password (flockhibiki17) in its code. The keystore contains a private key.

The Copypress Rest API plugin for WordPress is vulnerable to Remote Code Execution via copyreap_handle_image() Function in versions 1.1 to 1.2. The plugin falls back to a hard-coded JWT signing key when no secret is defined and does not restrict which file types can be fetched and saved as attachments. As a result, unauthenticated attackers can forge a valid token to gain elevated privileges and upload an arbitrary file (e.g. a PHP script) through the image handler, leading to remote code execution.

An issue was discovered in Siklu Communications Etherhaul 8010TX and 1200FX devices, Firmware 7.4.0 through 10.7.3 and possibly other previous versions. The rfpiped service listening on TCP port 555 which uses static AES encryption keys hardcoded in the binary. These keys are identical across all devices, allowing attackers to craft encrypted packets that execute arbitrary commands without authentication. This is a failed patch for CVE-2017-7318. This issue may affect other Etherhaul series devices with shared firmware.

The JWT secret key is embedded in the egOS WebGUI backend and is readable to the default user. An unauthenticated remote attacker can generate valid HS256 tokens and bypass authentication/authorization due to the use of hard-coded cryptographic key.

Reolink v4.54.0.4.20250526 was discovered to contain a hardcoded encryption key and initialization vector. An attacker can leverage this vulnerability to decrypt access tokens and web session tokens stored inside the app via reverse engineering.

Dpanel is a Docker visualization panel system which provides complete Docker management functions. The Dpanel service contains a hardcoded JWT secret in its default configuration, allowing attackers to generate valid JWT tokens and compromise the host machine. This security flaw allows attackers to analyze the source code, discover the embedded secret, and craft legitimate JWT tokens. By forging these tokens, an attacker can successfully bypass authentication mechanisms, impersonate privileged users, and gain unauthorized administrative access. Consequently, this enables full control over the host machine, potentially leading to severe consequences such as sensitive data exposure, unauthorized command execution, privilege escalation, or further lateral movement within the network environment. This issue is patched in version 1.6.1. A workaround for this vulnerability involves replacing the hardcoded secret with a securely generated value and load it from secure configuration storage.
