CVSS v3.1 |
| TeeKai Tracking Online 1.0 uses weak encryption of web usage statistics in data/userlog/log.txt, which allows remote attackers to identify IP's visiting the site by dividing each octet by the MD5 hash of '20'. |
| Information from SSL-encrypted sessions via PKCS #1. |
| Electronic Code Book (ECB) mode in VTun 2.0 through 2.5 uses a weak encryption algorithm that produces the same ciphertext from the same plaintext blocks, which could allow remote attackers to gain sensitive information. |
| Click2Learn Ingenium Learning Management System 5.1 and 6.1 uses weak encryption for passwords (reversible algorithm), which allows attackers to obtain passwords. |
| Use of Hard-coded Cryptographic Key vulnerability in Apache OpenMeetings.
The remember-me cookie encryption key is set to default value in openmeetings.properties and not being auto-rotated. In case OM admin hasn't changed the default encryption key, an attacker who has stolen a cookie from a logged-in user can get full user credentials.
This issue affects Apache OpenMeetings: from 6.1.0 before 9.0.0.
Users are recommended to upgrade to version 9.0.0, which fixes the issue. |
| ### Impact
When this library is used to deserialize messagepack data from an untrusted source, there is a risk of a denial of service attack by an attacker that sends data contrived to produce hash collisions, leading to large CPU consumption disproportionate to the size of the data being deserialized.
This is similar to [a prior advisory](https://github.com/MessagePack-CSharp/MessagePack-CSharp/security/advisories/GHSA-7q36-4xx7-xcxf), which provided an inadequate fix for the hash collision part of the vulnerability.
### Patches
The following steps are required to mitigate this risk.
1. Upgrade to a version of the library where a fix is available.
1. Review the steps in [this previous advisory](https://github.com/MessagePack-CSharp/MessagePack-CSharp/security/advisories/GHSA-7q36-4xx7-xcxf) to ensure you have your application configured for untrusted data.
### Workarounds
If upgrading MessagePack to a patched version is not an option for you, you may apply a manual workaround as follows:
1. Declare a class that derives from `MessagePackSecurity`.
2. Override the `GetHashCollisionResistantEqualityComparer<T>` method to provide a collision-resistant hash function of your own and avoid calling `base.GetHashCollisionResistantEqualityComparer<T>()`.
3. Configure a `MessagePackSerializerOptions` with an instance of your derived type by calling `WithSecurity` on an existing options object.
4. Use your custom options object for all deserialization operations. This may be by setting the `MessagePackSerializer.DefaultOptions` static property, if you call methods that rely on this default property, and/or by passing in the options object explicitly to any `Deserialize` method.

| The vulnerability, if exploited, could allow a miscreant with read
access to Edge Project files or Edge Offline Cache files to reverse
engineer Edge users' app-native or Active Directory passwords through
computational brute-forcing of weak hashes. |
| A low privileged local attacker can abuse the affected service by using a hardcoded cryptographic key. |
| Use of a Broken or Risky Cryptographic Algorithm vulnerability in Mia Technology Inc. Mia-Med Health Aplication allows Signature Spoofing by Improper Validation.This issue affects Mia-Med Health Aplication: before 1.0.14. |
| Use of Hard-coded Cryptographic Key vulnerability in ABB RMC-100, ABB RMC-100 LITE.
When the REST interface is enabled by the user, and an attacker gains access to
source code and control network, the attacker can bypass the REST interface authentication and gain access to MQTT configuration data.
This issue affects RMC-100: from 2105457-043 through 2105457-045; RMC-100 LITE: from 2106229-015 through 2106229-016. |
| Inadequate encryption strength for some Edge Orchestrator software for Intel(R) Tiber™ Edge Platform may allow an authenticated user to potentially enable escalation of privilege via adjacent access. |
| Programs/P73_SimplePythonEncryption.py illustrates a simple Python encryption example using the RSA Algorithm. In versions prior to commit 6ce60b1, an attacker may be able to decrypt the data using brute force attacks and because of this the whole application can be impacted. This issue has been patched in commit 6ce60b1. A workaround involves increasing the key size, for RSA or DSA this is at least 2048 bits, for ECC this is at least 256 bits. |
| CyberGhostVPNSetup.exe (Windows installer) is signed using the weak cryptographic hash algorithm SHA-1, which is vulnerable to collision attacks. This allows a malicious actor to craft a fake installer with a forged SHA-1 certificate that may still be accepted by Windows signature verification mechanisms, particularly on systems without strict SmartScreen or trust policy enforcement. Additionally, the installer lacks High Entropy Address Space Layout Randomization (ASLR), as confirmed by BinSkim (BA2015 rule) and repeated WinDbg analysis. The binary consistently loads into predictable memory ranges, increasing the success rate of memory corruption exploits. These two misconfigurations, when combined, significantly lower the bar for successful supply-chain style attacks or privilege escalation through fake installers. |
| The use of a hard-coded cryptographic key was discovered in firmware version 3.60 of the Click Plus PLC. The vulnerability relies on the fact that the software contains a hard-coded AES key used to protect the initial messages of a new KOPS session. |
| Smadar SPS – CWE-327: Use of a Broken or Risky Cryptographic Algorithm |
|
A hard-coded AES key vulnerability was reported in the Motorola GuideMe application, along with a lack of URI sanitation, could allow for a local attacker to read arbitrary files.

| A vulnerability was detected in PandaXGO PandaX up to fb8ff40f7ce5dfebdf66306c6d85625061faf7e5. This affects an unknown function of the file config.yml of the component JWT Secret Handler. The manipulation of the argument key results in use of hard-coded cryptographic key
. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is reported as difficult. The exploit is now public and may be used. This product utilizes a rolling release system for continuous delivery, and as such, version information for affected or updated releases is not disclosed. The project was informed of the problem early through an issue report but has not responded yet. |
| A vulnerability was found in Satellite. When running a remote execution job on a host, the host's SSH key is not being checked. When the key changes, the Satellite still connects it because it uses "-o StrictHostKeyChecking=no". This flaw can lead to a man-in-the-middle attack (MITM), denial of service, leaking of secrets the remote execution job contains, or other issues that may arise from the attacker's ability to forge an SSH key. This issue does not directly allow unauthorized remote execution on the Satellite, although it can leak secrets that may lead to it. |
| The AES key utilized in the pairing process between a lock using Sciener firmware and a wireless keypad is not unique, and can be reused to compromise other locks using the Sciener firmware. |
| A vulnerability has been identified in APOGEE PXC Series (BACnet) (All versions), APOGEE PXC Series (P2 Ethernet) (All versions), TALON TC Series (BACnet) (All versions). Affected devices contain a weak encryption mechanism based on a hard-coded key.
This could allow an attacker to guess or decrypt the password from the cyphertext. |
