CVSS v3.1 |
| A vulnerability classified as problematic was found in FNKvision FNK-GU2 up to 40.1.7. Affected by this vulnerability is an unknown functionality of the file /etc/shadow of the component MD5. The manipulation leads to risky cryptographic algorithm. It is possible to launch the attack on the physical device. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. |
| ### 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.

| Inadequate encryption strength issue exists in SS1 Ver.16.0.0.10 and earlier (Media version:16.0.0a and earlier). If this vulnerability is exploited, a function that requires authentication may be accessed by a remote unauthenticated attacker. |
| Due to Nonce reuse, attackers can perform reply attack or decrypt captured packets. |
| 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. |
| Use of hard-coded cryptographic key issue exists in AIPHONE IX SYSTEM, IXG SYSTEM, and System Support Software. A network-adjacent unauthenticated attacker may log in to SFTP service and obtain and/or manipulate unauthorized files. |
| A private key disclosure vulnerability exists in ZTE's ZXMP M721 product. A low-privileged user can bypass authorization checks to view the device's communication private key, resulting in key exposure and impacting communication security. |
| CWE-328: Use of Weak Hash |
| sftpgo is a full-featured and highly configurable event-driven file transfer solution. Server protocols: SFTP, HTTP/S, FTP/S, WebDAV. The OpenID Connect implementation allows authenticated users to brute force session cookies and thereby gain access to other users' data, since the cookies are generated predictably using the xid library and are therefore unique but not cryptographically secure. This issue was fixed in version v2.6.4, where cookies are opaque and cryptographically secure strings. All users are advised to upgrade. There are no known workarounds for this vulnerability. |
| The Use of a Hard-coded Cryptographic Key vulnerability in Juniper Networks Juniper Cloud Native Router (JCNR) and containerized routing Protocol Deamon (cRPD) products allows an attacker to perform Person-in-the-Middle (PitM) attacks which results in complete compromise of the container.
Due to hardcoded SSH host keys being present on the container, a PitM attacker can intercept SSH traffic without being detected.
This issue affects Juniper Networks JCNR:
* All versions before 23.4.
This issue affects Juniper Networks cRPD:
* All versions before 23.4R1. |

| The Bastion provides authentication, authorization, traceability and auditability for SSH accesses. Session-recording ttyrec files, may be handled by the provided osh-encrypt-rsync script that is a helper to rotate, encrypt, sign, copy, and optionally move them to a remote storage periodically, if configured to. When running, the script properly rotates and encrypts the files using the provided GPG key(s), but silently fails to sign them, even if asked to. |
| Missing cryptographic key commitment in the AWS SDK for C++ may allow a user with write access to the S3 bucket to introduce a new EDK that decrypts to different plaintext when the encrypted data key is stored in an "instruction file" instead of S3's metadata record.
To mitigate this issue, upgrade AWS SDK for C++ to version 1.11.712 or later |
| The devices are vulnerable to an authentication bypass due to flaws in the authorization mechanism. An unauthenticated remote attacker could exploit this weakness by performing brute-force attacks to guess valid credentials or by using MD5 collision techniques to forge authentication hashes, potentially compromising the device. |
| Inadequate Encryption Strength vulnerability allow an authenticated attacker to execute arbitrary OS Commands via encrypted package upload.This issue affects Envoy: 4.x and 5.x |
| Missing cryptographic key commitment in the Amazon S3 Encryption Client for Go may allow a user with write access to the S3 bucket to introduce a new EDK that decrypts to different plaintext when the encrypted data key is stored in an "instruction file" instead of S3's metadata record.
To mitigate this issue, upgrade Amazon S3 Encryption Client for Go to version 4.0 or later. |
| The Fedora Secure Boot CA certificate shipped with shim in Fedora was expired which could lead to old or invalid signed boot components being loaded. |
| ZF FROST is a Rust implementation of FROST (Flexible Round-Optimised Schnorr Threshold signatures). In versions 2.0.0 through 2.1.0, refresh shares with smaller min_signers will reduce security of group. The inability to change min_signers (i.e. the threshold) with the refresh share functionality (frost_core::keys::refresh module) was not made clear to users. Using a smaller value would not decrease the threshold, and attempts to sign using a smaller threshold would fail. Additionally, after refreshing the shares with a smaller threshold, it would still be possible to sign with the original threshold, potentially causing a security loss to the participant's shares. This issue is fixed in version 2.2.0. |
| NeuVector used a hard-coded cryptographic key embedded in the source
code. At compilation time, the key value was replaced with the secret
key value and used to encrypt sensitive configurations when NeuVector
stores the data. |
| ci solution CI-Out-of-Office Manager through 6.0.0.77 uses a Hard-coded Cryptographic Key. |
