golang.org/x/crypto/ssh Man-in-the-Middle attack

The Go SSH library golang.org/x/crypto/ssh by default does not verify host keys, facilitating man-in-the-middle attacks if ClientConfig.HostKeyCallback is not set. Default behavior changed in commit e4e2799 to require explicitly registering a hostkey verification mechanism...

Go SSH library vulnerable to Man-in-the-Middle attacks

The Go SSH library x/crypto/ssh by default does not verify host keys, facilitating man-in-the-middle attacks. Default behavior changed in commit e4e2799 to require explicitly registering a hostkey verification mechanism...

The vulnerability of the SSH library (x/crypto/ssh) in the Go programming language, which allows a hacker to execute a “man-in-the-middle” attack.

The vulnerability of the SSH library x/crypto/ssh in the Go programming language is related to data encryption errors. Exploiting this vulnerability can allow a remote attacker to execute a “man-in-the-middle” attack...

CVE-2022-29245

SSH.NET (Renci.SshNet) is affected by CVE-2022-29245 due to generating the private key during X25519 key exchange with System.Random in versions 2020.0.0 and 2020.0.1. The non-cryptographically secure RNG can have a brute-forceable seed, enabling an eavesdropper to potentially decrypt traffic dur...

CVE-2022-29245 Weak private key generation in SSH.NET

SSH.NET is a Secure Shell SSH library for .NET. In versions 2020.0.0 and 2020.0.1, during an X25519 key exchange, the client’s private key is generated with System.Random. System.Random is not a cryptographically secure random number generator, it must therefore not be used for cryptographic...

SSH.NET 安全特征问题漏洞

SSH.NET is an SSH library for .NET optimized for parallelism. A security signature issue vulnerability exists in SSH.NET versions 2020.0.0 and 2020.0.1, which stems from a client's private key being generated during an X25519 key exchange using System.Random. System.Random is not a...

golang.org/x/crypto: empty plaintext packet causes panic

There's an input validation flaw in golang.org/x/crypto's readCipherPacket function. An unauthenticated attacker who sends an empty plaintext packet to a program linked with golang.org/x/crypto/ssh could cause a panic, potentially leading to denial of service...
