The vulnerability of the RC4-MD5 encryption algorithm in the OpenSSL library allows a attacker to execute a “man-in-the-middle” attack.

The vulnerability of the RC4-MD5 encryption algorithm in the OpenSSL library stems from the improper use of authenticated data as a MAC key. As a result, the MAC key becomes essentially predictable. Exploiting this vulnerability allows an attacker to execute a “man-in-the-middle” attack...

Decrypt Citrix NetScaler Config Secrets

This module takes a Citrix NetScaler ns.conf configuration file as input and extracts secrets that have been stored with reversible encryption. The module supports legacy NetScaler encryption RC4 as well as the newer AES-256-ECB and AES-256-CBC encryption types. It is also possible to decrypt...

CVE-2022-1434

The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipie...

Man-in-the-Middle (MitM)

openssl3 is vulnerable to man-in-the-middle MitM attacks. The vulnerability exists because implementing the RC4-MD5 cipher suite incorrectly uses the AAD data as the MAC key, allowing an attacker to perform a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL...
