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...

Incorrect MAC key used in the RC4-MD5 ciphersuite

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.
