Description Preview

The RC4 algorithm, as implemented in the TLS and SSL protocols, exhibits biases that can be exploited by remote attackers to conduct plaintext-recovery attacks through statistical analysis of ciphertext in numerous sessions using the same plaintext. This vulnerability poses a significant risk to the confidentiality of data transmitted over affected protocols.

Overview

This vulnerability in the RC4 algorithm affects various products and versions, allowing attackers to potentially recover plaintext from encrypted communications. The bias in the algorithm makes it easier for malicious actors to exploit the weakness and compromise the confidentiality of sensitive information.

Remediation

To mitigate the risk associated with this vulnerability, it is recommended to disable the use of RC4 in TLS and SSL configurations and switch to more secure cryptographic algorithms. Additionally, software vendors should release patches or updates that address this vulnerability and encourage users to apply them promptly to protect their systems and data.
