RC4 Algorithm Vulnerability in TLS and SSL Protocols Affecting Oracle Products
CVE-2013-2566

5.9MEDIUM

Summary

The RC4 algorithm utilized in the TLS and SSL protocols exhibits significant single-byte biases, enabling remote adversaries to exploit this flaw through statistical analysis of ciphertext. This vulnerability facilitates plaintext-recovery attacks when a large number of sessions, utilizing the same plaintext, are analyzed. Consequently, affected Oracle products relying on these protocols are at heightened risk, demanding immediate attention to ensure robust encryption practices and mitigation strategies.
