Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2013-2566
CWEhttps://cwe.mitre.org/data/definitions/326.html

The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext.

Weakness

The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
