Cryptography / SSL Medium Strength Cipher Suites Supported (Sweet32)

Description

SSL Medium Strength Cipher Suites Supported (SWEET32) is a vulnerability in Cryptography that occurs in Infrastructure. The Common Weakness Enumeration (CWE) directory identifies this vulnerability as CWE-327, which suggests that the cryptographic algorithm used is too weak to protect the data it is intended to secure. According to the OWASP Testing Guide, SWEET32 can be identified by a server that is utilizing 64-bit block ciphers like 3DES.

Risk

The risk of this vulnerability is that an attacker can exploit the weak cipher and gain access to sensitive data. This can lead to financial losses, reputational damage, and data breaches. According to the OWASP Risk Rating Methodology, SWEET32 has a high risk rating of 8.5.

Solution

The solution to this vulnerability is to disable the use of 64-bit block ciphers like 3DES and enable the use of stronger encryption algorithms like AES. Additionally, the server should be configured to use TLS 1.2 or higher, as this provides stronger encryption.
