SSL Anonymous Cipher Suites Supported vulnerability (CWE-310) is when secure sockets layer (SSL) uses cipher suites that do not authenticate the parties involved in a secure communication. According to the OWASP Testing Guide, this vulnerability allows attackers to perform man-in-the-middle attacks, allowing them to gain access to sensitive information or...
SSL Certificate Chain Contains RSA Keys Less Than 2048 bits is a type of cryptographic vulnerability (CWE-310) which occurs when an SSL certificate chain contains RSA keys that are less than 2048 bits in length. This type of vulnerability is particularly common in infrastructure environments and can lead to serious...
SSL Certificate Signed Using Weak Hashing Algorithm is a vulnerability associated with the cryptographic algorithm used to sign the SSL certificate. This vulnerability is categorized as CWE-327, which is defined as “the use of a weak cryptographic algorithm or its parameters for protecting sensitive data” (CWE, 2020). This specific vulnerability...
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...
