Secure Hash Algorithm 1: The Secure Hash Algorithm 1 has been proven to be vulnerable to chosen-prefix collision attacks as of 2019 (cf. sha-mbles.github.io).
The Secure Hash Algorithm 1 has been proven to be vulnerable to collision attacks as of 2017 (cf. shattered.io).
Cipher Block Chaining: The CBC mode is vulnerable to plain-text attacks with TLS 1.0, SSL 3.0 and lower. However a real fix is implemented with TLS 1.2 in which the GCM mode was introduced and which is not vulnerable to the BEAST attack. GCM should be preferred over CBC (cf. BEAST).
Secure Hash Algorithm 1 MAC: The Secure Hash Algorithm 1 has been proven to be vulnerable to chosen-prefix collision attacks as of 2019 (cf. sha-mbles.github.io). While this does not affect its usage as a MAC, safer alternatives such as SHA-256, or SHA-3 should be considered.
