CWE-780 – Use of RSA Algorithm without OAEP

rocco
Read Time:32 Second

Description

The software uses the RSA algorithm but does not incorporate Optimal Asymmetric Encryption Padding (OAEP), which might weaken the encryption.

Padding schemes are often used with cryptographic algorithms to make the plaintext less predictable and complicate attack efforts. The OAEP scheme is often used with RSA to nullify the impact of predictable common text.

Modes of Introduction:

– Architecture and Design

Likelihood of Exploit: Medium

 

Related Weaknesses

CWE-327

 

Consequences

Access Control: Bypass Protection Mechanism

Without OAEP in RSA encryption, it will take less work for an attacker to decrypt the data or to infer patterns from the ciphertext.
