CWE-780 - Use of RSA Algorithm without OAEP
- Abstraction:Variant
- Structure:Simple
- Status:Incomplete
- Release Date:2009-07-27
- Latest Modification Date:2023-06-29
Weakness Name
Use of RSA Algorithm without OAEP
Description
The product 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.
Common Consequences
Scope: Access Control
Impact: Bypass Protection Mechanism
Notes: Without OAEP in RSA encryption, it will take less work for an attacker to decrypt the data or to infer patterns from the ciphertext.
