CWE-780: Use of RSA Algorithm without OAEP

VariantIncompleteExploit Likelihood: Medium

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

Extended Description

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.

Frequently Asked Questions

What is CWE-780: Use of RSA Algorithm without OAEP?+

CWE-780: Use of RSA Algorithm without OAEP is a Common Weakness Enumeration (CWE) entry maintained by MITRE. 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.

What are the security consequences of Use of RSA Algorithm without OAEP?+

If exploited, CWE-780 (Use of RSA Algorithm without OAEP) it can compromise Access Control, leading to outcomes such as Bypass Protection Mechanism.

What is the difference between a CWE and a CVE?+

A CWE (Common Weakness Enumeration) like CWE-780 describes a category of software weakness — the underlying flaw type. A CVE (Common Vulnerabilities and Exposures) identifies a specific, real-world vulnerability in a particular product. In short, a CWE is the kind of mistake, and a CVE is an instance of that mistake being found in software.
