CAPEC 描述
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
CAPEC 資訊
前置條件
Recipient is using a weak cryptographic signature verification algorithm or a weak implementation of a cryptographic signature verification algorithm, or the configuration of the recipient's application accepts the use of keys generated using cryptographically weak signature verification algorithms.所需技能
Cryptanalysis of signature verification algorithmReverse engineering and cryptanalysis of signature verification algorithm implementation
緩解措施
Use programs and products that contain cryptographic elements that have been thoroughly tested for flaws in the signature verification routines.相關弱點
| 弱點名稱 | |
|---|---|
CWE-347 |
Improper Verification of Cryptographic Signature The product does not verify, or incorrectly verifies, the cryptographic signature for data. |
CWE-327 |
Use of a Broken or Risky Cryptographic Algorithm The product uses a broken or risky cryptographic algorithm or protocol. |
CWE-295 |
Improper Certificate Validation The product does not validate, or incorrectly validates, a certificate. |
