aria2c accepts a server certificate with incorrect Extended Key Usage (EKU). If the attackers compromise a certificate (with the associated private key) issued for a different purpose, they may be able to reuse it for TLS server authentication.
Weakness
The product does not validate, or incorrectly validates, a certificate.
