EUVD Vulnerability Catalog
EUVD-2006-4327
Severity: CRITICAL
Base Score: 9.1
CVSS Version: 3.1
Vulnerability Description
A flaw was found in OpenSSL. When configured to use an RSA key with exponent 3, OpenSSL improperly removes PKCS-1 padding before generating a hash. This allows remote attackers to forge PKCS #1 v1.5 signatures. Consequently, OpenSSL may incorrectly verify X.509 and other certificates, leading to a bypass of trust and authentication mechanisms.
