CVE-2005-2946

7.5 HIGH 0.8% exploit odds Fix listed

What it is

The default configuration on OpenSSL before 0.9.8 uses MD5 for creating message digests instead of a more cryptographically strong algorithm, which makes it easier for remote attackers to forge certificates with a valid certificate authority signature.

Exploitability: Can be exploited over the network without logging in. High risk of data tampering.
Exploit odds: 0.8% chance of exploitation in the next 30 days (EPSS).
