CVE-2008-1198

Status: ModifiedHigh (7.1)—

The default IPSec ifup script in Red Hat Enterprise Linux 3 through 5 configures racoon to use aggressive IKE mode instead of main IKE mode, which makes it easier for remote attackers to conduct brute force attacks by sniffing an unencrypted preshared key (PSK) hash.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
