CVE-2018-1509

Status: ModifiedHigh (7.4)—

IBM Security Guardium EcoSystem 10.5 does not validate, or incorrectly validates, a certificate.This weakness might allow an attacker to spoof a trusted entity by using a man-in-the-middle (MITM) attack. The software might connect to a malicious host while believing it is a trusted host, or the software might be deceived into accepting spoofed data that appears to originate from a trusted host. IBM X-Force ID: 141417.

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).
