CVE-2016-5752

Status: ModifiedHigh (7.5)—

The SAML2 implementation in Identity Server in NetIQ Access Manager 4.1 before 4.1.2 HF1 and 4.2 before 4.2.2 was handling unsigned SAML requests incorrectly, leaking results to a potentially malicious "Assertion Consumer Service URL" instead of the original requester.

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).
