CVE-2012-0738
IBM Security AppScan Enterprise before 8.6.0.2 and Rational Policy Tester before 8.5.0.3 do not validate X.509 certificates during scanning, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary certificate.
Does this matter?
Lower severity and a low EPSS score (0.59%). Track it; it rarely justifies an emergency change on its own.
