CVE-2020-8300
Citrix ADC and Citrix/NetScaler Gateway before 13.0-82.41, 12.1-62.23, 11.1-65.20 and Citrix ADC 12.1-FIPS before 12.1-55.238 suffer from improper access control allowing SAML authentication hijack through a phishing attack to steal a valid user session.
Does this matter?
Lower severity and a low EPSS score (3.00%). Track it; it rarely justifies an emergency change on its own.
