CVE-2019-9212: Antfin Sofa-Hessian

Critical severity, CVSS 9.8. EPSS: 2.8% chance of exploitation in the next 30 days.

SOFA-Hessian through 4.0.2 allows remote attackers to execute arbitrary commands via a crafted serialized Hessian object because blacklisting of com.caucho.naming.QName and com.sun.org.apache.xpath.internal.objects.XString is mishandled, related to Resin Gadget. NOTE: The vendor doesn’t consider this issue a vulnerability because the blacklist is being misused. SOFA Hessian supports custom blacklist and a disclaimer was posted encouraging users to update the blacklist or to use the whitelist feature for their specific needs since the blacklist is not being actively updated

Affected products

• Antfin Sofa-Hessian: up to and including 4.0.2
