CVE-2019-9212

CWE-184Published: February 27, 2019· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

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
