CVE-2019-9212

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

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
