Title

IBM WebSphere eXtreme Scale服务端请求伪造漏洞

Description

IBM WebSphere eXtreme Scale是美国IBM公司的一个弹性数据缓存和对象网格平台。 IBM WebSphere eXtreme Scale存在服务端请求伪造漏洞，该漏洞源于对ogclient.jar中约50个CORBA存根类进行Java反序列化时，攻击者可利用该漏洞控制IOR字符串上调用ORB.string_to_object()，可将WAS中任何未过滤的ObjectInputStream接收点转化为针对攻击者选定主机的出站IIOP SSRF；当与IBM ORB的getUserException类实例化缺陷（WAS-26）结合使用时，此SSRF升级为在调用JVM上执行远程代码。

Vulnerability from cvelistv5 – Published: 2026-06-30 19:20 – Updated: 2026-06-30 19:37

Title

IBM WebSphere eXtreme Scale is affected by server side request forgery when ORB is used as Transport Protocol

Summary

IBM WebSphere Extreme Scale 8.6.1.0 through 8.6.1.6 Approximately 50 generated CORBA stub classes in WebSphere eXtreme Scale's ogclient.jar call ORB.string_to_object() on an attacker-controlled IOR string during Java deserialization, turning any unfiltered ObjectInputStream sink in WAS into outbound IIOP SSRF to an attacker-chosen host; when chained with the IBM ORB's getUserException class-instantiation flaw (WAS-26), this SSRF escalates to remote code execution on the calling JVM.
