Quick assessment

Affected
OpenIdentityPlatform OpenAM
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

16.1.4 版本之前的 OpenAM 及其客户端 SDK 未能对内部服务器到服务器的 SOAP 通道中的响应进行充分验证，使得处于网络中间位置的攻击者能够破坏系统的完整性和可用性。拦截未加密流量或控制站点服务器的攻击者，可导致接收进程崩溃、篡改可写文件，甚至可能执行恶意代码。
