Apache Ofbiz XML-RPC RCE漏洞-CVE-2023-49070

2020年，为修复 CVE-2020-9496 增加权限校验，存在绕过。2021年，增加 Filter 用于拦截 XMLRPC 中的恶意请求，存在绕过。2023年四月，彻底删除xmlrpc handler 以避免同类型的漏洞产生尽管主分支在四月份已经移除了XML-RPC组件，但在Apache OFBiz的正式发布版本中，仅最新版本18.12.10彻底废除了XML-RPC功能。

流量分析: 攻击者利用这个漏洞时，会发送包含用户名和密码的 HTTP 请求到 XML-RPC 接口。在网络流量中，这可能表现为对 /webtools/control/xmlrpc 的异常访问请求。

异常请求内容: 利用 Filter 绕过机制的请求可能包含不寻常的 URI 结构，如使用分号或路径穿越技术(./)。

特定的错误日志: 在尝试进行反序列化攻击时，可能会在日志中观察到相关错误或异常信息，尤其是与XML-RPC 组件相关的。
