Apache OFBiz 24.09（24.09.08 之前版本）在所有平台上存在 ServiceMultiEventHandler 中的资源消耗失控漏洞。该漏洞允许远程未认证攻击者通过提交单个小型 HTTP 请求，利用多表单提交中用于编码行数的"o"后缀参数名，使服务器请求线程被固定（pin），执行攻击者指定数量的同步服务调用，最多可达有符号整数的最大值。其根本原因在于：UtilHttp.getMultiFormRowCount 从最大的此类后缀推导行数时未设置上限，而 ServiceMultiEventHand

Vulnerability Title
Apache OFBiz: Unbounded multi-form row count from a parameter name
Source: CVE Program / CVE List V5
Vulnerability Description
Uncontrolled Resource Consumption in ServiceMultiEventHandler in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker to pin a server request thread for an attacker-chosen number of synchronous service dispatches, up to the signed-integer maximum, by submitting a single small HTTP request whose parameter names encode a row count via the "o" suffix used by multi-form submissions, because UtilHttp.getMultiFormRowCount derives that count from the largest such suffix with no upper bound and ServiceMultiEventHandler.invoke then loops that many times calling dispatcher.runSync, with the request-map for getFinAccountTransRunningTotalAndBalances reaching this handler with no authentication or CSRF requirement on a stock deployment. Users are recommended to upgrade to version 24.09.08, which fixes this issue.
