Summary
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.
