In ModSecurity before 2.9.6 and 3.x before 3.0.8, HTTP multipart requests were incorrectly parsed and could bypass the Web Application Firewall. NOTE: this is related to CVE-2022-39956 but can be considered independent changes to the ModSecurity (C language) codebase.
Product A handles inputs or steps differently than Product B, which causes A to perform incorrect actions based on its perception of B’s state.
