→Detect exploitation attempts by inspecting POST requests to /ProgramFunctions/PortalPollsNotes.fnc.php that include the HTTP header 'X-Requested-With: XMLHttpRequest' and a 'votes' parameter containing SQL metacharacters (e.g., single quotes, double dashes, SQL keywords like CREATE/DROP/SELECT). ↗
→The injection is delivered via the 'votes' POST parameter as an array key (e.g., votes[<payload>]=1). WAF/IDS rules should parse array-key notation in POST bodies and apply SQL injection detection to both keys and values of the 'votes' parameter. ↗
→The vulnerable code path requires: votes is a POST array, X-Requested-With equals XMLHttpRequest, and the votes array is non-empty. All three conditions must be met for the injection to reach PortalPollsVote(). Alert on any POST to this endpoint with these conditions and SQL-like content in array keys. ↗

·The vulnerability is unauthenticated — no session or login cookie is required to reach the vulnerable endpoint, meaning perimeter controls relying on authentication state will not block exploitation. ↗
·The SQL injection payload is embedded in the array *key* of the votes parameter (not the value), which may bypass WAF/IDS rules that only inspect POST parameter values and not parameter names or array keys. ↗
