Root Cause Analysis
The vulnerability stems directly from the line '$objProfileArray = unserialize(base64_decode($_POST['strProfileData']));' in profile.php. PHP's unserialize() with user-controlled input is a well-known anti-pattern (CWE-502). The function: 1) Processes raw POST input, 2) Lacks cryptographic signatures or type checks, 3) Exists in an unauthenticated endpoint. The patch in v3.2 adds profiling disable capability but the root vulnerability is the unsafe unserialize() call itself.
