Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Arbitrary File Upload in WP Symposium. π₯ **Consequences**: Attackers upload executable files (e.g., PHP shells) and execute arbitrary code on the server. This leads to full server compromise.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Flaw in `UploadHandler.php`. β **CWE**: The provided data lists `CWE_ID` as `null`, but the flaw is clearly **Improper Input Validation** allowing malicious file extensions.
