CVE-2016-15033

29
FAUCET Score

CVE-2016-15033 describes an arbitrary file upload vulnerability in the Delete All Comments plugin for WordPress, affecting versions up to and including 2.0. This critical flaw stems from a lack of file type validation in the delete-all-comments.php file. With a CVSS score of 9.8, unauthenticated attackers can exploit this vulnerability over the network with low complexity to upload arbitrary files, potentially leading to remote code execution and full compromise of the affected system. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the high severity warrants immediate patching.
