This arbitrary file upload flaw can easily be used to execute arbitrary code. https://horizon3.ai/attack-research/attack-blogs/cisco-ios-xe-wlc-arbitrary-file-upload-vulnerability-cve-2025-20188-analysis/ Don't Call That "Protected" Method: Dissecting an N-Day vBulletin RCE A change in PHP 8.1 can expose methods previously expected to be “safe”. vBulletin fixed a related flaw about a year ago without explicitly highlighting the security impact of the fix. A blog post now exposed the flaw and provided exploit examples. We have seen exploit attempts against honeypots starting May 25th, two days after the blog was published. https://karmainsecurity.com/dont-call-that-protected-method-vbulletin-rce keywords: vbulletin; php; exploit; cisco; wlc; png;
