二、漏洞 CVE-2026-3395 的公开POC
| # | POC 描述 | 源链接 | 神龙链接 |
|---|---|---|---|
| 1 | MaxSite CMS through 109.1 allows unauthenticated remote attackers to execute arbitrary code via the MarkItUp editor preview AJAX endpoint, preview-ajax.php. The endpoint insufficiently authenticates the request, failing to ensure the user is logged in, and processes the attacker's input via unsafe usage of PHP eval() on user-supplied [php]...[/php] shortcodes. By providing a POST request to the vulnerable /ajax/ endpoint with crafted input, attackers may achieve remote code execution. The issue is addressed in version 109.2 by implementing proper authentication controls. | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-3395.yaml | POC详情 |
