CVE-2025-66034-htb-ctf
CVE-2025-66034-htb-ctf VariaType 可变字体生成器漏洞利用工具 此仓库包含针对 Hack The Box 上 VariaType 机器的专用漏洞利用工具。该漏洞利用利用了 fontTools 库或 Web 应用程序处理 .designspace XML 文件和元数据插值时的漏洞，以实现远程代码执行 RCE 。 📝 描述 该漏洞存在于字体生成过程中。通过构造恶意的 designspace 文件，我们可以将 PHP 反向 shell 载荷注入到字体的元数据中（特别是 字段）。当服务器处理这些文件以生成可变字体时，它会将输出写入用户定义的路径，从而允许我们将 .p...
