Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 4.5.0 之前的 Photo Gallery, Sliders, Proofing and WordPress 插件中，对从上传的压缩包中提取的文件扩展名的验证存在缺陷。由于代码中错误地复用了某个变量作为循环计数器，导致扩展名检查总是通过。这使得被授予相册管理权限的用户可以在 Web 可访问的目录中写入任意文件；在会执行这些文件的服务器上，攻击者可以借此运行任意代码，实现远程代码执行。

Vulnerability Title
NextGEN Gallery < 4.5.0 - Authenticated Arbitrary File Upload via ZIP Import
Source: CVE Program / CVE List V5
Vulnerability Description
The Photo Gallery, Sliders, Proofing and WordPress plugin before 4.5.0 does not correctly validate the extensions of files extracted from an uploaded archive, due to a variable being reused as a loop counter so that the check always passes, allowing users granted its gallery-management capability by an administrator to write arbitrary files into a web-accessible directory and, on hosts that execute them, run arbitrary code.
