ATutor ATutor
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.

ATutor 在 ZIP 文件提取功能中存在路径遍历漏洞。拥有讲师权限的攻击者可以上传并提取一个特制的 ZIP 归档文件，导致文件被写入到预期的解压目录之外。这使得攻击者能够在网站根目录下放置一个可由服务器执行的 .phtml 文件，从而在底层服务器上以 Web 服务器权限实现远程代码执行。 该产品已不再获得主动支持，且相关漏洞尚未修复。仅对 2.2.4 版本进行了测试并确认存在漏洞，其他版本未经测试，但也可能存在相同漏洞。

Vulnerability Title
Path Traversal leading to Remote Code Execution in ATutor
Source: CVE Program / CVE List V5
Vulnerability Description
ATutor is vulnerable to a Path Traversal vulnerability in ZIP extraction functionality. An attacker with instructor privileges can upload and extract a specially crafted ZIP archive, causing files to be written outside the intended extraction directory. This allows an attacker to place a server-executable .phtml file in the web root and achieve remote code execution with web server privileges on the underlying server. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.
