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.

该漏洞的描述信息翻译如下： 一个接受已认证用户上传文件的接口，在解压上传的归档文件时，未验证解压后的文件路径是否仍位于预期的目标目录内。这允许已认证的恶意用户构造一个归档文件，其内部条目路径包含“路径穿越”（如包含 ），使得解压过程能以该进程权限将文件写入任意位置。攻击者可借此向系统存储数据中注入伪造的记录，或篡改应用程序的配置。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
An interface that accepts file uploads from authenticated users extracts the contents of uploaded archives without validating that extracted file paths remain within the intended destination directory. This allows an authenticated attacker to craft an archive whose entries traverse outside the destination directory, causing the extraction process to write files to arbitrary locations with the privileges of that process. This could allow an attacker to inject fabricated records into the system's stored data or tamper with application configuration.
