Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

CISA Malcolm是美国CISA政府部门开源的一款面向威胁情报与安全审计的网络流量分析工具。 CISA Malcolm v26.06.0之前版本存在路径遍历漏洞，该漏洞源于接受认证用户上传文件的接口在解压归档文件时未验证解压路径是否位于目标目录内，可能导致经过身份验证的攻击者利用特制归档文件将文件写入任意位置，从而向系统存储数据中注入伪造记录或篡改应用程序配置。

Vulnerability Title
Path Traversal in Malcolm
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.
