CVE-2026-90444

Quick assessment

Affected
CISA Malcolm
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.

该文件传输接口要求提供有效凭据，但未对攻击者控制的文件名中的 shell 元字符进行限制。随后，一个自动化进程会使用已上传文件的名称来构造并执行系统命令，这使得经过身份验证的攻击者能够嵌入并执行任意的操作系统命令，且拥有该进程的权限。这使攻击者能够读取和修改已摄入的日志数据，并可能为在内网中进一步渗透提供立足点。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
A file-transfer interface that requires valid credentials accepts attacker-controlled filenames without restricting shell metacharacters. An automated process later constructs and runs a system command using the uploaded file's name, allowing an authenticated attacker to embed and execute arbitrary operating system commands with the privileges of that process. This allows an attacker to read and modify ingested log data, and could provide a foothold for further movement within the internal network.
