# Apache Struts file upload logic is flawed Advisory record · `GHSA-43mq-6xmg-29vm` - **Identifiers:** `GHSA-43mq-6xmg-29vm` · `CVE-2024-53677` - **State:** Confirmed - **Severity:** CVSS 9.5 Critical - **Critical:** Yes: CVSS 9+, CVSS 7+ and EPSS - **Weakness (CWE):** [CWE-22](https://cwe.mitre.org/data/definitions/22.html) · [CWE-434](https://cwe.mitre.org/data/definitions/434.html) · [CWE-915](https://cwe.mitre.org/data/definitions/915.html) - **Tags:** [Path traversal](https://agentprime.io/advisories/tag/path-traversal.md) · [Unrestricted file upload](https://agentprime.io/advisories/tag/file-upload.md) · [Broken access control](https://agentprime.io/advisories/tag/access-control.md) - **Published:** 11 Dec 2024 - **Updated:** 15 Jul 2025 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 11 Dec 2024, 18:30 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Critical Critical, because: - CVSS score 9.5: 9.0 or more. - CVSS score 9.5 (7.0 or more) and EPSS 0.72 (0.1 or more): a high score and a real chance of exploitation in the next 30 days. How we decide what’s critical: ## Affected packages - `org.apache.struts:struts2-core` (Maven): affected `<6.4.0`; fixed in `6.4.0` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > Apache Struts 2 (package org.apache.struts:struts2-core, versions from 2.0.0 before 6.4.0) is vulnerable to flawed file upload logic. An attacker can manipulate file upload parameters to traverse paths and, under some circumstances, upload a malicious file that enables remote code execution. Upgrade to version 6.4.0 or later; applications not using the older FileUploadInterceptor-based upload logic are not affected.

Once a person has reviewed it, this page will say what’s vulnerable, what has to be true for your app to be affected, and how to check. ## Severity and exploitation - 9.5 Critical, CVSS 4.0: `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`, from CNA (apache) - **CISA KEV:** Not listed. - **EPSS:** 0.72, the 99th percentile, on 14 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 11 Dec 2024, 15:35 UTC: [Confirmed by the CVE List](https://www.cve.org/CVERecord?id=CVE-2024-53677) - 11 Dec 2024, 16:15 UTC: [Confirmed by NVD](https://nvd.nist.gov/vuln/detail/CVE-2024-53677) - 31 Oct 2026, 15:10 UTC: First seen by agentprime - 31 Oct 2026, 15:10 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-43mq-6xmg-29vm) ## Sources - [GitHub Advisory Database: GHSA-43mq-6xmg-29vm](https://github.com/advisories/GHSA-43mq-6xmg-29vm) - [OSV: GHSA-43mq-6xmg-29vm](https://osv.dev/vulnerability/GHSA-43mq-6xmg-29vm) - - - - - - - - - Facts on this page come from the GitHub Advisory Database (CC-BY 4.0), OSV and the other sources listed, as published. We don’t reproduce full advisory descriptions, which can contain exploit code. ## Check whether this affects you A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet. - With the agentprime MCP server (), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: - In a browser: reads your lockfile in the browser, never uploading it. - Whether it touches your code, with file and line: the Claude Code plugin, - As JSON: , or `POST https://api.agentprime.io/v1/match` with your packages () --- The web page: .
