3 CVEs Expose Critical Flaws in Legacy Apache Struts Apps

Legacy Apache Struts remains embedded in thousands of enterprise apps, but CVEs have not disappeared just because support ended. In 2025 alone, three new CVEs impacting Struts (54656, 48976, and 48734) highlight how unsupported versions are becoming a magnet for attackers.

If your application is still running Struts 1.x or 2.x, these vulnerabilities expose you to serious risks—including denial-of-service, log injection, and potential remote code execution. And since these versions are end-of-life, official fixes don’t exist.

That’s where HeroDevs comes in.

The 2025 CVEs You Shouldn’t Ignore

‍

CVE‑2025‑54656 – Log Injection via LookupDispatchAction

Struts Extras (pre-2.x) lets attackers forge log entries via malicious input. The result? Misleading logs that can blind your monitoring and incident response teams. No official fix from Apache.

CVE‑2025‑48976 – File Upload DoS via Commons FileUpload

Struts 1 uses Commons FileUpload by default—and it doesn’t enforce limits on multipart headers. Attackers can crash your server with oversized requests, exploiting memory exhaustion.

CVE‑2025‑48734 – Enum-Based Classloader Access

A flaw in Commons BeanUtils (used by Struts) allows attackers to bypass security controls and access internal Java classes—potentially enabling remote code execution in vulnerable environments.

Why This Matters for Legacy Struts Apps

These vulnerabilities hit frameworks that are no longer maintained by the Apache community. If you’re stuck on Struts due to application complexity, you’re effectively running unpatchable software.

Attackers know this.
