Despite a recent patch, many versions remain at risk of remote code execution, posing significant threats to systems, especially those running outdated software. Immediate actions such as upgrading to version 6.4.0 and implementing new security mechanisms are advised to mitigate risks. ## Content # Critical Apache Struts 2 Vulnerability CVE-2024-53677 Under Active Exploitation A critical vulnerability in Apache Struts 2, identified as CVE-2024-53677, is currently under active exploitation. Despite a patch being released last week, multiple versions of Struts remain vulnerable, putting numerous systems at significant risk of remote code execution (RCE) under certain conditions. ## Details of the Vulnerability The vulnerability, which affects various versions of the Apache Struts 2 framework, has a high CVSS score of 9.5, indicating its severity. It allows attackers to execute remote code, potentially leading to full system compromise. This flaw is reminiscent of an earlier vulnerability, CVE-2023-50164, though CVE-2024-53677 presents new challenges due to its complexity and the agedness of the framework. ## Impact and Challenges Organizations relying on outdated versions of Apache Struts are particularly vulnerable. The fix for CVE-2024-53677 is not straightforward, necessitating code rewrites and significant manual intervention, especially for older applications. This makes the task daunting for IT teams, who must ensure that their systems are secured against this threat. The widespread legacy usage of Struts 2 in critical sectors such as finance, insurance, and government exacerbates the issue. ## Recommended Actions The cybersecurity agencies of various countries, including the Australian Cyber Security Center (ACSC), have issued warnings and immediate action recommendations: - **Upgrade to Apache Struts 2 Version 6.4.0 or Later:** The patch for this vulnerability is available in version 6.4.0, and users are strongly advised to update their systems. - **Adopt New Security Mechanisms:** Implement the new Action File Upload mechanism provided in the latest release to mitigate potential risks. - **Continuous Monitoring and Auditing:** Regularly monitor and audit IT systems for suspicious activities to detect and respond to exploitation attempts promptly. - **Implement Robust Lifecycle Management:** Establishing a clear plan for regular updates and maintenance of software can help organizations manage and mitigate such vulnerabilities effectively. ## Conclusion CVE-2024-53677 is a critical vulnerability that requires immediate attention and action. By upgrading to the latest version of Apache Struts 2 and adopting recommended security measures, organizations can safeguard their IT infrastructures and prevent potential exploits that could lead to severe security breaches. ## Community discussion Top comments from developers on daily.dev. **@dekeoma** · 0 upvotes > damn this AI generated post...psst ## Similar posts on daily.dev - [Don’t just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) · CNCF · 1 upvotes · 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) · CNCF · 1 upvotes · 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) · CNCF · 0 upvotes · 0 comments - [CNCF Unveils Schedule for KubeCon \+ CloudNativeCon Europe 2026](https://daily.dev/posts/cncf-unveils-schedule-for-kubecon-cloudnativecon-europe-2026-ikhcoa5cb) · CNCF · 2 upvotes · 0 comments - [CNCF Debuts KubeCon \+ CloudNativeCon Japan 2026 Schedule](https://daily.dev/posts/cncf-debuts-kubecon-cloudnativecon-japan-2026-schedule-xp5pyudub) · CNCF · 1 upvotes · 0 comments --- Tags: [#cyber](https://daily.dev/tags/cyber), [#vulnerability](https://daily.dev/tags/vulnerability) [View this post on daily.dev](https://daily.dev/posts/critical-apache-struts-2-vulnerability-cve-2024-53677-under-active-exploitation-e3kau0lpt) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Critical Apache Struts 2 Vulnerability CVE-2024-53677 Under Active Exploitation","url":"https://daily.dev/posts/critical-apache-struts-2-vulnerability-cve-2024-53677-under-active-exploitation-e3kau0lpt","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/critical-apache-struts-2-vulnerability-cve-2024-53677-under-active-exploitation-e3kau0lpt"},"datePublished":"2024-12-19T18:32:56.864Z","dateModified":"2024-12-19T18:34:33.215Z","description":"CVE-2024-53677, a critical vulnerability in Apache Struts 2, is currently being actively exploited.
