A new vulnerability\u2014<strong>CVE-2025-24813<\/strong>\u2014has been found. And this isn\u2019t some obscure bug. It\u2019s one of those flaws that can give attackers full access to your systems, even without login credentials.<\/p>\n\n\n\n<p>This CVE is serious. It affects Tomcat environments running in <strong>Microsoft Hyper-V<\/strong> setups, including<a href=\"https:\/\/www.purewl.com\/is-cloud-computing-important-for-web-development\/\" target=\"_blank\" rel=\"noreferrer noopener\"> cloud-based deployments<\/a> that many businesses rely on for internal tools, customer apps, or admin portals.<\/p>\n\n\n\n<p>If you\u2019re running anything behind Tomcat\u2014even a simple dashboard\u2014you need to know what this vulnerability is, who it targets, and what you should be doing right now.<\/p>\n\n\n\n<p>Let\u2019s break it down in plain language.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_CVE-2025-24813\"><\/span>What Is CVE-2025-24813?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>CVE-2025-24813 is a <strong>remote code <\/strong><a href=\"https:\/\/www.purevpn.com\/white-label\/cve-2025-26633\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>execution vulnerability<\/strong><\/a> discovered in Apache Tomcat. It affects how Tomcat handles specific types of virtualized networking when used with Microsoft Hyper-V.<\/p>\n\n\n\n<p>In simple terms: someone can send crafted packets to a system running Tomcat, and they might be able to execute their own code on that machine. They don\u2019t even need to be logged in.<\/p>\n\n\n\n<p>This isn\u2019t just theoretical. It\u2019s already on the radar of security vendors and federal agencies. And given how widely Tomcat is used, the risk spreads fast across industries.<\/p>\n\n\n\n<p>This is one of those <strong>Apache Tomcat vulnerabilities<\/strong> that doesn\u2019t just affect developers\u2014it hits the infrastructure level. VPN servers, <a href=\"https:\/\/www.purewl.com\/industries\/saas-vendors\/\" target=\"_blank\" rel=\"noreferrer noopener\">SaaS apps<\/a>, customer-facing portals, and even internal HR systems can be exposed if they\u2019re built on Tomcat.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Tomcat_Why_Now\"><\/span>Why Tomcat? Why Now?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Apache Tomcat is everywhere. It\u2019s one of the most popular servlet containers in the world. It\u2019s lightweight, open-source, and used in thousands of apps.<\/p>\n\n\n\n<p>That makes it a favorite target.<\/p>\n\n\n\n<p>Combine that with the fact that many businesses don\u2019t update it regularly, and attackers see easy wins. This specific vulnerability ties into how Tomcat interacts with Hyper-V networking features\u2014something that\u2019s harder to secure unless you know it\u2019s a problem.<\/p>\n\n\n\n<p>And now? It\u2019s a problem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_CVE-2025-24813_Is_a_Big_Deal\"><\/span>Why CVE-2025-24813 Is a Big Deal?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>This isn\u2019t your average patch-and-move-on bug. <strong>CVE-2025-24813<\/strong> lets someone run code on your server from the outside.

They don\u2019t need to trick someone into clicking something. If your system is exposed, it\u2019s vulnerable.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Whos_Affected\"><\/span>Who\u2019s Affected?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Anyone running <strong>Apache Tomcat in a Hyper-V environment<\/strong>\u2014especially if you\u2019re using older versions or haven\u2019t applied patches in a while.<\/p>\n\n\n\n<p>It\u2019s not just enterprise IT teams that need to worry. VPN service providers, white-label resellers, hosting companies, and B2B SaaS startups all use Tomcat somewhere\u2014often without realizing it.<\/p>\n\n\n\n<p>Your customer portal, <a href=\"https:\/\/www.purevpn.com\/vpn-reseller\/can-there-be-multiple-users-for-a-vpn-reseller-dashboard\/\" target=\"_blank\" rel=\"noreferrer noopener\">admin dashboard<\/a>, or reporting server could be exposed without showing any signs.

According to multiple advisories, the issue impacts certain configurations running in Microsoft Hyper-V environments. If that\u2019s your setup, you can\u2019t assume you&#8217;re safe.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step_1_Check_Your_Version\"><\/span>Step 1: Check Your Version<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Log into your server and run:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code><strong><em>$ .\/catalina.sh version<\/em><\/strong><\/code><\/pre>\n\n\n\n<p>If the output shows an affected version (refer to Apache\u2019s official patch advisory), you\u2019ll need to dig deeper.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step_2_Review_Your_Environment\"><\/span>Step 2: Review Your Environment<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>This CVE only triggers in certain cases. Specifically, when Tomcat is paired with a specific Hyper-V virtual switch configuration. If you&#8217;re using NAT or Internal virtual networking, this risk may apply.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step_3_Scan_Your_Systems\"><\/span>Step 3: Scan Your Systems<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Use a vulnerability scanner like OpenVAS or Tenable. If you\u2019re running web servers with public exposure, even a basic Nmap script can give you clues. Look for open ports, version headers, and any unexpected behavior.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Fix_CVE-2025-24813_And_Fast\"><\/span>How to Fix CVE-2025-24813 (And Fast)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Here\u2019s how to patch the issue properly and avoid the fallout.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step_1_Apply_the_Official_Patch\"><\/span>Step 1: Apply the Official Patch<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The Tomcat development team has already released a fix. Download the latest version from the<a href=\"https:\/\/tomcat.apache.org\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"> Apache Tomcat website<\/a>. Install it across all affected environments.<\/p>\n\n\n\n<p>Avoid waiting for your package manager or OS vendor to catch up. In most cases, manual upgrades are faster.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step_2_Restart_and_Test\"><\/span>Step 2: Restart and Test<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Once the patch is in, restart your services. Then test everything\u2014especially <a href=\"https:\/\/www.purewl.com\/white-label-vpn\/\" target=\"_blank\" rel=\"noreferrer noopener\">custom apps built<\/a> on Tomcat. Look for any breaks or errors. If something doesn\u2019t work, check config files or library versions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step_3_Document_It\"><\/span>Step 3: Document It<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Track what you did, who did it, and when.

Use firewall rules to restrict Tomcat\u2019s exposure. Set up role-based access to the admin console. Use logging and alerts to catch strange behavior early.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Are_CVE_2025_24813_Vulnerabilities_Doing_in_the_Wild\"><\/span>What Are CVE 2025 24813 Vulnerabilities Doing in the Wild?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are early signs of <strong>CVE 2025 24813 vulnerabilities<\/strong> being tested in the wild. That means attackers are scanning the internet, looking for unpatched servers.<\/p>\n\n\n\n<p>SecurityWeek and ZDI have already published warnings about suspicious traffic tied to this flaw. While a full exploit chain hasn\u2019t been widely shared yet, the pattern is familiar\u2014attackers try known exploits shortly after public disclosure, hoping some systems haven\u2019t been updated.<\/p>\n\n\n\n<p>Don\u2019t be one of those systems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Apache_Tomcat_Vulnerability_History_This_Isnt_the_First\"><\/span>Apache Tomcat Vulnerability History: This Isn\u2019t the First<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Tomcat has a long history of being targeted.

But it\u2019s serious because of how it bypasses standard login barriers. This is the kind of flaw that can lead to full compromise, especially if you run backend tools on exposed ports.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Mistakes_That_Let_Vulnerabilities_Like_CVE-2025-24813_In\"><\/span>Mistakes That Let Vulnerabilities Like CVE-2025-24813 In<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Even businesses that take security seriously fall into the same traps.
