Barracuda confirms attackers are exploiting Email Security Gateway flaws Barracuda has confirmed that attackers are exploiting two vulnerabilities in its Email Security Gateway, flaws that can be chained to give an attacker root control of the appliance. According to BleepingComputer, Barracuda updated its advisory Monday to say exploitation has hit a small number of organizations. The company hasn’t said who is behind the attacks. The flaws are CVE-2026-116606, an authentication weakness that lets an attacker modify the appliance’s global configuration, and CVE-2026-111560, a command injection bug in the timezone setting that runs commands as root. The command injection flaw also affects Barracuda’s Load Balancer ADC, Message Archiver, WAF Control Center, Web Application Firewall and Web Security Gateway products. Barracuda released patches about a week before confirming the attacks, and says some customers may already have them through automatic patching. SecurityWeek covered the flaws on November 4, based on Mandiant advisories, and rated the authentication bypass 9.3 and the command injection 8.6 on the CVSS scale. At that point, neither advisory reported exploitation. The sources also differ on one detail: Barracuda says administrative interface access is required for both bugs, while Mandiant says the authentication bypass can be exploited without authentication. For MSPs that manage or resell Barracuda appliances, start with an inventory. Confirm the right patch is installed on every affected product, turn automatic patching back on if it was disabled, and restrict admin interfaces to trusted internal networks, as Barracuda recommends. Because the flaws are being exploited, check devices for signs of compromise rather than assuming a patch settles it. SecurityWeek notes ESG appliances have been targeted before, by Chinese cyberspies exploiting a 2023 flaw, so tell customers what you checked. Hatz AI raises $24M as its MSP partner network triples Hatz AI, the platform that helps managed service providers sell and govern AI for their customers, has raised a $24 million Series A as its partner network grows. Channel Insider reports the round was led by Josh Schertzer, a partner at Nadia Partners and former Blackstone CTO, with participation from Vestigo Ventures and The Private Shares Fund. Hatz says its active MSP partner count tripled year over year and revenue grew even faster. Headcount has gone from 14 to nearly 60, and the partner network spans thousands of MSPs across all 50 U.S. states, nine Canadian provinces and nine countries. Hatz positions its platform as an “AI control plane” that lets MSPs deliver branded AI services while managing security, governance, spending and access to multiple foundation models. The company says it has issued more than 15,000 AI certifications. Its Activate offering, launched in August, helps providers assess customer AI readiness and spot shadow AI risk, and Hatz Spaces, launched earlier this month, adds collaborative AI workspaces under MSP-managed controls. The new money will go toward automated model routing, benchmarking, engineering infrastructure and expanding its forward-deployed engineering, research and optimization teams. “By giving MSPs full control over governance, spend, and deployment,” CEO and co-founder Jimmy Hatzell said, small businesses can become AI native. For solution providers, the funding is one more sign that managed AI is becoming a category of its own. Channel Insider cites Informa’s 2026 MSP 501 research, in which 57 percent of MSPs expect AI to be among their largest revenue growth areas in the next year, but also Nerdio research finding only 12 percent reported measurable productivity gains from AI. If you’re weighing a platform, ask how it handles governance and who owns the customer relationship. Attackers exploit Xen Orchestra flaw to take over XCP-ng hosts Attackers are exploiting a critical authentication bypass in Xen Orchestra, the management console for XCP-ng virtualization hosts, and a second related flaw has no fix yet. BleepingComputer reports that Vates, the project’s maintainer, tracks the bug as VSA-2026-062. It has no CVE identifier or CVSS score yet. A remote attacker with network access to the management interface can send a crafted authentication cookie containing an empty JSON object and be logged in as the owner of an existing token, with no credentials. From there, Vates warns, an attacker can act with admin privileges, run code on managed pools and take over an XCP-ng node as root. The flaw was reported by Filip Magic and Christoffer Olsen of TDC NET Security. Vates has confirmed active exploitation and published indicators of compromise, including connections to a specific IP address, a virtual machine named “pivot2,” VMs set to file-based serial output, and several cron files on hosts. The Hacker News notes that VirusTotal flags the IP as a RedLine Stealer command-and-control server, that it’s unclear when the activity began, and that a related flaw, VSA-2026-063, is reportedly used alongside it. That second bug lets a privileged user upload a crafted VM image to compromise a host, and no fix was available at the time of reporting. Fixed versions are Xen Orchestra 6.9.1 and 6.10.0, or xo-server 5.211.2 and 5.213.1. For MSPs and VARs running XCP-ng, whether for their own infrastructure or for customers weighing alternatives to VMware, update now, restrict the console to a dedicated management network, and hunt for the listed indicators. Vates says exploitation leaves no trace in logs, so watch HTTP traffic for the crafted cookie, and rotate secrets if you suspect compromise. In The Channel: If you missed it, Huntress and Ingram Micro executives were on yesterday’s episode: How Huntress and Ingram Micro plan to grow the Canadian MSP security market Read Full Transcript Welcome to The Buzz for Friday, November 13, 2026. I’m Robert Dutt, and here’s what’s happening in the channel today. If you manage or resell Barracuda gear, today’s top story needs your attention. Barracuda has confirmed that attackers are exploiting two flaws in its Email Security Gateway. Plus, Hatz AI has raised twenty-four million dollars for its MSP artificial intelligence platform, and attackers are taking over virtualization hosts through a flaw in Xen Orchestra. Up first, Barracuda has confirmed attacks on two vulnerabilities in its Email Security Gateway, and together they can give an attacker root control of the appliance. BleepingComputer reports that Barracuda updated its advisory on Monday to say a small number of organizations have been hit. The company hasn’t said who is behind the attacks. One flaw is an authentication weakness that lets an attacker change the appliance’s global configuration. The other is a command injection bug in the timezone setting that runs commands as root. That second flaw also affects Barracuda’s load balancer, message archiver, web application firewall and web security gateway products. Barracuda released patches about a week before it confirmed the attacks, and says some customers may already have them through automatic patching. SecurityWeek covered the flaws on November fourth, based on advisories from Mandiant, and at that point nobody had reported exploitation. The sources also disagree on one detail. Barracuda says an attacker needs access to the administrative interface for both bugs, while Mandiant says the authentication bypass can be exploited without logging in. So what should you do? If you manage or resell Barracuda appliances, start with an inventory. Confirm the right patch is on every affected product, turn automatic patching back on if it was disabled, and limit admin interfaces to trusted internal networks, as Barracuda recommends. And because these flaws are being exploited, check the devices for signs of compromise instead of assuming the patch settles it. SecurityWeek notes these gateways have been targeted before, by Chinese cyberspies using a twenty twenty-three flaw, so tell your customers what you checked. Next, Hatz AI has raised a twenty-four million dollar Series A as its partner network grows. Channel Insider reports the round was led by Josh Schertzer, a partner at Nadia Partners and a former Blackstone CTO, with Vestigo Ventures and The Private Shares Fund also taking part. Hatz says its active MSP partner count tripled over the past year, and revenue grew even faster. The company has gone from fourteen employees to nearly sixty, and says its network spans thousands of MSPs across all fifty U.S. states, nine Canadian provinces and nine countries. Hatz describes its platform as an “AI control plane,” a way for MSPs to deliver branded AI services while managing security, governance, spending and access to multiple AI models. It says it has issued more than fifteen thousand AI certifications. The new money is earmarked for automated model routing, benchmarking, engineering infrastructure, and more forward-deployed engineers. CEO and co-founder Jimmy Hatzell said that giving MSPs full control over governance, spend and deployment makes it possible for small businesses to become, in his words, AI native.
