Citrix today released patches for multiple new security vulnerabilities affecting its Citrix Endpoint Management (CEM) , also known as XenMobile, a product made for enterprises to help companies manage and secure their employees' mobile devices remotely. Citrix Endpoint Management offers businesses mobile device management (MDM) and mobile application management (MAM) capabilities. It allows companies to control which apps their employees can install while ensuring updates and security settings are applied to keep business information protected. According to Citrix, there are a total of 5 vulnerabilities that affect on-premise instances of XenMobile servers used in enterprises to manage all apps, devices, or platforms from one central location. "Remediations have already been applied to cloud versions, but hybrid rights users need to apply the upgrades to any on-premises instance," the company sai d in a post today. If left unpatched and exploited successfully,...

If you haven't recently updated your Chrome, Opera, or Edge web browser to the latest available version, it would be an excellent idea to do so as quickly as possible. Cybersecurity researchers on Monday disclosed details about a zero-day flaw in Chromium-based web browsers for Windows, Mac and Android that could have allowed attackers to entirely bypass Content Security Policy (CSP) rules since Chrome 73. Tracked as CVE-2020-6519 (rated 6.5 on the CVSS scale), the issue stems from a CSP bypass that results in arbitrary execution of malicious code on target websites. According to PerimeterX, some of the most popular websites, including Facebook, Wells Fargo, Zoom, Gmail, WhatsApp, Investopedia, ESPN, Roblox, Indeed, TikTok, Instagram, Blogger, and Quora, were susceptible to the CSP bypass. Interestingly, it appears that the same flaw was also highlighted by Tencent Security Xuanwu Lab more than a year ago, just a month after the release of Chrome 73 in March 2019, but...

A security researcher earlier today publicly revealed details and proof-of-concept exploit code for an unpatched, critical zero-day remote code execution vulnerability affecting the widely used internet forum software vBulletin that's already under active exploitation in the wild. vBulletin is a widely used proprietary Internet forum software package based on PHP and MySQL database server that powers over 100,000 websites on the Internet, including Fortune 500 and Alexa Top 1 million companies websites and forums. In September last year, a separate anonymous security researcher publicly disclosed a then-zero-day RCE vulnerability in vBulletin , identified as CVE-2019-16759 , and received a critical severity rating of 9.8, allowing attackers to execute malicious commands on the remote server without requiring any authentication to log into the forum. A day after the disclosure of CVE-2019-16759, the vBulletin team released security patches that resolved the issue, but it t...

I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...

If you are using TeamViewer, then beware and make sure you're running the latest version of the popular remote desktop connection software for Windows. TeamViewer team recently released a new version of its software that includes a patch for a severe vulnerability ( CVE 2020-13699 ), which, if exploited, could let remote attackers steal your system password and eventually compromise it. What's more worrisome is that the attack can be executed almost automatically without requiring much interaction of the victims and just by convincing them to visit a malicious web page once. For those unaware, TeamViewer is a popular remote-support software that allows users to securely share their desktop or take full control of other's PC over the Internet from anywhere in the world. The remote access software is available for desktop and mobile operating systems, including Windows, macOS, Linux, Chrome OS, iOS, Android, Windows RT Windows Phone 8, and BlackBerry. Discovered b...

Popular video conferencing app Zoom has addressed several security vulnerabilities, two of which affect its Linux client that could have allowed an attacker with access to a compromised system to read and exfiltrate Zoom user data—and even run stealthy malware as a sub-process of a trusted application. According to cybersecurity researcher Mazin Ahmed , who presented his findings at DEF CON 2020 yesterday, the company also left a misconfigured development instance exposed that wasn't updated since September 2019, indicating the server could be susceptible to flaws that were left unpatched. After Ahmed privately reported the issues to Zoom in April and subsequently in July, the company issued a fix on August 3 (version 5.2.4). It's worth noting that for some of these attacks to happen, an attacker would need to have already compromised the victim's device by other means. But that doesn't take away the significance of the flaws. In one scenario, Ahmed uncov...

A United States regulator has fined the credit card provider Capital One Financial Corp with $80 million over last year's data breach that exposed the personal information of more than 100 million credit card applicants of Americans. The fine was imposed by the Office of the Comptroller of the Currency (OCC), an independent bureau within the United States Department of the Treasury that governs the execution of laws relating to national banks. According to a press release published by the OCC on Thursday, Capital One failed to establish appropriate risk management before migrating its IT operations to a public cloud-based service, which included appropriate design and implementation of certain network security controls, adequate data loss prevention controls, and effective dispositioning of alerts. The OCC also said that the credit card provider also left numerous weaknesses in its cloud-based data storage in an internal audit in 2015 as well as failed to patch security ...

Cybersecurity researchers today highlighted an evasive phishing technique that attackers are exploiting in the wild to target visitors of several sites with a quirk in domain names, and leverage modified favicons to inject e-skimmers and steal payment card information covertly. "The idea is simple and consists of using characters that look the same in order to dupe users," Malwarebytes researchers said in a Thursday analysis . "Sometimes the characters are from a different language set or simply capitalizing the letter 'i' to make it appear like a lowercase 'l'." Called an internationalized domain name (IDN) homograph attack , the technique has been used by a Magecart group on multiple domains to load the popular Inter skimming kit hidden inside a favicon file . The visual trickery typically involves leveraging the similarities of character scripts to create and register fraudulent domains of existing ones to deceive unsuspecting users into...
