remote code execution | Breaking Cybersecurity News | The Hacker News

A German security researcher has publicly disclosed details of a serious vulnerability in one of the most popular FTP server applications, which is currently being used by more than one million servers worldwide. The vulnerable software in question is ProFTPD , an open source FTP server used by a large number of popular businesses and websites including SourceForge, Samba and Slackware, and comes pre-installed with many Linux and Unix distributions, like Debian. Discovered by Tobias Mädel , the vulnerability resides in the mod_copy module of the ProFTPD application, a component that allows users to copy files/directories from one place to another on a server without having to transfer the data to the client and back. According to Mädel, an incorrect access control issue in the mod_copy module could be exploited by an authenticated user to unauthorizedly copy any file on a specific location of the vulnerable FTP server where the user is otherwise not allowed to write a file.

The same security vulnerabilities that were recently reported in Zoom for macOS also affect two other popular video conferencing software that under the hood, are just a rebranded version of Zoom video conferencing software. Security researchers confirmed The Hacker News that RingCentral, used by over 350,000 businesses, and Zhumu, a Chinese version of Zoom, also runs a hidden local web server on users' computers, just like Zoom for macOS. The controversial local web server that has been designed to offer an automatic click-to-join feature was found vulnerable to remote command injection attacks through 3rd-party websites. Security researcher Jonathan Leitschuh initially provided a proof-of-concept demonstrating how the vulnerable web server  could eventually allow attackers to turn on users laptop's webcam and microphone remotely. The flaw was later escalated to remote code execution attack by another security researcher, Karan Lyons , who has now published a new v

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica

The chaos and panic that the disclosure of privacy vulnerability in the highly popular and widely-used Zoom video conferencing software created earlier this week is not over yet. As suspected, it turns out that the core issue—a locally installed web server by the software—was not just allowing any website to turn on your device webcam, but also could allow hackers to take complete control over your Apple's Mac computer remotely. Reportedly, the cloud-based Zoom meeting platform for macOS has also been found vulnerable to another severe flaw (CVE-2019-13567) that could allow remote attackers to execute arbitrary code on a targeted system just by convincing users into visiting an innocent looking web-page. As explained in our previous report by Swati Khandelwal, the Zoom conferencing app contained a critical vulnerability ( CVE-2019-13450 ) that resides in the way its click-to-join feature is implemented, which automatically turns on users' webcam when they visit an in

Microsoft today released its monthly batch of software security updates for the July month to patch a total of 77 vulnerabilities, 14 are rated Critical, 62 are Important, and 1 is rated Moderate in severity. The July 2019 security updates include patches for various supported versions of Windows operating systems and other Microsoft products, including Internet Explorer, Edge, Office, Azure DevOps, Open Source Software, .NET Framework, Azure, SQL Server, ASP.NET, Visual Studio, and Exchange Server. Details of 6 security vulnerabilities, all rated important, were made public before a patch was released, none of which were found being exploited in the wild. However, two new privilege escalation vulnerabilities, one affects all supported versions of the Windows operating system, and the other affects Windows 7 and Server 2008, have been reported as being actively exploited in the wild. Both actively exploited vulnerabilities lead to elevation of privilege, one (CVE-2019-1132)

Okay, folks, it's time to update your Firefox web browser once again—yes, for the second time this week. After patching a critical actively-exploited vulnerability in Firefox 67.0.3 earlier this week, Mozilla is now warning millions of its users about a second zero-day vulnerability that attackers have been found exploiting in the wild. The newly patched issue ( CVE-2019-11708 ) is a "sandbox escape" vulnerability, which if chained together with the previously patched "type confusion" bug ( CVE-2019-11707 ), allows a remote attacker to execute arbitrary code on victims' computers just by convincing them into visiting a malicious website. Browser sandboxing is a security mechanism that keeps third-party processes isolated and confined to the browser, preventing them from damaging other sensitive parts of a computer's operating system.
