arbitrary code execution | Breaking Cybersecurity News | The Hacker News

A highly critical vulnerability has been discovered in the Cisco Systems' WebEx browser extension for Chrome and Firefox, for the second time in this year, which could allow attackers to remotely execute malicious code on a victim's computer. Cisco WebEx is a popular communication tool for online events, including meetings, webinars and video conferences that help users connect and collaborate with colleagues around the world. The extension has roughly 20 million active users. Discovered by Tavis Ormandy of Google Project Zero and Cris Neckar of Divergent Security, the remote code execution flaw (CVE-2017-6753) is due to a designing defect in the WebEx browser extension. To exploit the vulnerability, all an attacker need to do is trick victims into visiting a web page containing specially crafted malicious code through the browser with affected extension installed. Successful exploitation of this vulnerability could result in the attacker executing arbitrary code with th...

Security researchers have disclosed local zero day DLL hijacking vulnerabilities in several applications developed by Corel Software that could allow an attacker to execute arbitrary commands on victims' computer, potentially affecting more than 100 million users. The security holes were publicly disclosed by Marcos Accossatto from a vulnerability research firm Core Security after the vendor didn't respond to his private disclosure about the flaws. Corel develops wide range of products including graphics, photo, video and other media editing programs. According to the researcher, when a media file associated with one of the vulnerable Corel products is opened, the product also loads a specifically named DLL (Dynamic Link Library) file into memory if it's located in the same directory as the opened media file. These DLL files contain executable code which could allow an attacker to install malware on victims' computers by inserting malicious DLLs into the...

Most microsegmentation projects fail before they even get off the ground—too complex, too slow, too disruptive. But Andelyn Biosciences proved it doesn't have to be that way.  Microsegmentation: The Missing Piece in Zero Trust Security   Security teams today are under constant pressure to defend against increasingly sophisticated cyber threats. Perimeter-based defenses alone can no longer provide sufficient protection as attackers shift their focus to lateral movement within enterprise networks. With over 70% of successful breaches involving attackers moving laterally, organizations are rethinking how they secure internal traffic.  Microsegmentation has emerged as a key strategy in achieving Zero Trust security by restricting access to critical assets based on identity rather than network location. However, traditional microsegmentation approaches—often involving VLAN reconfigurations, agent deployments, or complex firewall rules—tend to be slow, operationally disrupt...
