Cisco has released software updates to address four security vulnerabilities in its software that could be weaponized by malicious actors to take control of affected systems. The most critical of the flaws is  CVE-2022-20650  (CVSS score: 8.8), which relates to a command injection flaw in the NX-API feature of Cisco NX-OS Software that stems from a lack of sufficient input validation of user-supplied data. "An attacker could exploit this vulnerability by sending a crafted HTTP POST request to the NX-API of an affected device," Cisco said. "A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the underlying operating system." The flaw impacts Nexus 3000 Series Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, and Nexus 9000 Series Switches in standalone NX-OS mode running Cisco NX-OS Software that have the NX-API feature enabled. Also patched are two high-severity den...

Cybersecurity researchers with Qihoo 360's NetLab today unveiled details of two recently spotted zero-day cyberattack campaigns in the wild targeting enterprise-grade networking devices manufactured by Taiwan-based DrayTek. According to the report , at least two separate groups of hackers exploited two critical remote command injection vulnerabilities ( CVE-2020-8515 ) affecting DrayTek Vigor enterprise switches, load-balancers, routers and VPN gateway devices to eavesdrop on network traffic and install backdoors. The zero-day attacks started somewhere at the end of last November or at the beginning of December and are potentially still ongoing against thousands of publicly exposed DrayTek switche s, Vigor 2960, 3900, 300B devices that haven't yet been patched with the latest firmware updates released last month. The zero-day vulnerabilities in question can be exploited by any unauthorized remote attackers to inject and execute arbitrary commands on the system, as als...
