Title: Cisco patches high-severity vulnerabilities in some routers
Description: Cisco disclosed five vulnerabilities in its SD-WAN software, three of which are considered high severity. The security flaws leave several products open to exploitation, including some routers and network management systems. CVE-2020-3266 is the most severe of all with a CVSS score of 7.8. A local attacker could exploit the CLI utility in SD-WAN to inject arbitrary commands with root privileges. The company says there are no workarounds as of the release of these exploits, so users are encouraged to patch as soon as possible.
