CVSS: 10.0EPSS: 97%CPEs: 54EXPL: 2CVE-2020-9054 – Zyxel Multiple NAS Devices OS Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2020-9054
Multiple ZyXEL network-attached storage (NAS) devices running firmware version 5.21 contain a pre-authentication command injection vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable device. ZyXEL NAS devices achieve authentication by using the weblogin.cgi CGI executable. This program fails to properly sanitize the username parameter that is passed to it. If the username parameter contains certain characters, it can allow command injection with the privileges of the web server that runs on the ZyXEL device. Although the web server does not run as the root user, ZyXEL devices include a setuid utility that can be leveraged to run any command with root privileges. • https://github.com/darrenmartyn/CVE-2020-9054 https://cwe.mitre.org/data/definitions/78.html https://kb.cert.org/artifacts/cve-2020-9054.html https://kb.cert.org/vuls/id/498544 https://krebsonsecurity.com/2020/02/zyxel-fixes-0day-in-network-storage-devices https://www.zyxel.com/support/remote-code-execution-vulnerability-of-NAS-products.shtml • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
