CVSS: 9.8EPSS: 0%CPEs: 11EXPL: 0CVE-2022-29841 – OS Command Injection vulnerability in Western Digital My Cloud devices
https://notcve.org/view.php?id=CVE-2022-29841
Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability that was caused by a command that read files from a privileged location and created a system command without sanitizing the read data. This command could be triggered by an attacker remotely to cause code execution and gain a reverse shell in Western Digital My Cloud OS 5 devices.This issue affects My Cloud OS 5: before 5.26.119. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Western Digital MyCloud PR4100 NAS devices. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the do_reboot binary. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. • https://www.westerndigital.com/support/product-security/wdc-23002-my-cloud-firmware-version-5-26-119 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
