This vulnerability is due to improper checks throughout the restart of certain system processes. An attacker could exploit this vulnerability by logging on to an affected device and executing certain CLI commands. A successful exploit could allow the attacker to execute arbitrary commands on the underlying OS as root.

not have direct access to the operating system, such as in web applications. Alternately, if the weakness occurs in a privileged program, it could allow the attacker to specify commands that normally would not be accessible, or to call alternate commands with privileges that the attacker does not have. The problem is exacerbated if the compromised process does not follow the principle of least privilege, because the attacker-controlled commands may run with special system privileges that increases the amount of damage.\nThere are at least two subtypes of OS command injection:\nFrom a weakness standpoint, these variants represent distinct programmer errors. In the first variant, the programmer clearly intends that input from untrusted parties will be part of the arguments in the command to be executed. In the second variant, the programmer does not intend for the command to be accessible to any untrusted party, but the programmer probably has not accounted for alternate ways in which malicious attackers can provide input.","Stable","Base","Simple",{"id":154,"name":155,"description":156,"extendedDescription":157,"status":158,"abstraction":151,"structure":152},"CWE-266","Incorrect Privilege Assignment","A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.","","Draft",2,false,[],{"title":163,"metaDescription":164,"keywords":165,"canonicalUrl":166,"structuredData":167},"What is CVE-2022-20855?
