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":82,"name":83,"description":84,"extendedDescription":85,"status":86,"abstraction":87,"structure":80},"CWE-150","Improper Neutralization of Escape, Meta, or Control Sequences","The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as escape, meta, or control character sequences when they are sent to a downstream component.","As data is parsed, an injected\u002Fabsent\u002Fmalformed delimiter may cause the process to take unexpected actions.","Incomplete","Variant",[],{"title":90,"metaDescription":91,"keywords":92,"canonicalUrl":93,"structuredData":94},"What is CVE-2021-25310?
