not properly delimit the\nintended arguments, options, or switches within that command string.","When creating commands using interpolation into a string, developers may assume that only the arguments\u002Foptions that they specify will be processed.  This assumption may be even stronger when the programmer has encoded the command in a way that prevents separate commands from being provided maliciously, e.g. in the case of shell metacharacters.  When constructing the command, the developer may use whitespace or other delimiters that are required to separate arguments when the command. However, if an attacker can provide an untrusted input that contains argument-separating delimiters, then the resulting command will have more arguments than intended by the developer.  The attacker may then be able to change the behavior of the command.  Depending on the functionality supported by the extraneous arguments, this may have security-relevant consequences.","Draft","Base","Simple",1,false,[],{"title":165,"metaDescription":166,"keywords":167,"canonicalUrl":168,"structuredData":169},"What is CVE-2018-19518?
