有効/無効設定 このワーニングクラスのチェックはデフォルトで有効になっています。チェックを無効にするにはプロジェクト設定ファイル （configuration file）に以下の WARNING_FILTER ルールを追加してください。 
WARNING_FILTER += discard class="Command Injection"

例 

#include <stdlib.h>
#include <stdio.h>

int command_from_file(FILE *infile)
{
    char comm[80];
    char *res = fgets(comm, 80, infile);
    if (res)
        return system(comm); /* 'Command Injection' warning issued here */
    return -1;
}

ワーニングを引き起こす関数

CodeSonar ships with library models that allow it to a number of functions that use one or more of their parameters to construct an operating system command. If one of these functions is called with a tainted value in one of those parameter positions, a warning will be issued.

If you have created a custom library model for some function f() in terms of one of these existing models, calls to f() will also be capable of triggering Command Injection warnings.

Functions that can trigger warnings include...
gcc Builtins __builtin_execl(), __builtin_execle()
libc execv(), popen(), system()
Win32 CreateProcessA(), CreateProcessW(), _wsystem()
