检测方法
Manual Static Analysis
This might require an understanding of intended program behavior or design to determine whether the value is incorrect.
示例代码
例
This Perl code intends to record whether a user authenticated successfully or not, and to exit if the user fails to authenticate. However, when it calls ReportAuth(), the third argument is specified as 0 instead of 1, so it does not exit.
bad Perl
sub ReportAuth {
my ($username, $result, $fatal) = @_;
PrintLog("auth: username=%s, result=%d", $username, $result);
if (($result ne "success") && $fatal) {
PrintLog("auth: username=%s, result=%d", $username, $result);
if (($result ne "success") && $fatal) {
die "Failed!n";
}
}
sub PrivilegedFunc
{
my $result = CheckAuth($username);
ReportAuth($username, $result, 0);
DoReallyImportantStuff();
ReportAuth($username, $result, 0);
DoReallyImportantStuff();
}
