This is due to it successfully restrictions what's going to appear in output. Enter validation will never usually protect against OS command injection, especially if you will be necessary to assist absolutely free-type text fields which could include arbitrary people. For instance, when invoking a mail software, you may need to permit the topic subject to include otherwise-dangerous inputs like ";" and ">" people, which might should be escaped or usually managed. In such cases, stripping the character might lower the risk of OS command injection, but it might generate incorrect conduct because the topic discipline would not be recorded as being the consumer intended. This could possibly seem to be a small inconvenience, but it may be more vital when This system depends on effectively-structured subject matter lines in an effort to move messages to other parts. Even when you come up with a mistake with your validation (for instance forgetting just one away from one hundred enter fields), proper encoding remains very likely to shield you from injection-primarily based assaults. Assuming that It's not necessarily carried out in isolation, input validation remains a helpful system, as it may noticeably lessen your assault area, assist you to detect some assaults, and supply other protection Advantages that proper encoding will not tackle.
