CRLF Injection

  • Risk:

  • Medium

  • Type:

Summary

Cookie can be set via CRLF injection. It may also be possible to set arbitrary HTTP response headers. In addition, by carefully crafting the injected response using cross-site script, cache poisoning vulnerability may also exist.

Solution

Type check the submitted parameter carefully. Do not allow CRLF to be injected by filtering CRLF.
