CWE-707: Improper Neutralization

How it's found

Improper Neutralization is a broad weakness category rather than one exact bug. Testers narrow it down through manual code review and architecture review to identify which of its more specific child weaknesses actually appears in a given target, then confirm each one individually.

If a message is malformed, it may cause the message to be incorrectly interpreted. Neutralization is an abstract term for any technique that ensures that input (and output) conforms with expectations and is "safe." This can be done by: This weakness typically applies in cases where the product prepares a control message that another process must act on, such as a command or query, and malicious input that was intended as data, can enter the control plane instead. However, this weakness also applies to more general cases where there are not always control implications.checking that the input/output is already "safe" (e.g. validation) transformation of the input/output to be "safe" using techniques such as filtering, encoding/decoding, escaping/unescaping, quoting/unquoting, or canonicalization preventing the input/output from being directly provided by an attacker (e.g. "indirect selection" that maps externally-provided values to internally-controlled values) preventing the input/output from being processed at all

Where this fits in a TurboPentest engagement

This weakness is not covered by the automated black-box pentest. IntegSec pentesters cover it in a manual engagement.
