Incomplete List of Disallowed Inputs
CWE-184
The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.
We track 141 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 8.5. 2 have been exploited in real attacks.
How this weakness is prevented
- Implementation: Do not rely exclusively on detecting disallowed inputs. There are too many variants to encode a character, especially when different environments are used, so there is a high likelihood of missing some variants. Only use detection of disallowed inputs as a mechanism for detecting suspicious activity. Ensure that you are using other protection mechanisms that only identify good input - such as lists of allowed inputs - and ensure that you are properly encoding your outputs.
