Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Reliance on Cookies without Validation and Integrity Checking
The product relies on the existence or values of cookies when performing security-critical operations, but it does not properly ensure that the setting is valid for the associated user.
How developers prevent this class of flaw
- Avoid using cookie data for a security-related decision.
- Perform thorough input validation (i.e.: server side validation) on the cookie data if you're going to use it for a security related decision.
- Add integrity checks to detect tampering.
