Summary
TSPortal: Any user can forge self-deletion requests for any account
Details
Summary
Conversion of empty strings to null allows disguising DPA reports as genuine self-deletion reports.
Details
Creating a DPA report about another user and leaving the evidence field empty causes that report to look like the reported user self-requested deletion of their data. Ingenuine report is not distinguishable from a genuine one.
This can be prevented by disabling convertEmptyStringsToNull in the middleware, or by validating evidence in Http/Controllers/DPAController::store() to not be empty.
PoC
New DPA report -> Select "...someone who I suspect is under the age of 13" for the "The above username is..." field -> Add nothing to the "Evidence" field -> Submit
Impact
Potential unauthorized deletion of any arbitrary user's data both in the current system (TSPortal) and subsequent systems if actioned.

Mitigation MIT-5
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
