Determining the type of database may assist attackers in exploiting +SQL Injection attacks against the system. While debug messages are helpful during development and debugging, they should not be +presented to users when an error occurs. + +## Remediation + +Applications should handle database error conditions internally and map known failure types to error codes that can be displayed +to a user. These error codes should be customized to the application and returned along with the relevant HTTP error code. + +When an error occurs, the application identifies the error type or class, and displays a numerical value to the +user. Requests should also be tracked so when a user is presented with an error code, it has a corresponding request ID. +Support teams can then correlate the HTTP error, the customized error code, and the request ID in the log files to +determine the root cause of the error without leaking details to the end user. + +Example of returning customized errors: + +```plaintext +HTTP/1.1 500 Internal Server Error +... +Error [0004] Occurred, please contact support or re-try your request again shortly. +Request ID [a4bc91def12] +... +``` + +## Details + +| ID | Aggregated | CWE | Type | Risk | +|:---|:--------|:--------|:--------|:--------| +| 209.2 | false | 209 | Passive | Low | + +## Links + +- [CWE](https://cwe.mitre.org/data/definitions/209.html) |
