CWE-536: Servlet Runtime Error Message Containing Sensitive Information
A servlet error message indicates that there exists an unhandled exception in the web application code and may provide useful information to an attacker.
How it's found
Servlet Runtime Error Message Containing Sensitive Information is a specific, narrowly defined instance of a broader pattern. Testers confirm it with targeted code review and a proof-of-concept input that exercises the exact code path this weakness describes.
Consequences
- Read Application Data: The error message may contain the location of the file in which the offending function is located. This may disclose the web root's absolute path as well as give the attacker the location of application files or configuration information. It may even disclose the portion of code that failed. In many cases, an attacker can use the data to launch further attacks against the system.
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.
