CWE-489: Active Debug Code
The product is released with debugging code still enabled or active.
How it's found
Active Debug Code is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
Consequences
- Bypass Protection Mechanism, Read Application Data, Gain Privileges or Assume Identity, Varies by Context: Active debug code can create unintended entry points or expose sensitive information. The severity of the exposed debug code will depend on the particular instance. At the least, it will give an attacker sensitive information about the settings and mechanics of web applications on the server. At worst, as is often the case, the debug code will allow an attacker complete control over the web application and server, as well as confidential information that either of these access.
Mitigations
- Build and Compilation/Distribution: Remove debug code before deploying the application.
How TurboPentest tests for this (white-box)
This weakness (Active Debug Code) is caught by white-box static analysis when you connect a GitHub repo: IntegSec's Opengrep SAST rule pack carries 11 rules for it, flagging the issue directly in your source code as part of the pentest.
