Glexia's Take · Automated analysis
CWE-1295: Debug Messages Revealing Unnecessary Information
Debug Messages Revealing Unnecessary Information represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact

Developer Pattern
CWE-1295 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.
Automation confidence
high confidence from CWE-1295, 4.20.

Official CWE Definition
CWE-1295: Debug Messages Revealing Unnecessary Information
The product fails to adequately prevent the revealing of unnecessary and potentially sensitive system information within debugging messages.
Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- This example here shows how an attacker can take advantage of unnecessary information in debug messages. Example 1: Suppose in response to a Test Access Port (TAP) chaining request the debug message also reveals the current TAP hierarchy (the full topology) in addition to the success/failure message.,Example 2: In response to a password-filling request, the debug message, instead of a simple Granted/Denied response, prints an elaborate message, "The user-entered password does not match the actual password stored in <directory name>.",The result of the above examples is that the user is able to gather additional unauthorized information about the system from the debug messages.,The solution is to ensure that Debug messages do not reveal additional details.
Remediation
- Implementation: Ensure that a debug message does not reveal any unnecessary information during the debug process for the intended response.
Detection
- Automated Static Analysis: Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
