CWE-1295 Base Incompleto
Debug Messages Revealing Unnecessary Information
The product's debug messages or logs expose excessive internal system details, potentially revealing sensitive information that could aid an attacker.
Definição
What is CWE-1295?
The product's debug messages or logs expose excessive internal system details, potentially revealing sensitive information that could aid an attacker.
Debug messages are essential for developers to diagnose issues by showing the system's internal state, such as memory dumps, boot logs, or low-level hardware data exposed through interfaces like UART or scan chains. While more detailed logs make troubleshooting easier, they also risk exposing information that could help an attacker identify vulnerabilities or understand the system's architecture.
Relying solely on hiding information (security through obscurity) is not a safe strategy, but it can be a useful layer within a broader defense-in-depth approach. Unnecessary details in debug output lower this protective layer, making it easier for attackers to piece together an attack even when other security controls are in place.
Impacto no mundo real
Real-world CVEs caused by CWE-1295
-
Digital Rights Management (DRM) capability for mobile platform leaks pointer information, simplifying ASLR bypass
-
Processor generates debug message that contains sensitive information ("addresses of memory transactions").
-
modem debug messages include cryptographic keys
Como os atacantes a exploram
Trajeto do atacante passo a passo
- 1
This example here shows how an attacker can take advantage of unnecessary information in debug messages.
- 2
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.
- 3
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 ."
- 4
The result of the above examples is that the user is able to gather additional unauthorized information about the system from the debug messages.
- 5
The solution is to ensure that Debug messages do not reveal additional details.
Exemplo de código vulnerável
Vulnerable pseudo
A MITRE não publicou um exemplo de código para este CWE. O padrão abaixo é ilustrativo — consulte os Recursos para referências canónicas.
// Example pattern — see MITRE for the canonical references.
function handleRequest(input) {
// Untrusted input flows directly into the sensitive sink.
return executeUnsafe(input);
} Exemplo de código seguro
Secure pseudo
// Validate, sanitize, or use a safe API before reaching the sink.
function handleRequest(input) {
const safe = validateAndEscape(input);
return executeWithGuards(safe);
} What changed: the unsafe sink is replaced (or the input is validated/escaped) so the same payload no longer triggers the weakness.
