Definición

What is CWE-615?

This vulnerability occurs when developers leave sensitive details within source code comments. These can include internal file paths, hidden URLs, inactive code snippets, credentials, or other information meant for internal use only.
Comments containing sensitive data act as a roadmap for attackers. By scanning these comments, an attacker can uncover the application's internal structure, discover hidden files or administrative endpoints, and piece together how the software works, significantly reducing the effort needed to plan an attack. To prevent this, treat comments as part of your public-facing code. Establish a review process to scrub comments before deployment, and use environment variables or secure configuration files for any operational details like paths or links. Remember, if it shouldn't be seen by users, it shouldn't be in the comments.
Impacto en el mundo real

Real-world CVEs caused by CWE-615

  • Version numbers and internal hostnames leaked in HTML comments.

  • CMS places full pathname of server in HTML comment.

  • blog software leaks real username in HTML comment.

Cómo lo explotan los atacantes

Ruta del atacante paso a paso

  1. 1

    Identifica una ruta de código que maneje entrada no confiable sin validación.

  2. 2

    Crea un payload que ejercite el comportamiento inseguro — inyección, traversal, overflow o abuso de lógica.

  3. 3

    Envía el payload a través de una solicitud normal y observa la reacción de la aplicación.

  4. 4

    Itera hasta que la respuesta filtre datos, ejecute código del atacante o escale privilegios.

Ejemplo de código vulnerable

Vulnerable JSP

The following comment, embedded in a JSP, will be displayed in the resulting HTML output.

Vulnerable JSP
<!-- FIXME: calling this with more than 30 args kills the JDBC server -->
Ejemplo de código seguro

Secure pseudo

Seguro 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.
Lista de prevención

How to prevent CWE-615

  • Distribution Remove comments which have sensitive information about the design/implementation of the application. Some of the comments may be exposed to the user and affect the security posture of the application.
Señales de detección

How to detect CWE-615

Automated Static Analysis High

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.)
