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.)

Définition
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.
Impact réel
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.
Comment les attaquants l'exploitent
Parcours de l'attaquant étape par étape
- 1
Identifier un chemin de code qui traite des entrées non fiables sans validation.
- 2
Élaborer une charge utile qui exploite le comportement non sécurisé — injection, traversal, débordement ou abus de logique.
- 3
Délivrer la charge utile via une requête normale et observer la réaction de l'application.
- 4
Itérer jusqu'à ce que la réponse divulgue des données, exécute le code de l'attaquant ou élève les privilèges.
Exemple de code vulnérable
Vulnerable JSP
The following comment, embedded in a JSP, will be displayed in the resulting HTML output.
<!-- FIXME: calling this with more than 30 args kills the JDBC server --> Exemple de code sécurisé
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.
Liste de contrôle de prévention
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.

Frequently asked questions
Qu'est-ce que 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.
Quelle est la gravité de CWE-615 ?
MITRE n'a pas publié de note de probabilité d'exploitation pour cette faiblesse. Traitez-la comme un impact moyen jusqu'à ce que votre modèle de menace prouve le contraire.
Quels langages ou plateformes sont affectés par CWE-615 ?
MITRE n'a pas spécifié les plateformes affectées pour ce CWE — il peut s'appliquer à la plupart des stacks applicatives.
Comment puis-je prévenir CWE-615 ?
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.
Comment Plexicus détecte et corrige CWE-615 ?
Le moteur SAST de Plexicus reconnaît la signature de flux de données de CWE-615 à chaque commit. Lorsqu'une correspondance est trouvée, notre agent Codex Remedium ouvre une PR de correction avec le code corrigé, les tests et un résumé d'une ligne pour le relecteur.
Où puis-je en savoir plus sur CWE-615 ?
MITRE publie la définition canonique à https://cwe.mitre.org/data/definitions/615.html. Vous pouvez également consulter la documentation OWASP et NIST pour des conseils adjacents.
