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.)

Definição
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 no 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.
Como os atacantes a exploram
Trajeto do atacante passo a passo
- 1
Identificar um caminho de código que trata input não confiável sem validação.
- 2
Criar um payload que explora o comportamento inseguro — injeção, traversal, overflow ou abuso de lógica.
- 3
Entregar o payload através de um pedido normal e observar a reação da aplicação.
- 4
Iterar até que a resposta exponha dados, execute código do atacante ou escale privilégios.
Exemplo de código vulnerável
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 --> 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.
Lista de verificação de prevenção
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
O que é o 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.
Qual a gravidade do CWE-615?
A MITRE não publicou uma classificação de probabilidade de exploração para esta fraqueza. Trate-a como impacto médio até o seu modelo de ameaças provar o contrário.
Que linguagens ou plataformas são afetadas pelo CWE-615?
A MITRE não especificou as plataformas afetadas por este CWE — pode aplicar-se à maioria das stacks de aplicações.
Como posso prevenir o 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.
Como é que o Plexicus deteta e corrige o CWE-615?
O motor SAST do Plexicus correlaciona a assinatura de fluxo de dados do CWE-615 em cada commit. Quando é encontrada uma correspondência, o nosso agente Codex Remedium abre um PR de correção com o código corrigido, testes e um resumo de uma linha para o revisor.
Onde posso saber mais sobre o CWE-615?
A MITRE publica a definição canónica em https://cwe.mitre.org/data/definitions/615.html. Pode também consultar a documentação da OWASP e do NIST para orientações adjacentes.
