CWE-615 (通过注释导致的信息暴露) — Vulnerability Class 1

1 vulnerabilities classified as CWE-615 (通过注释导致的信息暴露). AI Chinese analysis included.

CWE-615 represents a critical information disclosure weakness where developers inadvertently embed sensitive data within source code comments. This vulnerability typically arises when programmers leave behind internal file paths, obsolete URLs, deprecated API endpoints, or fragments of legacy code that were not intended for public visibility. Attackers exploit this oversight by inspecting the client-side source code or network traffic to map the application’s internal structure and identify hidden resources. By analyzing these exposed details, adversaries can reverse-engineer logic, discover unpatched vulnerabilities, or locate sensitive administrative interfaces. To mitigate this risk, developers must rigorously sanitize code before deployment, ensuring all comments are reviewed for confidential information. Implementing automated static analysis tools that flag potential secrets in comments and enforcing strict code review policies are essential practices to prevent accidental exposure and maintain application security integrity.

MITRE CWE Description
While adding general comments is very useful, some programmers tend to leave important data, such as: filenames related to the web application, old links or links which were not meant to be browsed by users, old code fragments, etc. An attacker who finds these comments can map the application's structure and files, expose hidden parts of the site, and study the fragments of code to reverse engineer the application, which may help develop further attacks against the site.
Common Consequences (1)
ConfidentialityRead Application Data
Mitigations (1)
DistributionRemove 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.
