Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-46658 is a vulnerability discovered in the ExonautWeb component of 4C Strategies Exonaut version 21.6, where verbose error messages are exposed. This issue falls under CWE-209 (Generation of Error Message Containing Sensitive Information) and has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its potential for high impacts across confidentiality, integrity, and availability.
The vulnerability can be exploited by unauthenticated attackers over the network with low attack complexity and no user interaction required. Successful exploitation allows attackers to obtain sensitive information from the verbose error messages, potentially enabling further compromise that achieves high-level impacts on confidentiality, integrity, and availability as scored by CVSS.

Secure coding standards explicitly forbid exposing sensitive data in errors.
Security testing can detect error messages that leak sensitive information.
Logging policy can require suppression of sensitive data in error messages.
Secure SDLC mandates error-handling rules that avoid leaking sensitive information.
Application security requirements can specify safe error messaging.
Secure architecture principles include proper exception handling.
