Exploitability

CWE

KEV
KEV Icon
CWE ID Description
CWE-257 The storage of passwords in a recoverable format makes them subject to password reuse attacks by malicious users. In fact, it should be noted that recoverable encrypted passwords provide no significant benefit over plaintext passwords since they are subject not only to reuse by malicious attackers but also by malicious insiders. If a system administrator can recover a password directly, or use a brute force search on the available information, the administrator can use the password on other accounts.

Executive Summary

This vulnerability involves usernames and passwords, including default credentials, being stored in a configuration file using weak encryption. A malicious user who knows the default credentials could potentially access and obtain other credentials on the system.

Detection Guidance

Check configuration files for stored credentials using weak encryption. Inspect files like config.ini or similar for plaintext or reversibly encrypted passwords. Use tools like grep to search for password patterns in files. Example commands: grep -r 'password' /path/to/config/files or strings /path/to/config/file | grep -i 'pass'.

Impact Analysis

An attacker could exploit this to gain unauthorized access to sensitive systems or data by retrieving stored credentials. This may lead to further compromise of the system, data breaches, or unauthorized control of connected devices.

Compliance Impact

The vulnerability involves storing usernames and passwords, including default credentials, in configuration files using weak encryption. This could allow unauthorized access to sensitive credentials, potentially violating data protection requirements under standards like GDPR and HIPAA, which mandate secure storage and protection of personal and health information.

Mitigation Strategies

Update device firmware to the latest version from the vendor. Change all default credentials to strong, unique passwords. Disable remote access if not required. Monitor network traffic for unauthorized access attempts. Restrict file access permissions to configuration files.
