Executive Summary

This vulnerability exists in AstrBot version 4.16.0 and involves hardcoded default credentials in the web dashboard's authentication system. These credentials remain active even after deployment, allowing unauthorized users to gain access. Additionally, the authentication mechanism is vulnerable to timing attacks because it uses standard equality operators for password comparison, enabling attackers to brute-force passwords character by character.

An attacker exploiting this vulnerability can gain full administrative access to the bot's configuration, logs, and integrated LLM API keys, potentially leading to full system compromise or remote code execution if certain tools are enabled.

Impact Analysis

The impact of this vulnerability includes unauthorized administrative access to the AstrBot system. Attackers can access sensitive configuration data, logs, and API keys, which may lead to full system compromise.

If certain tools are enabled, the attacker could execute remote code, further escalating the severity of the breach.

Detection Guidance

This vulnerability can be detected by checking for the presence of hardcoded default credentials in the AstrBot dashboard component, specifically in the file astrbot/dashboard/routes/auth.py.

You can attempt to detect unauthorized access attempts by monitoring login attempts to the AstrBot dashboard for repeated failed logins or timing attack patterns.

Suggested commands include searching the source code for hardcoded credentials and testing authentication behavior:

• Use grep or similar tools to find hardcoded credentials in the source code: grep -r 'password' astrbot/dashboard/routes/auth.py
• Monitor authentication logs for repeated failed login attempts or unusual timing patterns.
• Attempt to login using known default credentials or brute-force tools to verify if authentication bypass is possible.

Useful 0 Not Useful 0

Mitigation Strategies

Immediate mitigation steps include removing any hardcoded default credentials from the AstrBot dashboard authentication system.

Implement constant-time password comparison functions to prevent timing attacks.

Use secure password hashing algorithms such as Argon2 or bcrypt for storing and verifying credentials.

Restrict remote access to the dashboard until the vulnerability is fully addressed.

Monitor system logs for suspicious activity and unauthorized access attempts.

Compliance Impact

The vulnerability involves hardcoded default credentials and authentication bypass in the AstrBot platform, allowing unauthorized access to administrative functions and sensitive data such as configuration, logs, and API keys.

Such unauthorized access risks violating common security requirements found in standards and regulations like GDPR and HIPAA, which mandate protection of personal data and secure access controls.

Specifically, the presence of hardcoded credentials and susceptibility to brute-force attacks could lead to data breaches or unauthorized data processing, potentially resulting in non-compliance with these regulations.

Therefore, this vulnerability negatively impacts compliance by undermining the confidentiality and integrity controls required by these standards.
