CVE-2025-48957 in AstrBot
Summary
by MITRE • 06/02/2025
AstrBot is a large language model chatbot and development framework. A path traversal vulnerability present in versions 3.4.4 through 3.5.12 may lead to information disclosure, such as API keys for LLM providers, account passwords, and other sensitive data. The vulnerability has been addressed in Pull Request #1676 and is included in version 3.5.13. As a workaround, users can edit the `cmd_config.json` file to disable the dashboard feature as a temporary workaround. However, it is strongly recommended to upgrade to version v3.5.13 or later to fully resolve this issue.

The vulnerability identified as CVE-2025-48957 affects AstrBot, a large language model chatbot and development framework that has gained significant traction in enterprise and research environments for building conversational AI applications. This path traversal vulnerability represents a critical security flaw that allows attackers to access sensitive files and data that should remain protected within the application's file system. The affected versions span from 3.4.4 through 3.5.12, indicating a substantial release range where organizations using AstrBot may be exposed to potential data breaches. The vulnerability's presence in such a widely used framework creates widespread risk across various deployment scenarios including cloud environments, on-premises installations, and containerized applications where AstrBot serves as a core component for AI-driven chatbot services.
The technical flaw stems from inadequate input validation and improper handling of file path parameters within AstrBot's dashboard functionality. When users interact with the dashboard feature, the application fails to properly sanitize user-supplied input that could contain directory traversal sequences such as ../ or ..\ characters. This allows malicious actors to navigate beyond the intended directory structure and access arbitrary files on the server where AstrBot is deployed. The vulnerability maps directly to CWE-22, which specifically addresses Improper Limitation of a Pathname to a Restricted Directory, commonly known as path traversal or directory traversal attacks. The flaw manifests when the application processes requests that should only operate within designated directories but instead permits access to the entire file system hierarchy, potentially exposing configuration files, credential stores, and other sensitive resources.
The operational impact of this vulnerability extends far beyond simple data exposure, as the sensitive information that can be accessed includes API keys for various large language model providers, account passwords, and potentially other confidential data stored within the application's configuration files. This creates a significant risk for organizations that rely on AstrBot for their AI infrastructure, as compromised API keys could lead to unauthorized usage of cloud services, financial losses through API abuse, and potential data exfiltration. The exposure of account passwords and other credentials could enable attackers to escalate privileges within the application or even gain access to underlying systems that support the chatbot infrastructure. Organizations using AstrBot in production environments face the risk of complete system compromise if attackers exploit this vulnerability to gain access to administrative credentials or system-level configuration data.
Security professionals should note that this vulnerability aligns with several tactics described in the MITRE ATT&CK framework, particularly those related to credential access and privilege escalation. The attack pattern follows T1566 for credential access through exploitation of weak input validation, and T1078 for legitimate credentials usage once access is gained. The recommended mitigation strategy includes immediate upgrading to version 3.5.13 or later, which incorporates the fix from Pull Request #1676 that properly implements input sanitization and path validation. While the temporary workaround of disabling the dashboard feature through modification of cmd_config.json provides a partial solution, it does not address the root cause and leaves the application vulnerable to other potential attack vectors. Organizations should conduct thorough security assessments of their AstrBot deployments, review access controls, and implement additional monitoring for unusual file access patterns that might indicate exploitation attempts. The vulnerability serves as a reminder of the critical importance of input validation in web applications and the potential consequences of inadequate security controls in AI development frameworks that handle sensitive data and credentials.
