CVE-2025-69618: Tarot, Astro & Healing RCE Vulnerability

CVE-2025-69618 Overview

An arbitrary file overwrite vulnerability exists in the file import process of Tarot, Astro & Healing v11.4.0. This vulnerability allows attackers to overwrite critical internal files, potentially leading to arbitrary code execution or exposure of sensitive information. The flaw resides in how the application handles file imports without proper validation of file paths, enabling malicious actors to write to arbitrary locations on the filesystem.

Critical Impact

Successful exploitation could allow attackers to overwrite critical system or application files, potentially leading to arbitrary code execution, data corruption, or disclosure of sensitive information.

Technical Details for CVE-2025-69618

Vulnerability Analysis

This vulnerability represents a classic arbitrary file overwrite condition within the file import functionality of the Tarot, Astro & Healing application. The application fails to properly sanitize or validate file paths during the import process, allowing attackers to specify arbitrary destination paths for imported files. When a user imports a specially crafted file or uses a malicious import configuration, the application writes data to locations outside the intended directory structure.

The security implications are significant as this type of vulnerability can be leveraged in multiple attack scenarios. Attackers could overwrite configuration files to modify application behavior, replace legitimate application binaries with malicious payloads, or target system files if the application runs with elevated privileges. In scenarios where the application stores sensitive data, attackers could also potentially expose this information by redirecting file operations.

Root Cause

The root cause of this vulnerability stems from insufficient input validation in the file import process. The application does not adequately sanitize user-controlled file path input, failing to prevent path traversal sequences or absolute path specifications. This allows malicious input to escape the intended import directory and target arbitrary filesystem locations accessible by the application process.

Attack Vector

The attack vector involves manipulation of the file import functionality. An attacker could exploit this vulnerability by:

1. Crafting a malicious import file or manipulating import parameters to include path traversal sequences (e.g., ../../../) or absolute file paths
2. Triggering the import process either locally or potentially remotely if the import functionality is exposed through a network interface
3. The application processes the malicious path without proper validation, writing data to the attacker-specified location
4. Depending on the target file and application privileges, this could result in code execution, denial of service, or information disclosure

The vulnerability requires an attacker to have access to the file import functionality. The specific attack complexity and required privileges depend on the application's deployment configuration and access controls.

Detection Methods for CVE-2025-69618

Indicators of Compromise

• Unexpected file modifications in system directories or application installation paths
• Presence of suspicious files outside the normal import directory structure
• Log entries showing unusual file paths in import operations
• Modification timestamps on critical configuration files that don't correspond to legitimate administrative activities

Detection Strategies

• Monitor file system activity for write operations targeting sensitive directories during application import processes
• Implement file integrity monitoring (FIM) on critical application and system files to detect unauthorized modifications
• Review application logs for import operations containing path traversal sequences such as ../ or absolute paths
• Deploy endpoint detection solutions to identify suspicious file write patterns indicative of path traversal exploitation

Monitoring Recommendations

• Enable detailed logging for all file import operations within the application
• Configure alerts for file write operations outside designated import directories
• Implement real-time file integrity monitoring on critical application configuration files
• Monitor for unusual process behavior following file import operations that could indicate post-exploitation activity

How to Mitigate CVE-2025-69618

Immediate Actions Required

• Disable or restrict access to the file import functionality until a patch is available
• Implement network-level controls to limit access to the application to trusted users only
• Review recent import activity logs for any suspicious path patterns or unexpected file modifications
• Apply principle of least privilege to the application process to minimize potential impact

Patch Information

No official patch information is currently available from the vendor. Security teams should monitor the GitHub Issue #9 for updates and the vendor resources at Coto World for official security advisories. Until a patch is released, organizations should implement the recommended workarounds to reduce exposure.

Workarounds

• Restrict access to the file import functionality to trusted administrators only
• Implement strict input validation at the network or application proxy layer to reject requests containing path traversal sequences
• Run the application with minimal filesystem permissions to limit the scope of potential file overwrites
• Deploy application-level firewalls or security controls to filter malicious import requests

# Example: Restrict application write permissions (Linux)
# Limit the application user's write access to only necessary directories
chmod 755 /path/to/application/import_directory
chown appuser:appgroup /path/to/application/import_directory
# Consider using mandatory access controls (SELinux/AppArmor) for additional protection
