CVE-2025-49089 is a path traversal vulnerability identified in wangxutech MoneyPrinterTurbo version 1.2.6. The vulnerability arises from insufficient validation of user-supplied input in the /api/v1/download/ endpoint. Specifically, an attacker can craft a URI such as /api/v1/download//etc/passwd to traverse directories and access arbitrary files on the server's filesystem. This type of vulnerability allows unauthorized reading of sensitive files outside the intended directory scope, potentially exposing critical system files, configuration data, or application secrets. The vulnerability does not require authentication or user interaction, making it easier for remote attackers to exploit. Although no known exploits are currently reported in the wild, the lack of a patch and the straightforward nature of the attack vector pose a significant risk. The absence of a CVSS score limits precise severity quantification, but the technical details indicate a serious security flaw that could compromise confidentiality and integrity of data on affected systems.

For European organizations using wangxutech MoneyPrinterTurbo 1.2.6, this vulnerability could lead to unauthorized disclosure of sensitive information such as system configuration files, user credentials, or proprietary data stored on the server. This exposure can facilitate further attacks including privilege escalation, lateral movement, or data breaches. Given the potential access to critical files like /etc/passwd, attackers might gain insights into user accounts and system structure, increasing the risk of subsequent exploitation. The impact is particularly severe for organizations handling sensitive personal data under GDPR, as unauthorized data exposure could result in regulatory penalties and reputational damage. Additionally, sectors with high-value intellectual property or critical infrastructure components could face operational disruptions or espionage risks if attackers leverage this vulnerability.

To mitigate this vulnerability, organizations should immediately audit their use of wangxutech MoneyPrinterTurbo and identify any instances of version 1.2.6. If possible, upgrade to a patched version once available. In the absence of an official patch, implement strict input validation and sanitization on the /api/v1/download/ endpoint to prevent directory traversal sequences such as '../' or absolute paths. Employ web application firewalls (WAFs) configured to detect and block path traversal attempts. Restrict file system permissions for the application user to limit access to only necessary directories and files, minimizing the impact of any successful traversal. Conduct thorough security testing, including fuzzing and penetration testing, to identify and remediate similar vulnerabilities. Finally, monitor logs for suspicious access patterns targeting the download API and establish incident response procedures for potential exploitation attempts.
