CVE-2025-11607 identifies a path traversal vulnerability in the MoneyPrinterTurbo application developed by harry0703, specifically affecting versions 1.2.0 through 1.2.6. The vulnerability resides in the upload_music function within the app/controllers/v1/music.py file, which handles file uploads via an API endpoint. An attacker can manipulate the 'File' argument to traverse directories outside the intended upload folder, potentially accessing or overwriting arbitrary files on the server. This can lead to unauthorized disclosure of sensitive information or modification of critical files, undermining system integrity. The vulnerability is remotely exploitable without user interaction and requires only low privileges, increasing its accessibility to attackers. Although no active exploitation has been reported, proof-of-concept exploits are publicly available, increasing the risk of future attacks. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). This suggests that while the vulnerability is not trivial, it can be exploited with relative ease and may have moderate consequences. The absence of patches or official remediation guidance at the time of publication necessitates immediate attention from users of the affected software to implement compensating controls.

For European organizations, the path traversal vulnerability in MoneyPrinterTurbo could lead to unauthorized access to sensitive files, including configuration files, credentials, or proprietary data, thereby compromising confidentiality. Integrity could be affected if attackers overwrite or modify files, potentially leading to data corruption or the insertion of malicious code. Availability impact is likely low but could occur if critical system files are tampered with. Financial institutions, media companies, or any entities relying on MoneyPrinterTurbo for financial or transactional processing are particularly at risk due to the sensitive nature of their data. The remote exploitability without user interaction increases the threat level, especially in environments with exposed API endpoints. This vulnerability could facilitate lateral movement within networks or serve as a foothold for further attacks. Given the public availability of exploit code, the window for exploitation is significant, and European organizations must act swiftly to mitigate risks. Failure to address this vulnerability could result in regulatory penalties under GDPR if personal data is exposed.

1. Immediate implementation of strict input validation and sanitization on the 'File' parameter within the upload_music API endpoint to prevent directory traversal sequences such as '../'. 2. Employ web application firewalls (WAFs) with rules specifically designed to detect and block path traversal attempts targeting the affected endpoint. 3. Restrict file system permissions for the application process to the minimum necessary, ensuring it cannot access or modify files outside designated directories. 4. Monitor server logs and file access patterns for unusual activity indicative of traversal attempts or unauthorized file access. 5. If possible, isolate the MoneyPrinterTurbo application in a segmented network zone to limit potential lateral movement. 6. Engage with the vendor or community to obtain patches or updates as soon as they become available. 7. Conduct regular security assessments and penetration testing focusing on file upload functionalities. 8. Educate development teams on secure coding practices to prevent similar vulnerabilities in future releases.
