Technical Details

CVE-2023-34362 vulnerability is present in versions of MOVEit Transfer before 2021.0.6 (13.0.6), 2021.1.4 (13.1.4), 2022.0.4 (14.0.4), 2022.1.5 (14.1.5), and 2023.0.1 (15.0.1).

The vulnerability can be exploited by an unauthenticated attacker by sending a specially crafted request to a vulnerable MOVEit Transfer instance. Successful exploitation of the vulnerability would give an attacker access to the underlying MOVEit Transfer instance. An attacker can use this access to exfiltrate data, install web shells, and carry out other malicious activities.

The vulnerability is caused by a lack of input validation in the MOVEit Transfer web application. The vulnerability allows an attacker to inject malicious SQL code into a database query, which can then be executed by the database. This can lead to unauthorized access to the database and the ability to perform actions such as data exfiltration.

The vulnerability can be mitigated by upgrading to a patched version of MOVEit Transfer. Progress released patches for the vulnerability on May 31, 2023. If upgrading is not possible, administrators can also mitigate the vulnerability by implementing strict input validation and sanitization to prevent SQL injection attacks. Additionally, administrators can restrict access to the MOVEit Transfer web application to trusted networks and users.

Conclusion and Future Prevention

CVE-2023-34362 and CVE-2023-35708 vulnerabilities in MOVEit Transfer have highlighted the importance of taking proactive steps to secure file transfer environments.

Existing detections for SQL injection and privilege escalation vulnerabilities should be updated and reviewed regularly to ensure that they are effective against the latest threats. Organizations should also consider implementing additional security measures such as intrusion detection and prevention systems (IDS/IPS), firewalls, and network segmentation to further enhance their security posture.

With the rise of remote workforces, it is essential to ensure that all employees are aware of the risks associated with file transfers and are trained to follow best practices when transferring files. This includes using secure file transfer protocols, avoiding the use of personal email accounts, and verifying the authenticity of file transfer requests.

Having dedicated experts on staff or utilizing third-party security professionals can help organizations stay ahead of emerging threats and ensure that their security policies and procedures are up to date.

Compression should also be used with caution as it can obscure the contents of files and make it more difficult to detect malicious activity. Organizations should consider implementing additional security measures such as file integrity monitoring and anti-malware solutions to detect and prevent malicious activity.

The recent attacks by the Cl0p ransomware gang have demonstrated the importance of regularly backing up data and having a comprehensive incident response plan in place. Organizations should also consider implementing multi-factor authentication and access controls to prevent unauthorized access to sensitive data.

By following best practices and implementing a layered approach to security, organizations can reduce their risk of falling victim to file transfer vulnerabilities and better protect their sensitive data.
