CVE-2023-34362 vulnerability in MOVEit Transfer is a critical vulnerability that can be easily exploited by threat actors. Organizations must take immediate action to update their MOVEit Transfer instances and apply the necessary security patches to mitigate the risk of exploitation.
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.
