Indusface Threat Coverage: MOVEit Transfer SQL Injection Vulnerabilities
Progress has recently raised concerns about multiple vulnerabilities in their MOVEit Transfer secure managed file transfer solution. These vulnerabilities have been publicly disclosed within the past several weeks, and the most recent one was reported on June 15, 2023.
Notably, the latest vulnerability is claimed to be a zero-day SQL injection vulnerability. If exploited by an attacker, these vulnerabilities can lead to unauthorized access to the MOVEit Transfer database.
Multiple Vulnerabilities on MOVEit Transfer
As of now, three vulnerabilities have been disclosed and brought to attention. These vulnerabilities are as follows:
- CVE-2023-34362 (May 31, 2023)
- CVE-2023-35036 (June 9, 2023)
- CVE-2023-35708 (June 15, 2023)
In late May 2023, Progress disclosed a critical vulnerability (CVE-2023-34362) found in the MOVEit Transfer web application. This vulnerability, classified as an SQL Injection flaw, poses a significant risk as it could enable unauthorized access to the database of MOVEit Transfer.
Attackers associated with the Clop ransomware operation have been exploiting the CVE-2023-34362 vulnerability as a zero-day before it was patched. The public proof-of-concept code for this exploit indicates that other malicious actors are highly likely to target vulnerable systems that have not yet been patched.
