Fortra FileCatalyst Workflow Receives Fix for a Critical SQL Injection (CVE-2024-5276), PoC Available

Fortra recently patched a critical vulnerability in FileCatalyst Workflow, identified as CVE-2024-5276 with a CVSS score of9.8. If exploited, this vulnerability could allow an attacker to tamper with the application database.

FileCatalyst Workflow is a widely used file transfer acceleration solution that offers a web portal to streamline large file exchanges, enhancing business productivity.

What is CVE-2024-5276?

CVE-2024-5276 is an SQL injection vulnerability in Fortra FileCatalyst Workflow that allows an attacker to modify application data. According to Fortra, likely impacts include creating administrative users and deleting or altering data in the application database.

Fortra additionally notes that successful unauthenticated exploitation requires a Workflow system with anonymous access enabled, though it can also be exploited by an authenticated user.

CVE-2024-5276 affects Fortra FileCatalyst Workflow versions 5.1.6 Build 135 and earlier.

Details of the PoC Exploit for CVE-2024-5276

Previously, we discussed a critical RCE vulnerability in FileCatalyst (CVE-2024-25153) that rapidly gained attention, with researchers quickly devising a Proof-of-Concept (PoC) exploit. Similarly, CVE-2024-5276 also has a PoC exploit available soon after its disclosure.

Theexploitleverages the vulnerability in the workflow web application to perform anonymous logins and executeSQL injection (SQLi)attacks, adding a new administrator user,“operator,”with a specified password. Remote attackers can use a user-supplied jobID in various URL endpoints to form the WHERE clause in an SQL query to perform SQLi.

How to fix CVE-2024-5276?

The vulnerability has been addressed in version5.1.6 build 139. For more information and to access updates, visit Fortra’sadvisory.

For users unable to apply the patches immediately,disablingthe vulnerable servlets in the “web.xml” file located in the Apache Tomcat installation directory can serve as a temporary workaround. These are:

• csv_servlet
• pdf_servlet
• xml_servlet
• json_servlet

A guide to disabling these servlets is availablehere.

New MOVEit Transfer & Gateway Vulnerabilities, CVE-2024-5805 and CVE-2024-5806: Exploitation Attempts Surge

Progress Software has addressed two significant vulnerabilities in their MOVEit managed file transfer (MFT) software: CVE-2024-5805 and CVE-2024-5806. These vulnerabilities pose severe security risks, particularly in MOVEit Transfer and MOVEit Gateway.

The MOVEit catastrophe caused by theCl0pransomware last year highlights the critical role MOVEit plays in many organizations and underscores that these vulnerabilities must not be underestimated.

Progress Software even privately instructed users to apply hotfixes before publicly disclosing the new vulnerabilities, emphasizing their seriousness.

What Is CVE-2024-5805 and How Was It Discovered?

CVE-2024-5805(CVSS: 9.1) is a critical improper authentication vulnerability found in MOVEit Gateway, which acts as a proxy to allow MOVEit Transfer to receive inbound connections behind a firewall.

Discovered by security researcher Max Hase, this flaw affects theSecure File Transfer Protocol (SFTP)module in MOVEit Gateway version 2024.0.0. Attackers can exploit this vulnerability to bypass authentication, compromising the security of the system.

What Does CVE-2024-5806 Entail?

CVE-2024-5806(CVSS: 9.1) is another authentication bypass vulnerability, also posing critical severity.

This vulnerability affects MOVEit Transfer versions from 2023.0.0 before 2023.0.11, from 2023.1.0 before 2023.1.6, and from 2024.0.0 before 2024.0.2.

The vulnerability lies in the SFTP module and can lead to authentication bypass in specific scenarios. Unlike CVE-2024-5805, CVE-2024-5806 also impacts MOVEitCloudenvironments.

Exploitation Attempts Targeting MOVEit’s CVE-2024-5806

Exploitation attempts for CVE-2024-5806 began shortly after the details were disclosed. Details and a Proof-of-Concept (PoC) exploit for the CVE-2024-5806 vulnerability are already available; moreover,Shadowserverreports related exploitation attempts on their honeypots.

The vulnerability can be weaponized to impersonate any user on the server, as explained by WatchTowr Labs researchers Aliz Hammond and Sina Kheirkhah. They also identified that the vulnerability arises from the interplay between MOVEit and the IPWorks SSH library.

Researchers noted that attackers must know an existing username, the target account must authenticate remotely, and the SFTP service must be publicly accessible to exploit CVE-2024-5806. This requirement, while minimal, helps limit the scope of automated attacks.

For a demonstration as to how CVE-2024-5806 works, see the PoC exploit onGitHub.

The Attack Surface

Researchers state observing around2,700MOVEit Transfer instances online, primarily in the U.S., Europe, and other regions. You can also view exposed MOVEit Transfer instances on Shadowserver:

How Can You Address These Vulnerabilities?

While CVE-2024-5805 does not affect MOVEit Cloud, as it does not use MOVEit Gateway, CVE-2024-5806 does impact MOVEit Cloud users. Progress Software has patched this issue for both cloud and on-premises installations, and urges users to upgrade to the latest versions:

For CVE-2024-5805, users must update to MOVEit Gateway version:

• 2024.0.1

For CVE-2024-5806, users should upgrade to MOVEit Transfer versions:

• 2023.0.11
• 2023.1.6
• 2024.0.2

The company highlighted that using the full installer is essential to ensure proper remediation and warned that the upgrade process would cause system outages.

The company also advised customers to block public inbound Remote Desktop Protocol (RDP) access to MOVEit Transfer servers and limit outbound access to known trusted endpoints to mitigate risks further.

All in all, to prevent exploitation of your MOVEit products:

• Apply the latest patches for MOVEit Gateway and MOVEit Transfer.
• Block public inbound RDP access to MOVEit Transfer servers.
• Limit outbound access to known trusted endpoints from MOVEit Transfer servers.
• Regularly monitor and update systems to address any new vulnerabilities promptly.
