Critical Vulnerability in Progress Software's LoadMaster - D1defend D1defend

What You Need to Know and How to Protect Your Network

In the ever-evolving cybersecurity landscape, new vulnerabilities emerge constantly, posing significant risks to organizations. The latest critical threat comes from Progress Software’s LoadMaster products, widely used as load-balancing solutions. A recently discovered vulnerability could allow remote, unauthenticated attackers to access your network and sensitive company data.

This vulnerability, identified as CVE-2024-7591 with a severity rating of 10.0 on the CVSS scale (the highest possible score), impacts multiple Progress devices, including the LoadMaster and LoadMaster Multi-Tenant (MT) Hypervisor. For businesses relying on these solutions, immediate action is necessary to mitigate potential risks and prevent unauthorized access to critical systems.

This blog will break down the details of this vulnerability, discuss who is affected, and outline the steps you need to take to protect your organization.

The Nature of the Vulnerability

The vulnerability in question arises from improper input validation within the affected Progress Software products. This flaw allows attackers to gain access to the LoadMaster’s management interface without authentication. Once access is granted, attackers can execute arbitrary system commands on the victim’s machine, compromising the security of the entire network.

This type of vulnerability is particularly dangerous as it provides attackers with a direct entry point into the network, bypassing traditional security controls. By gaining control of the LoadMaster’s management interface, an attacker could potentially intercept, manipulate, or even destroy sensitive data, significantly disrupting business operations.

Affected Products and Versions

This vulnerability affects a wide range of Progress Software products, particularly those used for load balancing. The specific devices and versions impacted are as follows:

• LoadMaster versions 7.2.60.0 and all previous versions
• MT Hypervisor versions 7.1.35.11 and all previous versions
• Long-Term Support (LTS) and Long-Term Support with Feature (LTSF) branches are also vulnerable.

If your organization is using any of these versions, you are at risk. Immediate action is required to patch and secure your systems.

Progress Software’s Response: A Patch Is Available

Progress Software has responded swiftly by releasing an add-on patch that addresses this vulnerability for most affected versions of LoadMaster and MT Hypervisor. This patch corrects the improper input validation flaw and strengthens the management interface against unauthorized access.

However, it’s important to note that this patch is not applicable to free versions of LoadMaster. If your organization is using the free version, the vulnerability remains unaddressed, and additional security measures should be implemented to protect your network.

Immediate Actions to Take

Given the severity of this vulnerability, there are several key steps you need to take to protect your organization from exploitation:

1. Apply the Patch Immediately: If you are using any of the affected versions of LoadMaster or MT Hypervisor, the first step is to apply the patch provided by Progress Software. The patch is available on their support portal, and you can follow the instructions provided in the forum post regarding LoadMaster Security Vulnerability CVE-2024-7591.
2. Harden Your Security Settings: In addition to applying the patch, Progress Software has outlined basic security hardening techniques that should be implemented to further protect your network. These measures include disabling unnecessary services, configuring firewalls to restrict access to the management interface, and enabling logging and monitoring to detect suspicious activity. For detailed steps on security hardening, refer to Progress’ post on LoadMaster Security Measures.
3. Monitor Your Network for Signs of Exploitation: Once the patch has been applied and security settings hardened, it’s crucial to monitor your network for any signs of exploitation. Use Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) to keep a close watch on network traffic and identify any abnormal or malicious activity. Regularly reviewing logs and running vulnerability scans can help detect potential attacks before they cause significant damage.

Why This Vulnerability Should Be Taken Seriously

Cybercriminals are constantly scanning the internet for unpatched systems they can exploit, and vulnerabilities like CVE-2024-7591 present a prime opportunity for attackers to gain access to corporate networks. Once inside, attackers can cause significant damage, from data breaches and financial losses to operational disruption and reputational harm.

In this case, the ability for an attacker to bypass authentication and execute arbitrary commands means that even organizations with strong perimeter defenses are at risk. If left unpatched, this vulnerability could be used to steal sensitive data, disrupt business operations, or launch further attacks against your network.

Quick Points to Remember

• Vulnerability ID: CVE-2024-7591 (CVSS score: 10.0)
• Severity: Critical
• Affected Versions: LoadMaster versions 7.2.60.0 and all previous versions; MT Hypervisor versions 7.1.35.11 and all previous versions; Long-Term Support (LTS) and Long-Term Support with Feature (LTSF) branches are all impacted.
• Immediate Action: Apply the add-on patch available from Progress Software’s support portal and follow the recommended security hardening steps.
