Progress Software fixed a maximum severity flaw in LoadMaster
September 09, 2024
Progress Software released an emergency to address a maximum severity vulnerability in its LoadMaster products.
Progress Software released an emergency fix for a critical vulnerability, tracked as CVE-2024-7591, that affects its LoadMaster and LoadMaster Multi-Tenant (MT) Hypervisor products.
The vulnerability is an improper input validation issue, that could allow an unauthenticated, remote attacker to access LoadMaster’s management interface using a specially crafted HTTP request.
“It is possible for unauthenticated, remote attackers who have access to the management interface of LoadMaster to issue a carefully crafted http request that will allow arbitrary system commands to be executed.” reads the advisory. “This vulnerability has been closed by sanitizing request user input to mitigate arbitrary system commands execution.”
Progress LoadMaster is a high-performance application delivery controller (ADC) and load balancer. It is designed to enhance the availability, scalability, performance, and security of business-critical applications and websites.
The vulnerability could enable an attacker to execute arbitrary commands on affected systems.
Below is the list of affected product versions:
Multi-Tenant LoadMaster (LoadMaster MT) is affected in case the following condition is met:
- The individual instantiated LoadMaster VNFs are vulnerable and must be patched using the add-on listed above as soon as possible.
- Note that the MT hypervisor or Manager node is also vulnerable and must be patched using the add-on listed above as soon as possible.
As reported by a user in the advisory comments, the addon package released by Progress doesn’t allow installation on the free version.
The good news is that Progress is not aware of attacks in the wild exploiting this vulnerability.
“We have not received any reports that this vulnerability has been exploited and we are not aware of any direct impact to customers” states the advisory. “Nevertheless, we are encouraging all customers to upgrade their LoadMaster implementations as soon as possible to harden their environment. “
