Progress LoadMaster Command Injection

Published Updated By the CyberSecBulletin desk

CVE-2026-8037 is a critical-severity improper neutralization of special elements used in a command vulnerability in LoadMaster from Progress Software, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions V7.2.63.2, V7.2.54.18 as the first without the flaw, so updating LoadMaster to one of those releases or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on August 7, 2026, which means attacks have been observed in the wild.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Update LoadMaster to V7.2.63.2 or V7.2.54.18, whichever matches your release line, or a later version.
  2. Update ECS Connections Manager to V7.2.63.2 or a later version.
  3. Update Object Scale Connection Manager to V7.2.63.2 or a later version.
  4. CISA's required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
  5. Read the advisory on community.progress.com for workarounds and exact fixed builds.
  6. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

OS Command Injection Remote Code Execution Vulnerability in API in Progress ADC Products allows an un-authenticated attacker to execute arbitrary commands on the LoadMaster appliance by exploiting unsanitized input in multiple command endpoints

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Neutralization of Special Elements used in a Command

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
