Remediation
The vendor's own words where we have them.
Upgrade LoadMaster to a fixed release. Apply vendor patches per advisory and restrict external exposure of the affected component until patched.
CISA 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.

First 24 hours
Ordered from the record's own fields — exposure first, because you cannot patch what you have not found.
- Identify exposed assets running affected vendor/product/version combinations.
- Treat as emergency remediation because CISA KEV status is present.
- Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class.

CISA added Progress LoadMaster CVE-2026-8037 to KEV on Aug. 7. It is an unauthenticated command-injection path with RCE impact. Progress lists LMOS 7.2.63.2 and 7.2.54.18 as fixed releases. Prioritize exposed appliances.
@InfosecDotWatch· Aug 14, 2026
CISA urged immediate patching of CVE-2026-8037, a critical command-injection flaw in Progress Kemp LoadMaster. The vulnerability allows unauthenticated remote code execution and is being actively exploited. Compromised LoadMaster devices could provide attackers with an entry
@unccno· Aug 12, 2026
792 exploit attempts. CISA deadline: yesterday. CVE-2026-8037 = CVSS 9.8 unauthenticated root RCE in Progress LoadMaster. No creds needed. Patch to GA 7.2.63.2 or LTSF 7.2.54.18 now. #LoadMaster #CISAKEV #CyberSecurity https://t.co/q0EoaLLHL6

Answered from this record1
What should defenders know first?
CVE-2026-8037 is OS Command Injection Remote Code Execution Vulnerability in Progress LoadMaster, ECS Connection Manager, Object Scale Connection Manager & MOVEit WAF, a critical vulnerability affecting LoadMaster, ECS Connections Manager, Object Scale Connection Manager, MOVEit WAF from Progress Software. The current evidence lists it in CISA KEV, and the exploit status is: Yes: CISA KEV signal present. Public exploit evidence is: 25 public PoC repositories reported; 2 marked weaponized in current dataset. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 9.8 describes technical severity, while EPSS 100% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
