2 techniques across 1 tactic: Execution

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

The Geo Location management interface must be enabled and accessible. The attacker must possess valid high-privilege credentials (administrator or equivalent) to the appliance. Network adjacency is required-the attack cannot be launched from outside the management network unless the management interface is exposed.

Impact

The CVSS 3.1 score is 8.4, with a vector of AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H indicating an adjacent network attack vector, low complexity, high privileges required, no user interaction, changed scope, and high confidentiality, integrity, and availability impact. EPSS exploitation probability is not available, and the vulnerability is not listed in CISA KEV nor accompanied by public proof-of-concept code. From an SSVC perspective, exploitation is none at present, but the exploit is automatable given low complexity and the technical impact is total. Real-world risk is moderate because while impact is critical, the required adjacency and high privileges limit the attack surface. The risk is not merely a high-CVSS theoretical issue but its exploitation depends on an already compromised high-privilege account and network adjacency to the management network.

Exploit ScenarioDerived

An attacker who has obtained high-privilege credentials (e.g., administrator) to the LoadMaster management interface and is positioned on the adjacent network sends a crafted request to the Geo Location configuration endpoints. The injected operating system command executes with the appliance's underlying OS privileges, granting the attacker full control over the system.

AnalysisAIv1 – Jul 27, 2026

OS command injection in Progress LoadMaster and related products allows authenticated high-privilege attackers to execute arbitrary operating system commands via the Geo Location management interface, resulting in complete system compromise. Affected products include LoadMaster, ECS Connection Manager, Object Scale Connection Manager, and MOVEit WAF. No public exploit or active exploitation was identified at the time of analysis.

RemediationAI

Vendor-released patches are available; consult the advisory at the provided URL to upgrade to the latest fixed version. If immediate patching is not possible, restrict access to the Geo Location management interface to trusted management segments only, enforce strict authentication and privilege controls for administrative accounts, and monitor for unexpected command execution on the appliance. Note that restricting interface access is a compensating control that does not eliminate the underlying injection flaw if an administrative account is compromised.

Technical ContextAI · show details

The vulnerability resides in the Geo Location management functionality of affected Progress software appliances. The root cause is improper neutralization of special elements used in an OS command (CWE-78), allowing injection of operating system commands through unsanitized user-supplied input. The affected CPEs show the vulnerability spans multiple products from Progress Software that share this management interface. Successful exploitation can subvert the security scope, moving from the application context to the underlying operating system with full read, write, and availability impact.
