Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 1.22% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Schneider Electric APC Easy UPS Online Monitoring Software (Windows 10, 11 Windows Server 2016, 2019, 2022) and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Summary
CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability exists that could cause remote code execution when manipulating internal methods through Java RMI interface.
Remediation
Version v2.6-GA-01-23116 of Schneider Electric Easy UPS Online Monitoring Software includes a fix for the vulnerabilities for Microsoft supported versions of Windows (10, 11) and Windows Server (2016, 2019, 2022) and is available for direct download here: https://download.schneider-electric.com/files?p_enDocType=Software+- +Release&p_Doc_Ref=APC_install_APC_UPS_windows The Easy UPS Online Monitoring Software has been discontinued coinciding with the discontinuation of the Easy UPS Online SNMP Cards (APV9601, APVS9601) managed by this software. Note: The fix applies to all variants of UPS Online Monitoring Software. It is recommended that customers currently using Easy UPS Online Monitoring Software to manage Easy UPS Online (SRV/SRVS) to transition to PowerChute Serial Shutdown for serial/USB shutdown and monitoring; and to PowerChute Network Shutdown for network shutdown and monitoring.

What, why and how

CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability exists that could cause remote code execution when manipulating internal methods through Java RMI interface.

What

CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability exists that could cause remote code execution when manipulating internal methods through Java RMI interface.

Why

Untrusted input is incorporated into an operating-system command without safe parameter handling.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may execute code or commands in the affected security context.

What

CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability exists that could cause remote code execution when manipulating internal methods through Java RMI interface.

Why

Untrusted input is incorporated into an operating-system command without safe parameter handling.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may execute code or commands in the affected security context.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') → execute code or commands in the affected security context
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction
None
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-78 ↗

CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'). The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.
