Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict local access and enforce least privilege on affected hosts.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Schneider Electric Easergy Builder Installer and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

- Schneider Electric Easergy Builder installer version 1.7.23 and prior
- Summary
- A CWE-427 - Uncontrolled Search Path Element vulnerability exists that could allow an attacker with a local privileged account to place a specially crafted file on the target machine, which may give the attacker the ability to execute arbitrary code during the installation process initiated by a valid user.
- Remediation
- For customers newly installing systems that require Easergy Builder or customers who are modifying their systems and need to reinstall Easergy Builder, use the latest version (V1.7.24 or later of Easergy Builder): https://www.se.com/ww/en/download/document/Easergy_Builder/
Medium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority.

What, why and how
A CWE-427 - Uncontrolled Search Path Element vulnerability exists that could allow an attacker with a local privileged account to place a specially crafted file on the target machine, which may give the attacker the ability to execute arbitrary code during the installation process initiated by a valid user. Affected Products: Easergy Builder Installer (1.7.23 and prior)
What
A CWE-427 - Uncontrolled Search Path Element vulnerability exists that could allow an attacker with a local privileged account to place a specially crafted file on the target machine, which may give the attacker the ability to execute arbitrary code during the installation process initiated by a valid user. Affected Products: Easergy Builder Installer (1.7.23 and prior)
Why
The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.
How
An attacker operating through local access may attempt exploitation with elevated privileges. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.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 None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.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
- local access → Uncontrolled Search Path Element → execute code or commands in the affected security context
- Attack surface
- Local
- Privileges required
- High: elevated access is required
- User interaction

- Attack complexity
- High: exploitation depends on specific conditions

CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-427 ↗
CWE-427: Uncontrolled Search Path Element. The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.
- CVSS vector

CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity. CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:HCommon Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACHighAttack complexity: Successful exploitation depends on specific conditions outside the attacker's direct control.PRHighPrivileges required: The attacker needs elevated or administrative privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.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.

Patch and workaround
Operational remediation based on structured source evidence.
- Status
?
Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change. - Patch available
- Action
- For customers newly installing systems that require Easergy Builder or customers who are modifying their systems and need to reinstall Easergy Builder, use the latest version (V1.7.24 or later of Easergy Builder): https://www.se.com/ww/en/download/document/Easergy_Builder/
- Workaround
- No verified workaround is recorded. Limit untrusted access and use least privilege until authoritative guidance is available.
