ENISA EUVD identifier

EUVD-2026-68455

No EUVD known-exploited evidence

Attackers can exploit command injection vulnerabilities to delete core system runtime files, causing the monitoring module to crash and become paralyzed; simultaneously, they can obtain root privileges to steal configuration passwords such as SNMP, thereby tampering with critical system parameters and triggering abnormal operation of the entire power system.

Known exploitation
Not present in the current ENISA EUVD known-exploited dataset. This is not proof of no exploitation.

01

What, why and how

Attackers can exploit command injection vulnerabilities to delete core system runtime files, causing the monitoring module to crash and become paralyzed; simultaneously, they can obtain root privileges to steal configuration passwords such as SNMP, thereby tampering with critical system parameters and triggering abnormal operation of the entire power system.

What

Attackers can exploit command injection vulnerabilities to delete core system runtime files, causing the monitoring module to crash and become paralyzed; simultaneously, they can obtain root privileges to steal configuration passwords such as SNMP, thereby tampering with critical system parameters and triggering abnormal operation of the entire power system.

Why

The affected component does not establish the requesting party's identity reliably before granting access.

How

An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

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
an adjacent network → Improper Authentication → disrupt the affected service
Attack surface
Adjacent
Privileges required
None: unauthenticated exploitation is possible
User interaction

Attack complexity
Low: no specialised conditions are recorded
Security boundary
Changed: exploitation can affect a different security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-287 ↗

CWE-287: Improper Authentication. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

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

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

AVAdjacentAttack vector: The attacker must be on an adjacent or logically close 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.SChangedScope: The attack can affect a component governed by a different security 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
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
