Lifecycle Timeline
6DescriptionCVE.org
The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.
AnalysisAI
Unlimited authentication attempts against the eParking.fi WebSocket API enable network-based denial-of-service attacks that suppress or mis-route electric vehicle charger telemetry, and enable credential brute-forcing to gain unauthorized system access. Reported by ICS-CERT, affecting all versions of the charging management platform. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires network access to the eParking.fi WebSocket API endpoint, typically exposed on TCP port 443 (WSS) or 80 (WS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk assessment requires reconciling conflicting signals across multiple frameworks. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Remote attacker identifies eParking.fi WebSocket endpoint via Shodan search for charging infrastructure APIs. Using automated brute-force tool, attacker submits 10,000 authentication attempts per minute using common credential lists (admin/admin, default charger passwords). … |
| Remediation | No vendor-released patch identified in CISA advisory or EUVD data at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all eParking.fi deployments and document current versions; implement network-level rate limiting on WebSocket API endpoints to restrict authentication attempts per source IP. …
