Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

AC-7 Unsuccessful Logon Attempts
addresses: CWE-307

This control directly enforces limits on consecutive invalid logon attempts and automatic response (e.g., lockout) to prevent brute-force exploitation of authentication mechanisms.

IA-10 Adaptive Authentication
addresses: CWE-307

Specific conditions can include excessive failed attempts, triggering stronger authentication that restricts brute-force exploitation.

Security SummaryAI

CVE-2026-25113 is a vulnerability in the WebSocket Application Programming Interface that lacks restrictions on the number of authentication requests due to the absence of rate limiting. This issue affects components handling charger telemetry, as referenced in CISA ICS Advisory ICSA-26-057-06 and associated documentation from SWTCH Energy.

The vulnerability can be exploited by remote, unauthenticated attackers over the network with low attack complexity and no user interaction required. Attackers may conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or perform brute-force attacks to gain unauthorized access. The CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) reflects high availability impact, with CWE-307 (Improper Restriction of Excessive Authentication Attempts) as the underlying weakness.

Mitigation guidance is provided in CISA ICS Advisory ICSA-26-057-06 at https://www.cisa.gov/news-events/ics-advisories/icsa-26-057-06 and the corresponding CSAF JSON file at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-057-06.json.

MITRE ATT&CK Enterprise TechniquesAI

T1110 Brute Force Credential Access
Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.
attack.mitre.org →
T1110.001 Password Guessing Credential Access
Adversaries with no prior knowledge of legitimate credentials within the system or environment may guess passwords to attempt access to accounts.
attack.mitre.org →
T1110.003 Password Spraying Credential Access
Adversaries may use a single or small list of commonly used passwords against many different accounts to attempt to acquire valid account credentials.
attack.mitre.org →
T1499.002 Service Exhaustion Flood Impact
Adversaries may target the different network services provided by systems to conduct a denial of service (DoS).
attack.mitre.org →
Why these techniques?

Lack of auth rate limiting (CWE-307) directly enables brute-force/password guessing attacks (T1110 and subs) and service exhaustion DoS against telemetry (T1499.002).
