CVE-2026-25823
CriticalSummary
Urządzenia HMS Networks Ewon Flexy z firmware przed 15.0s4, Cosy+ z firmware 22.xx przed 22.1s6 oraz Cosy+ z firmware 23.xx przed 23.0s3 mają podatność na przepełnienie bufora stosu, co prowadzi do odmowy usługi. Ta podatność może być również wykorzystana do zdalnego wykonania kodu bez uwierzytelnienia.
Risk Assessment
Organizacja narażona jest na ryzyko odmowy usługi oraz potencjalnego zdalnego wykonania złośliwego kodu, co może prowadzić do poważnych konsekwencji dla bezpieczeństwa systemów.
Recommendation
Zaleca się aktualizację firmware urządzeń do najnowszych wersji, aby usunąć tę podatność oraz zminimalizować ryzyko związane z jej wykorzystaniem.

PHPNuxBill through 2025.3.20 contains an account takeover vulnerability in the customer password reset flow in system/controllers/forgot.php. An unauthenticated attacker can brute-force the 6-digit otp_code without attempt limits or lockout, then read the newly set password from the HTTP response to hijack the account.

PHPNuxBill through 2025.3.20 contains an unauthenticated SQL injection vulnerability in the radius.php FreeRADIUS REST endpoint that interpolates request parameters into whereRaw() queries. Attackers can send crafted username, macAddr or nasid parameters to the accounting or authenticate actions to extract customer records and credentials via time-based blind SQL injection.

Nginx UI is a web user interface for the Nginx web server. From 2.3.8 until 2.5.0, an authenticated administrator with an active secure session can submit attacker-controlled portable backup key material and a matching manifest to POST /api/restore. The restore flow trusts the supplied key, decrypts attacker-controlled contents, and replaces the live app.ini, including protected nginx command settings such as TestConfigCmd. Triggering POST /api/nginx/test then executes the restored command in the Nginx UI runtime context, affecting confidentiality, integrity, and availability.

The published Docker image for openPDC includes a fixed administrative credential with no forced change on first use. An attacker with network access to the management interface can authenticate using this credential and gain full administrative control of the application.
- CVE-2026-100730Critical
A service console interface on openPDC and openHistorian deserializes a client-supplied data structure. On systems using Windows Authentication, an attacker must already be authenticated to reach this function; on systems without Windows Authentication, this is reachable by an unauthenticated network attacker. This allows an attacker to trigger deserialization of an arbitrary object graph, which could allow remote code execution under the privileges of the affected service account.
