CVE-2025-59092
HighSummary
An RPC service in exos 9300, run by FSMobilePhoneInterface.exe, is reachable on port 4000 and requires no authentication. This allows sending arbitrary status information, e.g., about door contacts, without prior login.
Risk Assessment
An attacker can manipulate the status of Access Managers, potentially causing false alarms or hiding real security events, compromising the integrity of physical monitoring.
Recommendation
Restrict access to port 4000 to trusted hosts only and implement authentication for the RPC service if feasible.
Other vulnerabilities in exos 9300
See all- CVE-2025-59093High
The vulnerability in Exos 9300 involves a randomly generated database password for MSSQL, derived from static random values concatenated with the hostname and a random string readable from the registry by any user. This allows an attacker to derive the password and gain authenticated access to the central database as user Exos9300Common.
- CVE-2025-59097Critical
The exos 9300 application configures Access Managers via a GUI. When saving, the whole configuration is sent via SOAP without any authentication or authorization by default. Optional security (IPsec, mTLS) is not enabled by default.
- CVE-2025-59091Critical
Multiple hardcoded credentials allow login to the exos 9300 datapoint server on ports 1004 and 1005. This server relays status information and can also control Access Managers, including opening doors.
- CVE-2025-59090Critical
The exos 9300 server exposes a SOAP API on port 8002 without authentication. This allows network attackers to create arbitrary access log events and query 2FA PINs associated with enrolled chip cards.
Original NVD description (English source)
An RPC service, which is part of exos 9300, is reachable on port 4000, run by the process FSMobilePhoneInterface.exe. This service is used for interprocess communication between services and the Kaba exos 9300 GUI, containing status information about the Access Managers. Interacting with the service does not require any authentication. Therefore, it is possible to send arbitrary status information about door contacts etc. without prior authentication.
