CVE-2025-59093
HighSummary
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.
Risk Assessment
An attacker can access the Exos 9300 database with permissions to read most tables and update/insert into many tables, potentially compromising data integrity and confidentiality.
Recommendation
Immediately change the database password generation method to a cryptographically secure one and rotate the password. Also restrict registry access to prevent unauthorized users from reading sensitive data.
Other vulnerabilities in Exos 9300
See all- CVE-2025-59092High
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.
- 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)
Exos 9300 instances are using a randomly generated database password to connect to the configured MSSQL server. The password is derived from static random values, which are concatenated to the hostname and a random string that can be read by every user from the registry. This allows an attacker to derive the database password and get authenticated access to the central exos 9300 database as the user Exos9300Common. The user has the roles ExosDialog and ExosDialogDotNet assigned, which are able to read most tables of the database as well as update and insert into many tables.
