Navigate to the Net2 installation directory (usually C:\Program Files (x86)\Paxton Access\Centurion\ ). Right-click Net2Config.exe and select . Go to the Database tab. Step 3: Switch Authentication or Input New Credentials
A: Yes. Paxton has released multiple updates and service releases for Net2 that address the protocol flaws. This is why keeping your software updated is so critical. Modern versions also feature an improved, code-based password reset procedure for the System Engineer account.
Before performing the Paxton Net2 SQL database password repack, ensure that you have:
Place the Net2 server in a dedicated VLAN with strict firewall rules. Allow communication only with authorized client machines and required control units. The system operates in a client-server model, and the 2019 RCE vulnerability demonstrated that allowing untrusted clients to connect is dangerous.
If prompted, you must contact Paxton Technical Support to receive a unique reset code. paxton net2 sql database password repack
Inside the Database tab, you can alter how Net2 binds to SQL Server:
Managing the SQL database password generally refers to one of two things: resetting the System Engineer credentials or managing the underlying SQL Server (SA) account . Because the SQL database contains all user and event data, maintaining secure, updated passwords is a critical security requirement. 1. Resetting the Net2 System Engineer Password
: An attacker requires local access to the computer running the Net2 software. However, researchers noted that this can also be achieved remotely via remote desktop tools such as AnyDesk, making physical access unnecessary.
Older versions historically utilized a local Microsoft Access database ( .mdb ) or a highly integrated SQL Server Express instance. Step 3: Switch Authentication or Input New Credentials

Run this SQL query regularly to see if any backdoor users have been added by a repack:
When installing or upgrading Net2, the system establishes a connection to a Microsoft SQL Server instance (typically SQL Express) to store user, event, and configuration data. The connection details, including the username and password, are stored securely, often encrypted within the Net2 configuration files. A "repack" or password reset scenario occurs when:
: This obfuscated string is decoded by the client and can be recovered by reversing the algorithm or dumping client memory, potentially granting an attacker direct database credentials. Reconnecting the Net2 Software
Searching for the term reveals a niche but active segment of the security community. Users looking for this phrase typically fall into three categories:
The keyword represents a highly technical cross-section of physical security management, SQL database administration, and reverse engineering. When a system administrator or security professional searches for this exact combination of terms, they are typically trying to solve a critical issue: regaining access to a lost, locked, or corrupted Paxton Net2 access control database by manipulating the underlying Microsoft SQL Server deployment.
Older versions of Net2 used SQL Server Authentication with a hardcoded or systematically generated system administrator ( sa ) or Net2 user password. Newer versions lean toward Windows Authentication or dynamically generated unique instance passwords during installation to comply with modern security standards.
Recommended if your SQL server is on the same machine or domain. It removes the need to store a plaintext or static SQL password.
Type exit , stop the service, and restart it normally without the /m flag. Reconnecting the Net2 Software
