Version | System | Solution Description |
| 3.0.0 and higher | SP8 | Please contact your Leica Technical Support to implement the update to version 3.5.7. If you do not want to update your software at the moment, please follow the instructions below to block the TCP port 22350. To stop attackers from being able to exploit the vulnerability, the TCP port 22350 needs to be blocked in the network communication. It can be done either in your local Windows system (instructions for LAS X and PAULA and instructions for LMD instruments) or in your organization’s network firewall system. Please contact your IT admin for support to block the TCP port 22350. Once this port is blocked, you can continue working with your imaging software. In case activation of licenses might be blocked, please use the file-based activation via e-mail. |
