Summary

A remote unauthenticated attacker can exploit a SQL injection vulnerability in PROCON-WEB SCADA to execute arbitrary commands.

General Recommendation

As a general security measure, Weidmueller strongly recommends to change the default passwords and to minimize the network exposure of products. Limit access to trusted networks by using the appropriate mechanisms.

Impact

Successful exploitation allows an unauthenticated attacker to read, modify or delete data and to execute arbitrary SQL commands, potentially leading to further compromise of the underlying system.

Remediation

It is strongly advised to update PROCON-WEB SCADA to version 6.11.3.
