Is this vulnerability remotely exploitable over the internet?

Yes, it can be exploited remotely, but only by someone who can access the administrative interface and perform a database restore. If administrative access is exposed to the internet and can be obtained via an authentication bypass or weak credentials, remote attackers can achieve full code execution.

What level of access does an attacker need to exploit this issue?

The attacker needs administrative-level access to the WeGIA web interface, specifically the ability to upload backup files and trigger the restore function. That access might be gained legitimately, through account compromise, or via another vulnerability such as an authentication bypass.

What is the safest general fix pattern for this type of vulnerability?

The most robust fix is to remove shell-based command construction from the restore workflow and rely on safe, parameterized APIs or libraries for database operations. Additionally, the application should completely decouple user-supplied filenames from internal command parameters by generating trusted server-side names and enforcing strict validation.
