Is this vulnerability remotely exploitable?

Yes. An attacker can exploit it remotely by sending or embedding a crafted URL that includes a malicious sccs parameter, causing code execution in the victim's browser when the link is opened.

What level of access does an attacker need?

The attacker primarily needs the ability to deliver a malicious link to a user of the WeGIA application. If the targeted page is accessible without special privileges, no additional access is required beyond the victim's normal session.

What is the safest general fix pattern for this issue?

Replace any direct output of request parameters with context-appropriate encoding, and where possible, map status indicators (like msg and sccs) to server-side enumerated messages instead of reflecting arbitrary strings from the client.
