Is this vulnerability remotely exploitable?

Yes. The vulnerable endpoint is accessible over the network, and exploitation involves sending crafted HTTP requests with malicious PGUID values to the application, subject to any authentication and network controls in place.

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

An attacker generally needs network-level access to the web interface and the ability to reach /SISReport/WebReport20/Proxy/AsyncTreeProxy.aspx. If the endpoint is not protected by authentication or strong access controls, unauthenticated exploitation may be possible depending on the deployment.

What is the safest general fix pattern for this vulnerability?

The most robust fix is to replace any dynamically constructed SQL that incorporates PGUID (or similar parameters) with parameterized queries or prepared statements, combined with strict input validation and least-privilege database access. This addresses the root cause rather than just mitigating specific payloads.
