Is this vulnerability remotely exploitable?

Yes, but only by authenticated users who possess file editor or equivalent permissions. Once such access is obtained, exploitation can be done remotely over HTTP by creating and executing a malicious PHP file.

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

The attacker needs a valid CI4MS account with file editor permissions or another role capable of creating and saving files via the affected endpoints. Without such permissions, direct exploitation via the described vector is not feasible.

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

The safest pattern is to ensure that no user-facing feature—regardless of authentication level—can write executable code to locations interpreted by the server. This means restricting file editors to non-executable areas, enforcing strict allowlists for file types and paths, and designing the deployment pipeline so that code changes require out-of-band deployment rather than in-app editing.
