Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Enforces access-control policy on the sendsms.jsp endpoint so that only authorized actions are permitted on the File argument, directly blocking the unrestricted upload path.
Requires validation of all input (including uploaded File content and type) before processing, preventing acceptance of arbitrary or dangerous files.
Limits privileges of the low-privileged accounts that can reach /business/common/sms/sendsms.jsp so they cannot perform file-upload operations outside their assigned functions.
