Vulnerability Data
Insufficient input validation vulnerability in NETGEAR JR6150 (AC750 WiFi Router 802.11ac Dual Band Gigabit released in 2014) allows administrators connected to the local network to make unauthorized modification of router software and functionality. NETGEAR JR6150 reached End-of-Support status in 2018…

Mitigating Controls (NIST 800-53 r5) AI
Directly requires input validation on all external inputs to block the unauthorized software/functionality modifications described in CWE-20.
Mandates replacement of the EoS JR6150 (unsupported since 2018) whose lack of patches leaves the input-validation flaw permanently exposed.
Requires integrity verification of firmware and configuration to detect or block unauthorized modifications attempted via the flawed input paths.

Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.
Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.
Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.
Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.
Requiring language-specific secure coding standards, peer review, SAST and documented mitigation of common programming errors forces validation of all inputs before they are trusted.
Regular automated validation of system software and data content, combined with scanning of all inbound files, enforces input validation at the boundary before untrusted content is processed.
