CVE-2026-49185: Instruction Injection via FieldX MDM
The FieldX MDM adb messaging topic passes unverified payloads directly into Runtime.exec(), allowing command/instruction injection.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Validate and sanitize all payloads received on the adb messaging topic before using them. Do not pass untrusted input directly into Runtime.exec(); implement input validation, command whitelisting, escape or reject dangerous characters, and prefer safer execution methods (e.g., invoking commands with argument arrays rather than via a shell).
FieldX MDM adb messaging topic handling = validate and sanitize payloads; do not execute untrusted input - Configuration
If the adb messaging topic is not required, disable it. If it is required, restrict publishing to authenticated and authorized/trusted publishers only and enforce strict access controls on who can send messages to that topic.
FieldX MDM adb messaging topic = disabled or restricted to trusted publishers - Compensating control
Restrict network and management access to the device/messaging endpoints: limit access to the adb/messaging interface to trusted IPs and networks via firewall/ACLs, place the management plane behind network isolation (VPN/VPC), and monitor logging/alerts for suspicious command execution attempts.
