Vulnerability Data
Version 00.07.03.4 and prior of Teltonika’s RUT router firmware contain a packet dump utility that contains proper validation for filter parameters. However, variables for validation checks are stored in an external configuration file. An authenticated attacker could use an exposed…

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
The policy and procedures establish internal controls and change management for system configuration settings, reducing the feasibility of external unauthorized modifications.
Baseline configuration under change control directly prevents unauthorized external modification of system or configuration settings.
Requires approval, documentation, and security impact review of all configuration changes, directly preventing unauthorized external control of system settings.
Impact analysis of configuration changes reduces the risk of deploying settings that permit unauthorized external control.
Restricting changes to system and configuration settings prevents external entities from controlling those settings without approval.
Establishing, implementing, approving deviations from, and monitoring configuration settings directly prevents external or unauthorized control of system settings.
The plan defines processes for identifying and managing configuration items, preventing external unauthorized control of system settings.
Vulnerability scanners directly detect externally controllable or misconfigured settings using standardized checklists.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Hardened configuration baselines and change controls directly limit external manipulation of settings.
Formal change and exception management catches externally driven configuration alterations.
Least-privilege access policies reduce unauthorized external modification of configuration values.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Configuration management directly prevents external tampering with system settings.
Access rights assignment determines who may change system settings.
Privileged access rights reduce the number of users who can alter configuration.
Information access restriction limits who can view or modify configuration data.
Change management enforces controlled, authorized modifications to settings.
Access control policies underpin the technical restrictions on configuration changes.
