Vulnerability Data
Teltonika’s Remote Management System versions prior to 4.10.0 have a feature allowing users to access managed devices’ local secure shell (SSH)/web management services over the cloud proxy. A user can request a web proxy and obtain a URL in the…

Remote Management System cloud subdomain. This URL could be shared with others without Remote Management System authentication . An attacker could exploit this vulnerability to create a malicious webpage that uses a trusted and certified domain. An attacker could initiate a reverse shell when a victim connects to the malicious webpage, achieving remote code execution on the victim device.

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.
Restricting mobile code technologies and monitoring their use blocks web functionality (e.g., scripts) loaded from untrusted sources.
Components that flag malicious websites reduce the ability to pull and render web functionality from untrusted external sources.
Mitigating Controls (NIST CSF 2.0) AI
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.
Contractual requirements can mandate vetting of web sources and prohibit untrusted inclusions.
Due diligence before supplier relationships directly prevents inclusion of untrusted web functionality.
Assessing supplier risks and products reduces the chance of embedding untrusted web widgets or scripts.
Integrity checks on acquired software can catch untrusted web functionality before use.
Supplier assessments prior to acquisition address the root risk of untrusted web sources.
Secure SDLC practices can include policies forbidding inclusion of untrusted external web code.
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.
Network security controls can restrict or block untrusted external web content, but do not specifically address inclusion of web widgets.
Web filtering can prevent loading of untrusted web functionality, directly mitigating the weakness.
A.8.26 only requires that security requirements (including resilience against attacks such as injections) be identified and specified during development or acquisition; it does not itself enforce, implement, or prevent any resulting untrusted web functionality from being included or exploited.
A.8.27 mandates security-by-design principles (defense-in-depth, least privilege, assume-breach, distrust external input, secure architecture review against attack patterns) that reach some but not most inclusion-of-untrusted-web-functionality cases; many real instances remain exploitable without further controls (e.g. CSP, sandboxing, or output sanitization).
Secure coding practices can avoid unsafe inclusion of external scripts, but coverage depends on developer adherence.
