Summary
CVE-2019-25706 is a high-severity Insertion of Sensitive Information into Externally-Accessible File or Directory (CWE-538) vulnerability in I8I (inferred from references). Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 44th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-16 (Security and Privacy Attributes) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2019-25706 is an unauthenticated file disclosure vulnerability in the Across DR-810 router. It allows remote attackers to download the rom-0 backup file, which contains sensitive information including router passwords and other configuration data, by sending a simple GET request to the rom-0 endpoint without any authentication. The vulnerability is rated with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and is associated with CWE-538 (Insertion of Sensitive Information into Log File).
Remote attackers with network access to the affected router can exploit this vulnerability without privileges or user interaction. By accessing the rom-0 endpoint via a GET request, they can retrieve the backup file, decompress it, and extract sensitive data such as passwords and configuration details, potentially enabling further network compromise or lateral movement.
Advisories and references, including the Vulncheck advisory on the Across DR-810 rom-0 unauthenticated file disclosure and an Exploit-DB entry (exploit 46132), document the issue, with the latter providing a proof-of-concept exploit. Additional details are available at http://www.ac.i8i.ir/. No specific patch or mitigation details are outlined in the provided information.

Mitigating Controls (NIST 800-53 r5) AI
Enforces per-object authorizations so that even if a file or directory is reachable, the sensitive contents remain inaccessible to unauthorized actors.
Associates sensitivity labels with data objects so that subsequent storage or flow decisions can enforce that only appropriately protected files or directories receive the data.
Controls information flows between objects, directly stopping sensitive data from being written into locations whose ACLs or visibility would expose it.
Requires confidentiality protection of information at rest, which can be implemented by restricting storage locations or encrypting contents that would otherwise be placed in externally visible files.
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.
Least-privilege file and directory permissions directly prevent unauthorized actors from reading sensitive data placed in accessible locations.
Protecting data-at-rest encompasses file-level access controls and encryption that stop exposure of sensitive information in externally reachable paths.
Hardened configuration baselines and ongoing config management reduce the chance that sensitive data is written to world-readable files or directories.
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.
Requiring visible or metadata labels on classified information helps ensure that files placed in externally accessible locations still carry an explicit sensitivity marker, lowering the likelihood of unnoticed exposure.
The control’s requirement to remove or securely destroy information stored in externally accessible locations reduces the risk of sensitive data being left in files or directories that external parties can reach.
By ensuring that only the minimum necessary data is present in files or directories that may be reachable by external parties, the control lowers the impact of any subsequent exposure.
Verifying and sanitizing equipment prior to disposal or resale prevents sensitive files or directories from remaining accessible to external parties who later obtain the hardware.
