Summary

CVE-2025-13651 is a medium-severity Exposure of Sensitive System Information to an Unauthorized Control Sphere (CWE-497) vulnerability in Microcom360 Zeusweb. Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique System Information Discovery (T1082); ranked at the 33th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — 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-2025-13651 is an Exposure of Sensitive System Information to an Unauthorized Actor vulnerability in Microcom ZeusWeb version 6.1.31. The flaw enables web application fingerprinting of sensitive data, mapped to CWE-497. It carries 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), indicating high severity due to significant confidentiality impact.

Remote attackers require no privileges or user interaction to exploit this vulnerability over the network with low attack complexity. Successful exploitation allows unauthorized actors to fingerprint the web application and expose sensitive system information, potentially aiding further reconnaissance or targeted attacks.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces approved authorizations for logical access, directly stopping unauthorized actors from reaching sensitive system information.

AC-4 Information Flow Enforcement good match

Enforces information flow policies that block sensitive system data from crossing into unauthorized control spheres.

AC-6 Least Privilege good match

Limits privileges so that only the minimum necessary access is granted, reducing the chance of exposing system-level details.

SC-7 Boundary Protection partial match

Controls communications at external and key internal boundaries to keep sensitive system information inside authorized spheres.

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.

PR.AA-05 mostly match
prevents

Enforcing least-privilege access permissions directly prevents unauthorized actors from reaching sensitive system information.

PR.IR-01 mostly match
