Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 2.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement).

Deeper analysis

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

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Directly enforces access control policies to block unauthenticated remote actors from retrieving sensitive system information exposed by ZeusWeb 6.1.31.

AC-4 Information Flow Enforcement good match
prevent

Enforces information flow policies that would stop the unauthorized release of internal system details used for web application fingerprinting.

SC-7 Boundary Protection partial match
prevent

Boundary protection mechanisms can filter or restrict network traffic that would otherwise allow unauthenticated exposure of sensitive ZeusWeb data.
