Summary

CVE-2025-0472 is a high-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Sigb Pmb. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 41.0th 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 SI-10 (Information Input Validation) and SI-11 (Error Handling).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly validates uploaded files to prevent unrestricted uploads of dangerous types that enable internal file enumeration.

SI-11 Error Handling good match

prevent

Ensures error handling in responses does not expose sensitive internal file paths or machine information during upload attempts.

SI-15 Information Output Filtering good match

prevent

Filters information outputs in request responses to block disclosure of internal files enumerated via the upload vulnerability.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

attack.mitre.org →

T1083 File and Directory Discovery Discovery

Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.

attack.mitre.org →

T1105 Ingress Tool Transfer Command And Control

Adversaries may transfer tools or other files from an external system into a compromised environment.

attack.mitre.org →

Why these techniques?

Vuln in public-facing PMB app enables unauth file upload (T1105) and internal file enumeration (T1083) via response inspection; directly exploitable as public app (T1190).

NVD Description

Information exposure in the PMB platform affecting versions 4.2.13 and earlier. This vulnerability allows an attacker to upload a file to the environment and enumerate the internal files of a machine by looking at the request response.

Deeper analysisAI

CVE-2025-0472 is an information exposure vulnerability in the PMB platform, affecting versions 4.2.13 and earlier. Published on 2025-01-16, the flaw allows an attacker to upload a file to the environment and enumerate internal files on the machine by inspecting the request response. It is linked to CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) and CWE-434 (Unrestricted Upload of File with Dangerous Type), 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), indicating high confidentiality impact.

An unauthenticated attacker (PR:N) can exploit this over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). By uploading a file and analyzing the response, the attacker achieves enumeration of internal files, resulting in significant information disclosure (C:H) without impacting integrity or availability.

The INCIBE-CERT advisory at https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-pmb-platform provides details on this and other vulnerabilities in the PMB platform, including recommended mitigations.
