Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly prevents exploitation by requiring validation of file inputs during the import process to block malicious files enabling arbitrary overwrites of critical internal files.

SI-2 Flaw Remediation good match

prevent

Mitigates the specific flaw in TA/UTAX Mobile Print v3.7.2.251001 by identifying, prioritizing, and remediating the arbitrary file overwrite vulnerability.

SI-7 Software, Firmware, and Information Integrity partial match

preventdetect

Verifies the integrity of critical internal files to prevent execution of overwritten code or detect unauthorized modifications post-import.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

T1203 Exploitation for Client Execution Execution

Adversaries may exploit software vulnerabilities in client applications to execute code.

Why these techniques?

Arbitrary file overwrite (path traversal) in a client PDF app directly enables local exploitation for code execution (T1203) and associated privilege escalation (T1068) by overwriting internal binaries/configs during import with no user interaction or privileges required.

NVD Description

An arbitrary file overwrite vulnerability in PDF Reader App : TA/UTAX Mobile Print v3.7.2.251001 allows attackers to overwrite critical internal files via the file import process, leading to arbitrary code execution or information exposure.

Deeper analysisAI

CVE-2026-30277 is an arbitrary file overwrite vulnerability, classified under CWE-22, affecting the PDF Reader App within TA/UTAX Mobile Print version 3.7.2.251001. The flaw enables attackers to overwrite critical internal files during the file import process, which can result in arbitrary code execution or information exposure. Published on 2026-03-31, it carries a CVSS v3.1 base score of 8.4 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact with relatively low barriers to exploitation.

A local attacker can exploit this vulnerability with low complexity and no required privileges or user interaction. By crafting a malicious file for import, the attacker overwrites essential internal files, achieving high levels of confidentiality, integrity, and availability disruption, such as executing arbitrary code on the affected system or exposing sensitive data.
