Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation for Client Execution (T1203). 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

Requires validation of information inputs, such as files during the import process, to prevent malicious files from overwriting critical internal files.

SI-2 Flaw Remediation good match

prevent

Mandates timely flaw remediation, including patching the arbitrary file overwrite vulnerability in the PDF Reader app's file import process.

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

detect

Enforces integrity checks on software and critical files to identify unauthorized modifications resulting from malicious file imports.

MITRE ATT&CK Enterprise TechniquesAI

T1203 Exploitation for Client Execution Execution

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

NVD Description

An arbitrary file overwrite vulnerability in Docudepot PDF Reader: PDF Viewer APP v1.0.34 allows attackers to overwrite critical internal files via the file import process, leading to arbitrary code execution or information exposure.

Deeper analysisAI

CVE-2026-30292 is an arbitrary file overwrite vulnerability (CWE-73) in Docudepot PDF Reader: PDF Viewer APP version 1.0.34. The issue arises during the file import process, where attackers can overwrite critical internal files, potentially leading to arbitrary code execution or information exposure. Published on 2026-04-01, 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), reflecting high confidentiality, integrity, and availability impacts.

A local attacker can exploit this vulnerability with low attack complexity, requiring no privileges or user interaction. By crafting a malicious file for import, the attacker overwrites essential internal files, achieving arbitrary code execution on the device or exposing sensitive information stored within the application.
