Executive Summary

CVE-2026-30287 is an arbitrary file overwrite vulnerability found in Deep Thought Industries ACE Scanner PDF Scanner version 1.4.5. The flaw exists in the file import process of the app, specifically in the component FileReaderSplashActivity, where insufficient security validation allows attackers to manipulate filenames and contents of imported files using path traversal techniques.

This manipulation enables attackers to overwrite critical internal files within the app’s storage, including executable and configuration files, which can lead to severe security issues.

Impact Analysis

Exploitation of this vulnerability can have multiple serious impacts including arbitrary code execution, which means attackers can run malicious code on the device.

It can also lead to exposure of sensitive information stored within the app, denial of service causing the app to malfunction or fail to launch, and privilege escalation allowing attackers to gain higher access rights.

The attack requires minimal user interaction and can be triggered automatically when a victim opens a malicious app, increasing the risk of compromise.

Detection Guidance

The vulnerability in ACE Scanner PDF Scanner v1.4.5 is due to an arbitrary file overwrite flaw in the file import process, which can be exploited via path traversal techniques. Detection involves monitoring for suspicious file import activities that manipulate filenames or paths to overwrite internal files.

Since the vulnerability is triggered when the victim opens a malicious app or imports a crafted file, detection can focus on identifying unusual file import operations or unexpected modifications to critical internal files within the app's storage.

Specific commands are not provided in the resources, but general approaches include:

• Monitoring file system changes in the app's storage directory for unexpected overwrites.
• Using Android debugging tools (adb) to check the app's file directories for suspicious files or altered configuration/executable files.
• Checking app logs for errors or unusual behavior related to file imports.
• Scanning for installed app version 1.4.5 of ACE Scanner to identify vulnerable installations.
