Deep Thought Industries ACE Scanner PDF Scanner Arbitrary File Overwrite Vulnerability

A vulnerability allowing arbitrary file overwriting has been identified in Deep Thought Industries ACE Scanner PDF Scanner version 1.4.5. This issue arises from inadequate security validation during the file import process, enabling attackers to overwrite critical internal files. Such actions could lead to unauthorized code execution, exposure of sensitive information, denial of service, or other severe security consequences.

Impact

Exploitation of this vulnerability could result in overwriting executable or configuration files, potentially leading to arbitrary code execution, privilege escalation, or causing the application to malfunction or fail to launch.

Reproduction

The vulnerability can be reproduced by importing files through the ACE Scanner PDF Scanner app. A malicious app can be used to control the filename and content, employing path traversal techniques to overwrite sensitive files in the application's internal storage. Once the victim opens the malicious app, the overwriting occurs automatically, without requiring complex user interaction.
