CVE-2026-109106

Description

A flaw was found in Polaris Office. A local attacker can supply a crafted file name argument to the document intake component to trigger a path traversal vulnerability. This issue allows the attacker to create or overwrite files outside the intended temporary directory, resulting in unauthorized file modification.

Statement

This vulnerability is evaluated as having Moderate impact because exploitation requires local access and only permits unauthorized file modification within the context of the mobile application. Polaris Office is an application developed for mobile platforms and is not packaged or distributed with any Red Hat software. Consequently, Red Hat enterprise products and services are not exposed to or affected by this issue.

Understanding the Weakness (CWE)

Integrity,Confidentiality,Availability

Technical Impact: Execute Unauthorized Code or Commands

The attacker may be able to create or overwrite critical files that are used to execute code, such as programs or libraries.

Integrity

Technical Impact: Modify Files or Directories

The attacker may be able to overwrite or create critical files, such as programs, libraries, or important data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, appending a new account at the end of a password file may allow an attacker to bypass authentication.

Confidentiality

Technical Impact: Read Files or Directories

The attacker may be able to read the contents of unexpected files and expose sensitive data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, by reading a password file, the attacker could conduct brute force password guessing attacks in order to break into an account on the system.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

The attacker may be able to overwrite, delete, or corrupt unexpected critical files such as programs, libraries, or important data. This may prevent the product from working at all and in the case of protection mechanisms such as authentication, it has the potential to lock out product users.
