CVE-2022-38731 Explained : Impact and Mitigation

This article provides detailed information about CVE-2022-38731, a vulnerability in Qaelum DOSE software that allows Directory Traversal via a specific parameter.

Understanding CVE-2022-38731

CVE-2022-38731 is a security vulnerability identified in Qaelum DOSE software versions 18.08 through 21.1, prior to version 21.2. The vulnerability allows attackers to perform Directory Traversal via a specific parameter, potentially leading to unauthorized access to sensitive files.

What is CVE-2022-38731?

The vulnerability in Qaelum DOSE software versions 18.08 through 21.1 before 21.2 allows Directory Traversal via the loadimages name parameter. Attackers can specify an arbitrary location on the server's filesystem from which to load an image, potentially enabling them to access unauthorized files.

The Impact of CVE-2022-38731

Exploiting this vulnerability can allow an attacker to enumerate files on the local system and request remote resources via a UNC path. This could lead to the disclosure of sensitive information and potentially coerce authentication from the server.

Technical Details of CVE-2022-38731

The following technical details outline the specific aspects of CVE-2022-38731:

Vulnerability Description

The vulnerability in Qaelum DOSE software allows Directory Traversal via the loadimages name parameter, enabling attackers to specify an arbitrary location on the server's filesystem and potentially access unauthorized files.
