CVE-2022-32994 An arbitrary file upload vulnerability was found in Halo CMS v1.5.3.

An attacker could leverage this vulnerability to execute code on the affected system or obtain sensitive information. The security risk of malicious file uploads is often increased on websites with limited user privileges. Fortunately, the Halo CMS v1.5.3 software has a feature that allows administrators to restrict which users are allowed to upload files. In order to exploit this issue, an attacker would have to either convince an admin to upload a malicious file or craft a malicious file that would be allowed to upload. An attacker could also host a malicious PHP file on a server and use a web proxy or browser plugin to upload the file.

Vulnerability overview

A malicious file upload vulnerability was discovered in the Halo CMS v1.5.3 software. It is possible for an attacker to trick an admin into uploading a malicious file or craft a malicious file that would be allowed to upload. The security risk of malicious file uploads is often increased on websites with limited user privileges. Fortunately, the Halo CMS v1.5.3 software has a feature that allows administrators to restrict which users are allowed to upload files. In order to exploit this issue, an attacker would have to either convince an admin to upload a malicious file or craft a malicious file that would be allowed to upload.

Vulnerability Discovery and Description

This software flaw is caused by a PHP file not properly verifying uploaded files, which could lead to the execution of arbitrary code on the affected system or data disclosure.

Microsoft Office Document Parsing Vulnerability

In early February, Microsoft released security advisory (SA) 2022-32994 to address a vulnerability in the parsing of Office documents. The vulnerability is found in the Microsoft Office Document Parsing Library (MDAC) and allows an attacker to execute code on the affected system or obtain sensitive information. This issue can be exploited via malicious documents that are allowed to upload via Windows file sharing.
This article will discuss how to mitigate this issue by implementing appropriate network segmentation with Halo CMS v1.5.3 software, restricting which users have access to specific web panels, and requiring authentication for file uploads.
