CVE-2025-70093 Details
Description
An issue in OpenSourcePOS v3.4.1 allows attackers to execute arbitrary code via returning a crafted AJAX response.
A vulnerability in OpenSourcePOS version 3.4.1 allows for arbitrary code execution through the manipulation of AJAX responses. The issue arises because certain AJAX endpoints return JSON data with an incorrect Content-Type header, which can lead to stored Cross-Site Scripting (XSS) vulnerabilities. When user-controlled data is included in these responses, it is interpreted as HTML rather than JSON, enabling the execution of injected scripts in the context of the user's browser.
The Content-Type header for all AJAX endpoints returning JSON data should be explicitly set to 'application/json'. Additionally, user-controlled data included in AJAX responses should be properly encoded to prevent script execution.
