Detailsinfo

A vulnerability, which was classified as problematic, was found in Open Source Point of Sale up to 3.4.1. Affected is some unknown processing of the component Configuration Handler. The manipulation of the argument Return Policy with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. CVE summarizes:

Open Source Point of Sale (opensourcepos) is a web based point of sale application written in PHP using CodeIgniter framework. Starting in version 3.4.0 and prior to version 3.4.2, a Stored Cross-Site Scripting (XSS) vulnerability exists in the "Return Policy" configuration field. The application does not properly sanitize user input before saving it to the database or displaying it on receipts. An attacker with access to the "Store Configuration" (such as a rogue administrator or an account compromised via the separate CSRF vulnerability) can inject malicious JavaScript payloads into this field. These payloads are executed in the browser of any user (including other administrators and sales staff) whenever they view a receipt or complete a transaction. This can lead to session hijacking, theft of sensitive data, or unauthorized actions performed on behalf of the victim. The vulnerability has been patched in version 3.4.2 by ensuring the output is escaped using the `esc()` function in the receipt template. As a temporary mitigation, administrators should ensure the "Return Policy" field contains only plain text and strictly avoid entering any HTML tags. There is no code-based workaround other than applying the patch.

The advisory is available at github.com. This vulnerability is traded as CVE-2025-68147 since 12/15/2025. The exploitability is told to be easy. It is possible to launch the attack remotely. Additional levels of successful authentication are necessary for exploitation. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1059.007 by the MITRE ATT&CK project.

Upgrading to version 3.4.2 eliminates this vulnerability.
