CVE-2025-10063 is a medium-severity Cross Site Scripting (XSS) vulnerability identified in the itsourcecode POS Point of Sale System version 1.0. The vulnerability resides in the file /inventory/main/vendors/datatables/unit_testing/templates/deferred_table.php, specifically involving the manipulation of the 'scripts' argument. This flaw allows an attacker to inject malicious scripts that are executed in the context of the victim's browser. The vulnerability is remotely exploitable without requiring authentication, and user interaction is necessary to trigger the malicious payload. The CVSS 4.0 base score is 5.3, reflecting a moderate risk. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction required for the attack to be initiated (UI:P). The impact is limited primarily to integrity (VI:L) with no direct impact on confidentiality or availability. The vulnerability does not affect system components such as confidentiality or availability directly but can be leveraged to execute arbitrary JavaScript code, potentially leading to session hijacking, defacement, or redirection to malicious sites. Although no known exploits are currently observed in the wild, public exploit code is available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the itsourcecode POS system, which is used in retail environments for transaction processing and inventory management. The affected component is part of the user interface rendering logic, which processes input parameters insecurely, leading to the XSS flaw. This vulnerability highlights the importance of proper input validation and output encoding in web applications, especially in critical systems like POS platforms that handle sensitive customer and payment data.

For European organizations using the itsourcecode POS Point of Sale System version 1.0, this vulnerability poses a moderate risk. Successful exploitation could allow attackers to execute malicious scripts in the context of POS system users, potentially leading to theft of session tokens, unauthorized actions, or redirection to phishing sites. This could result in financial fraud, data leakage, or reputational damage. Since POS systems are often connected to payment processing networks, compromise could also lead to indirect impacts on payment data security and compliance with regulations such as GDPR and PCI DSS. The vulnerability's remote exploitability without authentication increases the attack surface, especially for POS systems exposed to internal networks or remote management interfaces. However, the requirement for user interaction (UI:P) somewhat limits the ease of exploitation. The impact on availability is negligible, but integrity and confidentiality risks exist due to possible session hijacking or manipulation of displayed data. European retailers and service providers relying on this POS system should consider this vulnerability seriously to prevent potential exploitation that could disrupt business operations and customer trust.

1. Immediate upgrade or patching: Organizations should check for any available patches or updates from itsourcecode addressing CVE-2025-10063. If no official patch exists, consider applying temporary mitigations such as disabling or restricting access to the vulnerable component (/inventory/main/vendors/datatables/unit_testing/templates/deferred_table.php). 2. Input validation and output encoding: Implement strict server-side input validation to sanitize the 'scripts' parameter and any other user-controllable inputs. Employ context-aware output encoding to prevent script injection in HTML contexts. 3. Web Application Firewall (WAF): Deploy or update WAF rules to detect and block attempts to exploit this XSS vulnerability by filtering malicious payloads targeting the vulnerable parameter. 4. Network segmentation: Limit exposure of POS systems by isolating them from public networks and restricting access to trusted users only. 5. User awareness and monitoring: Train staff to recognize phishing or suspicious links that could trigger XSS attacks and monitor logs for unusual activity related to the vulnerable endpoint. 6. Incident response readiness: Prepare to respond to potential exploitation attempts by having forensic and remediation plans in place. 7. Consider replacing or upgrading the POS system if it is no longer supported or if patches are unavailable, to reduce long-term risk.
