CVE-2025-10067 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of the itsourcecode POS Point of Sale System. The vulnerability resides in an unspecified function within the file /inventory/main/vendors/datatables/unit_testing/templates/empty_table.php. Specifically, the issue arises from improper sanitization or validation of the 'scripts' argument, which can be manipulated by an attacker to inject malicious scripts. This vulnerability is remotely exploitable without requiring authentication, and user interaction is necessary to trigger the malicious payload. The vulnerability has a CVSS 4.0 base score of 5.3, indicating a medium severity level. 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 initial attack vector (UI:P indicates user interaction is needed to trigger the payload). The impact primarily affects the integrity of the victim's session or data, with limited impact on confidentiality and availability. The vulnerability does not require special conditions such as scope changes or privileges, and no known exploits are currently observed in the wild. However, the exploit code is publicly available, increasing the risk of exploitation. Given that this vulnerability affects a POS system, it could be leveraged to execute malicious scripts in the context of the POS web interface, potentially leading to session hijacking, data manipulation, or phishing attacks targeting employees or administrators using the system.

For European organizations using the itsourcecode POS Point of Sale System version 1.0, this vulnerability poses a risk of client-side script injection attacks. Successful exploitation could allow attackers to execute arbitrary JavaScript in the context of the POS system's web interface, potentially leading to theft of session cookies, unauthorized actions within the POS system, or delivery of further malware payloads. This could disrupt sales operations, compromise transaction integrity, or expose sensitive customer payment data indirectly through social engineering or session hijacking. Given the critical role of POS systems in retail and hospitality sectors, exploitation could result in financial losses, reputational damage, and regulatory compliance issues under GDPR if customer data is indirectly affected. The medium severity score reflects that while the vulnerability is exploitable remotely and without authentication, the impact on confidentiality and availability is limited. However, the integrity impact and potential for social engineering make it a significant concern for organizations relying on this POS system in Europe.

1. Immediate patching: Organizations should monitor itsourcecode vendor communications for patches or updates addressing CVE-2025-10067 and apply them promptly once available. 2. Input validation and sanitization: Until a patch is released, implement web application firewall (WAF) rules to detect and block suspicious payloads targeting the vulnerable 'scripts' argument in the specified PHP file path. 3. Restrict access: Limit network exposure of the POS system's web interface to trusted internal networks or VPNs to reduce remote attack surface. 4. User training: Educate employees and administrators on recognizing phishing attempts or suspicious activities that could leverage XSS for social engineering. 5. Logging and monitoring: Enable detailed logging of web requests to the POS system and monitor for anomalous script injection attempts or unusual user behavior. 6. Segmentation: Isolate the POS system network segment from other critical systems to contain potential compromise. 7. Incident response readiness: Prepare response plans to quickly address any detected exploitation attempts, including forensic analysis and system restoration.
