CVE-2025-10027 is a cross-site scripting (XSS) vulnerability identified in the itsourcecode POS Point of Sale System version 1.0. The vulnerability exists in an unspecified functionality within the file /inventory/main/vendors/datatables/unit_testing/templates/2512.php. Specifically, the issue arises from improper handling and sanitization of the 'scripts' argument, which allows an attacker to inject malicious scripts. This vulnerability can be exploited remotely without requiring authentication, although user interaction is necessary to trigger the malicious payload. The vulnerability has been publicly disclosed, increasing the risk of exploitation, but no known exploits are currently reported in the wild. The CVSS 4.0 base score is 5.1, indicating a medium severity level. The vector string (AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P) shows that the attack can be launched over the network with low attack complexity, no privileges required, but user interaction is needed. The impact primarily affects the confidentiality and integrity of user sessions or data accessible via the POS system's web interface, potentially allowing attackers to execute arbitrary scripts in the context of the victim's browser. This could lead to session hijacking, data theft, or manipulation of displayed information. Given the POS system context, such attacks could disrupt retail operations or lead to leakage of sensitive transaction or customer data.

For European organizations using the itsourcecode POS Point of Sale System version 1.0, this vulnerability poses a moderate risk. POS systems are critical infrastructure in retail and hospitality sectors, and exploitation could lead to unauthorized access to customer data, manipulation of transaction information, or disruption of sales operations. Although the vulnerability requires user interaction, attackers could craft phishing emails or malicious links to customers or employees to trigger the XSS payload. This could result in reputational damage, regulatory penalties under GDPR due to potential data breaches, and financial losses from operational disruptions. The medium severity score reflects limited direct system compromise but significant risk to data confidentiality and integrity. Organizations relying on this POS system should be vigilant, as attackers may leverage this vulnerability to escalate attacks or move laterally within networks. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate it, especially after public disclosure.

1. Immediate mitigation should include input validation and output encoding for the 'scripts' argument in the affected PHP file to prevent injection of malicious scripts. 2. If a patch from the vendor becomes available, prioritize its deployment across all affected POS systems. 3. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the POS web interface. 4. Conduct user awareness training to reduce the risk of social engineering attacks that could trigger the XSS payload. 5. Monitor web application logs for suspicious requests targeting the vulnerable endpoint. 6. Isolate POS systems from general corporate networks to limit lateral movement if exploitation occurs. 7. Employ web application firewalls (WAF) with rules to detect and block XSS attack patterns targeting the POS system. 8. Regularly review and update the POS system and related components to ensure all security patches are applied promptly.
