CVE-2025-7148 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of the CodeAstro Simple Hospital Management System, specifically affecting the /patient.html component's POST parameter handler. This vulnerability arises from insufficient input validation or sanitization of user-supplied data in one or more POST parameters, allowing an attacker to inject malicious scripts that execute in the context of the victim's browser. The vulnerability is remotely exploitable without requiring authentication, although it does require some user interaction (e.g., a victim clicking a crafted link or submitting a form). The CVSS 4.0 base score is 5.1, indicating a medium severity level. The attack vector is network-based with low attack complexity, no privileges required, and no user authentication needed, but user interaction is necessary. The impact primarily affects confidentiality and integrity at a low level, with no direct impact on availability or system control. Exploitation could lead to session hijacking, theft of sensitive patient data, or unauthorized actions performed on behalf of the victim user within the hospital management system interface. Multiple parameters may be vulnerable, increasing the attack surface. No patches or fixes have been published yet, and no known exploits are currently observed in the wild, but public disclosure of the exploit code increases the risk of exploitation attempts.

For European healthcare organizations using CodeAstro Simple Hospital Management System 1.0, this XSS vulnerability poses a significant risk to patient data confidentiality and system integrity. Exploitation could enable attackers to steal session tokens, impersonate legitimate users, or inject malicious content that compromises user trust and system reliability. Given the sensitive nature of healthcare data protected under GDPR, any breach could lead to severe regulatory penalties and reputational damage. Additionally, compromised hospital management systems could disrupt patient care workflows, indirectly affecting availability and patient safety. The medium severity rating suggests a moderate risk, but the healthcare context elevates the potential impact. European hospitals and clinics relying on this software should consider the threat seriously, especially since the vulnerability is remotely exploitable and publicly disclosed, increasing the likelihood of targeted attacks.

Organizations should immediately audit their deployment of CodeAstro Simple Hospital Management System to identify affected versions. In absence of an official patch, implement web application firewall (WAF) rules to detect and block malicious payloads targeting the /patient.html POST parameters. Employ strict input validation and output encoding on all user inputs, especially POST parameters, to prevent script injection. Conduct thorough security testing, including automated scanning and manual code review, focusing on input handling in the patient management modules. Educate users about phishing and social engineering risks to reduce successful exploitation via user interaction. Monitor logs for unusual activities related to patient.html requests. Plan for an urgent update or migration to a patched version once available. Additionally, isolate the hospital management system within a segmented network zone with restricted access to minimize lateral movement if exploitation occurs.
