Overview
CVE-2025-35029 describes a stored cross-site scripting (XSS) vulnerability discovered in Medical Informatics Engineering’s Enterprise Health software. This vulnerability allows an authenticated attacker to inject malicious JavaScript code into the ‘Demographic Information’ page of the application. When a user views the affected page, the injected script will execute, potentially leading to data theft, session hijacking, or other malicious activities.
The vulnerability was patched on March 14, 2025. It is critical for organizations using affected versions of Enterprise Health to apply the available update as soon as possible.
Technical Details
The vulnerability stems from insufficient input sanitization on the ‘Demographic Information’ page. Specifically, the application fails to properly encode or escape user-supplied data before storing it in the database. An attacker can exploit this by injecting malicious JavaScript code within a demographic field, such as the patient’s name or address. This injected code is then stored in the database.
When a user accesses the ‘Demographic Information’ page containing the injected payload, the application retrieves the unsanitized data from the database and renders it in the user’s browser. Because the injected data contains JavaScript code, the browser executes it within the context of the Enterprise Health application.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-35029 a score of 3.5, indicating a LOW severity. The CVSS vector is likely to be something similar to AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N (Network, Low complexity, Low privileges, Requires user interaction, Unchanged scope, No confidentiality impact, Low integrity impact, No availability impact). While the score is low, the potential impact on healthcare data necessitates prompt remediation.
The relatively low score is primarily due to the requirement for an attacker to be authenticated and the need for user interaction (the victim must view the affected page). However, within a healthcare environment, the potential for widespread access and trusted user base increases the risk.
Possible Impact
Successful exploitation of this vulnerability could have the following consequences:
- Data Theft: The injected JavaScript could be used to steal sensitive patient data, such as medical history, personal information, and insurance details.
- Session Hijacking: An attacker could hijack a user’s session, gaining unauthorized access to their account and privileges within the Enterprise Health system.
- Defacement: The attacker could modify the appearance of the ‘Demographic Information’ page or other parts of the application.
- Malware Distribution: The injected script could be used to redirect users to malicious websites or download malware onto their systems.
Mitigation and Patch Steps
- Apply the Patch: Upgrade Medical Informatics Engineering Enterprise Health to version released after 2025-03-14 which includes the fix for this vulnerability. Contact Medical Informatics Engineering support for the specific patched version.
- Input Sanitization: Implement robust input validation and sanitization techniques to prevent the injection of malicious code. All user-supplied data should be properly encoded or escaped before being stored in the database.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block XSS attacks. Configure the WAF with rules specifically designed to prevent XSS vulnerabilities.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities.
- User Awareness Training: Educate users about the risks of XSS attacks and how to identify suspicious activity.
