CVE-2025-58970 is a vulnerability classified as an improper neutralization of script-related HTML tags, commonly known as a basic Cross-Site Scripting (XSS) flaw, found in AmentoTech's Doctreat software up to version 1.6.7. This vulnerability allows an attacker to inject malicious scripts into web pages viewed by other users. The root cause is insufficient sanitization or encoding of user-supplied input before rendering it in the HTML context, enabling execution of arbitrary JavaScript code in the victim's browser. The CVSS 3.1 base score is 6.5, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be launched remotely over the network with low attack complexity, requires low privileges, and user interaction (such as clicking a crafted link). The vulnerability affects confidentiality, integrity, and availability, as malicious scripts can steal session tokens, manipulate page content, or perform actions on behalf of the user. The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component. No public exploits are currently known, but the vulnerability is published and should be addressed promptly. Doctreat is a platform often used for healthcare appointment booking and service management, making it a valuable target for attackers aiming to compromise sensitive user data or disrupt services.

For European organizations, particularly those in healthcare, medical services, or appointment management using Doctreat, this vulnerability poses risks including unauthorized access to user sessions, data leakage, and potential service disruption. Exploitation could lead to theft of personal health information (PHI), undermining patient privacy and violating GDPR regulations. The integrity of appointment data and communications could be compromised, affecting operational reliability and trust. Additionally, attackers could use the vulnerability to deliver malware or phishing payloads to users, amplifying the threat. Given the interconnected nature of healthcare IT systems in Europe, a successful attack could have cascading effects on partner organizations and service providers. The requirement for user interaction somewhat limits automated exploitation but does not eliminate risk, especially in phishing-prone environments.

Immediate mitigation should focus on applying official patches from AmentoTech once available. In the absence of patches, organizations should implement strict input validation and output encoding on all user-supplied data to neutralize script tags and other executable content. Employing a robust Content Security Policy (CSP) can help restrict the execution of unauthorized scripts. Web Application Firewalls (WAFs) configured to detect and block XSS payloads can provide an additional layer of defense. Security teams should conduct thorough code reviews and penetration testing to identify and remediate similar injection points. User awareness training to recognize phishing attempts that could trigger the vulnerability is also critical. Monitoring logs for suspicious activity related to script injection attempts can aid in early detection. Finally, segmenting critical systems and enforcing the principle of least privilege can limit the impact of any successful exploitation.
