CVE-2026-112092 in online-clinic-management-system
Summary
by MITRE • 10/19/2026
A flaw has been found in subhajitkhan online-clinic-management-system up to e9ee77a8827a1446220fa07ee693dc4d9a29a578. The affected element is the function echo of the file doctorregistration.php of the component Doctor Registration. Executing a manipulation of the argument doc_name can lead to cross site scripting. It is possible to launch the attack remotely. The exploit has been published and may be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.

Analysis

The vulnerability identified in subhajitkhan online-clinic-management-system represents a significant security risk within the Doctor Registration component, specifically targeting the doctorregistration.php file. This flaw is rooted in improper neutralization of input during web page generation, which allows for cross-site scripting attacks. The core technical issue lies in how the application handles user-supplied data passed through the doc_name argument when it is processed by the echo function. Instead of properly sanitizing or encoding this input before rendering it into the HTML output, the system directly outputs untrusted data. This failure to validate and escape special characters creates an injection point where malicious scripts can be embedded within legitimate web pages viewed by other users.
From a technical perspective, this is classified as CWE-79: Improper Neutralization of Input During Web Page Generation, commonly known as Cross-Site Scripting (XSS). The vulnerability enables remote attackers to execute arbitrary script code in the context of the affected website's domain. Because the exploit has been published and is available for use, the threat landscape is actively hostile. Attackers can craft malicious links or forms that, when accessed by a victim with valid credentials or even just visiting a compromised page, will trigger the execution of injected JavaScript. This code runs under the same origin policy as the application, granting it access to cookies, session tokens, and other sensitive information stored in the browser for that domain.
The operational impact of this vulnerability is severe due to its remote exploitability. An attacker does not need physical proximity or local system access; they can launch attacks over a network from any location with internet connectivity. Successful exploitation could lead to account hijacking if session cookies are stolen, allowing unauthorized access to the doctor's portal and patient records. Furthermore, attackers might use this vector for phishing by redirecting users to malicious sites that mimic the clinic management interface, thereby harvesting credentials or distributing malware. The lack of version-specific details complicates patch identification because the project utilizes a rolling release model with continuous delivery. This means there are no discrete version numbers to reference in security advisories, making it difficult for administrators to determine exactly which build contains the fix without monitoring commit history directly against the specified hash e9ee77a8827a1446220fa07ee693dc4d9a29a578.
Mitigation strategies must focus on both immediate defensive measures and long-term remediation. Since the project has not yet responded to early issue reports, administrators should implement input validation at the application layer if source code access is available. This involves ensuring that all user inputs are strictly validated against expected formats and encoded before being rendered in HTML output using context-appropriate encoding such as HTML entity encoding for XSS prevention. Additionally, deploying a Web Application Firewall can provide an additional layer of defense by filtering out malicious payloads associated with known XSS patterns. For users unable to modify the source code immediately, restricting access to the doctor registration module through network-level controls or strong authentication mechanisms may reduce exposure until the vendor provides a patched release.
This incident highlights critical gaps in secure development practices and vulnerability management processes within the project. The absence of versioned releases complicates standard patching workflows typically aligned with CVE tracking systems. Security teams should monitor official repositories for commits that address input handling in doctorregistration.php rather than relying on traditional version updates. Engaging directly with the maintainers to urge a response is also advisable, as delayed remediation increases the window of exposure for all users of this online clinic management system. Adhering to OWASP Top 10 guidelines regarding injection flaws and implementing robust input sanitization protocols are essential steps toward securing such web applications against similar threats in the future.
