Document Title: =============== uDoctorAppointment v2.1.1 - Multiple XSS Vulnerabilities References (Source): ==================== https://www.vulnerability-lab.com/get_content.php?id=2288 Release Date: ============= 2021-12-15 Vulnerability Laboratory ID (VL-ID): ==================================== 2288 Common Vulnerability Scoring System: ==================================== 5 Vulnerability Class: ==================== Cross Site Scripting - Non Persistent Current Estimated Price: ======================== 500€ - 1.000€ Product & Service Introduction: =============================== Clinic management, doctor or therapist online medical appointment scheduling system for the management of health care. uDoctorAppointment script allows doctors to register and appropriate membership plan with different features. Patients can view doctor profiles before booking appointments. The site administrator or doctor may create and manage advanced schedules, create working time slots for each day of the week, define time off etc. (Copy of the Homepage:https://www.apphp.com/codemarket/items/1/udoctorappointment-php-script ) Abstract Advisory Information: ============================== The vulnerability laboratory core research team discovered multiple non-persistent cross site web vulnerabilities in the uDoctorAppointment script web-application. Affected Product(s): ==================== ApPHP Product: uDoctorAppointment v2.1.1 - Health Care Script (PHP) (Web-Application) Product: ApPHP MVC Framework v1.1.5 (Framework) Vulnerability Disclosure Timeline: ================================== 2021-09-01: Researcher Notification & Coordination (Security Researcher) 2021-09-02: Vendor Notification (Security Department) 2021-09-10: Vendor Response/Feedback (Security Department) 2021-**-**: Vendor Fix/Patch (Service Developer Team) 2021-**-**: Security Acknowledgements (Security Department) 2021-12-15: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== Medium Authentication Type: ==================== Pre Auth (No Privileges or Session) User Interaction: ================= Low User Interaction Disclosure Type: ================ Responsible Disclosure Technical Details & Description: ================================ Multiple non-persistent cross site vulnerabilities has been discovered in the official uDoctorAppointment v2.1.1 script web-application. The vulnerability allows remote attackers to inject own malicious script codes with non-persistent attack vector to compromise browser to web-application requests from the client-side. The cross site security web vulnerabilities are located in the `created_at`, `created_date` and `sent_at` parameters of the `filter` web module. The injection point is located in the parameters and the execution occurs in the filter module. The request method to inject the malicious script code is GET and the attack vector of the vulnerability is non-persistent on client-side. Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing attacks, non-persistent external redirects to malicious source and non-persistent manipulation of affected application modules. Request Method(s): [+] GET Vulnerable Module(s): [+] ./doctorReviews/doctorReviews [+] ./orders/orders [+] /mailingLog/manage [+] /orders/doctorsManage [+] /news/manage [+] /newsSubscribers/manage [+] /doctorReviews/manage/status/approved [+] /appointments/manage Vulnerable Parameter(s): [+] created_at [+] created_date [+] sent_at [+] appointment_date Affected Module(s): [+] Filter Proof of Concept (PoC): ======================= The client-side cross site scripting web vulnerabilities can be exploited by remote attackers without account and with low user interaction.

Disallow the usage of special chars in the affected parameters on get method requests. Sansitize the vulnerable output location to resolve the point of execution in the filter module.
