PHPJabbers Night Club Booking Software has stored XSS in the name parameter in the reservations tab.
PHPJabbers Night Club Booking Software is vulnerable to Cross-Site Scripting (XSS), allowing attackers to inject malicious scripts into the application. This vulnerability, stemming from improper input validation in the reservations tab's name parameter, could lead to session hijacking, data theft, and website defacement. Successful exploitation requires no authentication and can impact any user interacting with the compromised application.
Step 1: Payload Delivery: The attacker crafts a malicious payload, typically a JavaScript snippet, designed to execute within the victim's browser. This payload is embedded within the 'name' field when creating a new reservation or modifying an existing one. Step 2: Payload Injection: The attacker submits the malicious payload through the application's reservation form, placing the XSS payload in the 'name' field. Step 3: Data Storage: The vulnerable application stores the attacker's malicious payload in its database, associated with the reservation. Step 4: Victim Interaction: A legitimate user, such as an administrator or another customer, views the reservations tab within the application. Step 5: Payload Execution: The application retrieves the reservation data, including the attacker's malicious payload from the database, and displays it on the reservations tab. Because the 'name' field is not properly sanitized or encoded, the browser interprets the attacker's JavaScript payload as executable code. Step 6: Attack Execution: The attacker's JavaScript payload executes within the victim's browser, enabling various malicious actions, such as stealing cookies, redirecting the user, or defacing the website.
The vulnerability lies in the lack of proper input sanitization and output encoding of the 'name' parameter within the reservations functionality of PHPJabbers Night Club Booking Software. Specifically, the application fails to adequately filter or encode user-supplied input before displaying it on the reservations tab. This allows an attacker to inject malicious JavaScript code into the 'name' field. When a user views the reservations tab, the injected JavaScript executes within the context of the user's browser, enabling a variety of attacks, including stealing cookies, redirecting users to phishing sites, or defacing the website. The root cause is a missing or inadequate implementation of input validation and output encoding (e.g., HTML entity encoding) to prevent the interpretation of user-supplied data as executable code.
While no specific APT groups are directly linked to this CVE, the ease of exploitation makes it attractive to a wide range of attackers, including script kiddies and opportunistic attackers. The impact of successful exploitation (e.g., session hijacking, defacement) could be used as a precursor to more sophisticated attacks. CISA KEV: Not listed.
Web Application Firewall (WAF) logs showing suspicious HTTP requests containing JavaScript payloads (e.g., <script>, onerror, javascript:).
Network traffic analysis revealing unusual HTTP requests with malicious payloads in the 'name' parameter of reservation requests.
Server-side logs indicating the injection of malicious scripts into the database.
Browser-side monitoring for unexpected JavaScript execution or redirects.
Security Information and Event Management (SIEM) systems configured to detect XSS attempts based on signature matching or behavioral analysis.
Implement robust input validation to filter out or sanitize potentially malicious characters and patterns in the 'name' parameter. This should be performed on the server-side.
Implement output encoding (e.g., HTML entity encoding) to ensure that user-supplied data is treated as data and not as executable code when displayed on the reservations tab.
Use a Content Security Policy (CSP) to restrict the sources from which the browser can load resources, mitigating the impact of successful XSS attacks.
Regularly update the PHPJabbers Night Club Booking Software to the latest version, which may include patches for this and other vulnerabilities.
Conduct thorough security audits and penetration testing to identify and address any remaining vulnerabilities.
Implement a Web Application Firewall (WAF) to filter malicious requests before they reach the application.
