Multiple cross-site scripting (XSS) vulnerabilities in ASPilot Pilot Cart 7.3 allow remote attackers to inject arbitrary web script or HTML via the (1) countrycode parameter to contact.asp, USERNAME parameter to (2) gateway.asp and (3) cart.asp, and the specific parameter to (4) quote.asp and (5) buyitnow.
ASPilot Pilot Cart 7.3 suffers from multiple cross-site scripting (XSS) vulnerabilities, allowing attackers to inject malicious code into web pages viewed by users. Successful exploitation could lead to account compromise, data theft, or website defacement, severely impacting the confidentiality and integrity of the affected system.
Step 1: Payload Delivery: The attacker crafts a malicious URL containing a specially crafted payload within a vulnerable parameter (e.g., countrycode, USERNAME, specific).
Step 2: Request Submission: The attacker tricks a victim into clicking the malicious URL, or the attacker directly submits the URL to the vulnerable application.
Step 3: Server Processing: The ASPilot Pilot Cart 7.3 application receives the request and processes the parameters, including the malicious payload.
Step 4: Vulnerable Code Execution: The application fails to properly sanitize or encode the user-supplied input before rendering it in the HTML response.
Step 5: Payload Execution: The victim's web browser executes the injected JavaScript or HTML code, allowing the attacker to perform actions such as stealing cookies, redirecting the user, or defacing the website.
The vulnerability stems from insufficient input validation and output encoding within ASPilot Pilot Cart 7.3. Specifically, the application fails to properly sanitize user-supplied data before incorporating it into the HTML response. This allows attackers to inject malicious JavaScript or HTML code through various parameters, such as countrycode, USERNAME, and others. The lack of proper input validation and output encoding (e.g., HTML entity encoding) allows the injected code to execute within the context of the vulnerable website, leading to XSS.
While no specific APT groups are directly linked to this CVE, XSS vulnerabilities are commonly exploited by various threat actors for initial access and information gathering. This vulnerability could be used as part of a larger attack chain. Not on CISA KEV.
Web application firewall (WAF) logs showing suspicious HTTP requests containing JavaScript or HTML tags in parameter values.
Network traffic analysis revealing unusual HTTP requests with potentially malicious payloads in the URL parameters.
Server-side logs indicating unexpected behavior or errors related to parameter processing.
Security Information and Event Management (SIEM) alerts triggered by suspicious user activity or unusual web traffic patterns.
Implement robust input validation to sanitize all user-supplied data, ensuring that only expected data types and formats are accepted.
Apply output encoding (e.g., HTML entity encoding) to all user-supplied data before rendering it in the HTML response to prevent the execution of malicious scripts.
Update to the latest version of ASPilot Pilot Cart or apply vendor-provided patches.
Implement a web application firewall (WAF) to filter malicious requests and block XSS attempts.
Regularly scan the web application for vulnerabilities using automated tools.
Conduct security awareness training for users to educate them about the risks of clicking on suspicious links.
