This cross-site scripting vulnerability exists in the auction.pl script of MakeBid Auction Deluxe version 3.30, representing a critical security flaw that allows remote attackers to inject malicious scripts into web forms. The vulnerability specifically affects multiple form fields including TITLE, DESCTIT, DESC, searchstring, ALIAS, EMAIL, ADDRESS1 through ADDRESS3, PHONE1 through PHONE3, and other user input fields. The flaw stems from inadequate input validation and output encoding mechanisms within the auction script, which fails to properly sanitize user-supplied data before processing or displaying it back to other users.
The technical implementation of this vulnerability follows a classic XSS pattern where malicious input is accepted without proper sanitization and subsequently rendered in web pages viewed by other users. When users submit data through these vulnerable fields, the application does not adequately escape special characters or validate input against known malicious patterns. This creates an environment where attackers can inject JavaScript code or other malicious payloads that execute in the context of other users' browsers. The attack vector operates through web forms where user input is directly incorporated into HTML output without proper encoding, making it susceptible to script injection attacks.
The operational impact of this vulnerability is significant as it enables attackers to access sensitive user information and potentially escalate privileges within the application context. Attackers can craft malicious payloads that steal session cookies, redirect users to phishing sites, or execute arbitrary code in the victim's browser. The vulnerability affects multiple data fields, increasing the attack surface and providing numerous entry points for exploitation. Since the application handles user registration and auction data, successful exploitation could lead to unauthorized access to user accounts, data theft, and potential account takeovers. The vulnerability affects the core functionality of the auction platform, making it a critical concern for any organization using this software.
Mitigation strategies should focus on implementing comprehensive input validation and output encoding mechanisms across all user-facing form fields. The primary defense involves sanitizing all user input by escaping special HTML characters and implementing proper content security policies. Organizations should deploy web application firewalls to detect and block malicious payloads, while also implementing strict input validation that rejects suspicious patterns and characters. The solution aligns with CWE-79 which categorizes cross-site scripting vulnerabilities and follows ATT&CK technique T1059.007 for script injection. Regular security updates and patches should be applied to the MakeBid Auction Deluxe software, while developers should implement proper HTML escaping routines and input sanitization functions. Additionally, implementing proper access controls and monitoring user activities can help detect potential exploitation attempts. Organizations should also consider deploying CSP headers to prevent script execution and establish security awareness training for users to recognize potential phishing attempts that may exploit this vulnerability.
