The vulnerability identified as CVE-2005-1561 represents a critical cross-site scripting flaw affecting MaxWebPortal versions 1.3.5 and earlier. This vulnerability resides within the post.asp script which serves as a core component for handling user posts and forum interactions. The flaw manifests through three specific parameters named mod, M, and type which are processed without adequate input validation or output encoding, creating an avenue for malicious actors to inject arbitrary web scripts or HTML content into the application's response.
The technical nature of this vulnerability aligns with CWE-79, which specifically addresses Cross-Site Scripting vulnerabilities in web applications. This classification indicates that the application fails to properly sanitize user-supplied input before incorporating it into dynamically generated web pages. The vulnerability operates by accepting unfiltered parameters from HTTP requests and directly embedding them into the HTML response without proper sanitization or encoding mechanisms. Attackers can exploit this by crafting malicious payloads containing script tags or other HTML elements that will execute in the context of other users' browsers when they view the affected pages.
The operational impact of this vulnerability is significant as it allows remote attackers to execute arbitrary scripts in the browser context of victims who access the compromised portal. This can lead to session hijacking, credential theft, defacement of the portal content, or redirection to malicious websites. The attack requires no special privileges or authentication, making it particularly dangerous as it can be exploited by anyone who can submit requests to the vulnerable application. The affected parameters mod, M, and type suggest this vulnerability impacts various portal functionalities including module selection, main navigation, and content type specifications, potentially affecting multiple user-facing interfaces.
The exploitation of this vulnerability demonstrates a fundamental flaw in the application's security architecture where input validation occurs too late in the processing cycle or not at all. According to ATT&CK framework category T1190, this represents a web application attack vector that leverages insecure input handling to achieve unauthorized code execution. The vulnerability also reflects poor secure coding practices that fail to implement proper output encoding or sanitization techniques. Organizations using MaxWebPortal versions prior to 1.3.6 should immediately implement mitigations including input validation, output encoding, and parameter sanitization. The most effective remediation involves implementing strict input validation for all user-supplied parameters and ensuring proper HTML encoding of dynamic content before rendering. Additionally, implementing a Content Security Policy can provide an additional layer of protection against script injection attacks.
