CVE-2008-6675 in QuickerSite
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in QuickerSite 1.8.5 allow remote attackers to inject arbitrary web script or HTML via (1) the close parameter to showThumb.aspx; (2) SB_redirect and (3) SB_feedback parameters in process_send.asp, as reachable through default.asp; (4) paramCode and (5) cColor parameters to picker.asp; and the (6) query string, (7) Referer header, and (8) X-FORWARDED-FOR header to rss.asp.

The vulnerability CVE-2008-6675 represents a critical cross-site scripting flaw in QuickerSite version 1.8.5 that exposes multiple entry points for remote attackers to inject malicious web scripts and HTML content. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, which is classified as a fundamental web application security weakness that allows attackers to execute scripts in the context of other users. The flaw affects several key components of the QuickerSite application, creating a wide attack surface that could potentially compromise user sessions and data integrity.
The technical implementation of this vulnerability spans across multiple ASP pages within the QuickerSite application, each presenting distinct attack vectors for XSS exploitation. The showThumb.aspx page accepts a close parameter that can be manipulated to inject malicious scripts, while process_send.asp contains three vulnerable parameters including SB_redirect and SB_feedback that can be exploited through default.asp. Additionally, picker.asp presents two more attack vectors through paramCode and cColor parameters, while rss.asp demonstrates the breadth of this vulnerability by accepting malicious input through query string parameters, Referer header, and X-FORWARDED-FOR header. These multiple entry points significantly increase the probability of successful exploitation and demonstrate poor input validation practices throughout the application's codebase.
The operational impact of this vulnerability extends beyond simple script injection, as it provides attackers with the capability to hijack user sessions, steal sensitive information, manipulate application data, and potentially establish persistent backdoors. The attack surface encompasses both reflected and stored XSS scenarios, with some parameters allowing attackers to inject scripts that execute immediately upon page load while others may store malicious content for future victims. This vulnerability aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments and T1566.002 for spearphishing links, as attackers could craft malicious URLs that, when clicked by unsuspecting users, would execute the injected scripts. The widespread nature of these vulnerabilities suggests a systemic lack of proper input sanitization and output encoding throughout the application architecture.
Mitigation strategies for CVE-2008-6675 should focus on implementing comprehensive input validation and output encoding across all affected pages. The most effective approach involves sanitizing all user-supplied input through proper encoding mechanisms such as HTML entity encoding for output rendering, implementing strict input validation with allowlists, and employing Content Security Policy (CSP) headers to prevent script execution. Organizations should also consider implementing proper parameter validation for all HTTP request parameters, including headers, and establish secure coding practices that prevent direct user input from being rendered without proper sanitization. Additionally, regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other application components, as this vulnerability demonstrates a pattern of insufficient input validation that could exist in other parts of the application. The remediation process should include updating to a patched version of QuickerSite, implementing web application firewalls, and establishing monitoring mechanisms to detect potential exploitation attempts.
