CVE-2006-6088 in i-Gallery
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in BlueCollar i-Gallery 3.4 allow remote attackers to inject arbitrary web script or HTML via the (1) n or (2) d parameter in igallery.asp, or (3) an unspecified parameter related to search, possibly the Search Gallery field, or the myquery parameter, in search.asp. NOTE: some of these details are obtained from third party information.

The vulnerability identified as CVE-2006-6088 represents a critical cross-site scripting flaw affecting BlueCollar i-Gallery version 3.4, a web-based image gallery management system. This vulnerability category falls under CWE-79 which specifically addresses cross-site scripting weaknesses in web applications. The flaw manifests through multiple attack vectors that collectively demonstrate the application's insufficient input validation and output encoding mechanisms. The vulnerability impacts both the main gallery interface and search functionality, creating a broad attack surface that malicious actors can exploit to inject malicious code into the application's response.
The technical implementation of this vulnerability stems from the application's failure to properly sanitize user-supplied input parameters before incorporating them into dynamic web page content. The attack occurs through three distinct parameter vectors: the 'n' and 'd' parameters within the igallery.asp file, and an unspecified search-related parameter that may involve the Search Gallery field or myquery parameter in search.asp. These parameters are directly reflected in the application's output without adequate HTML encoding or input validation, creating opportunities for attackers to execute arbitrary JavaScript code within the context of a victim's browser session. The vulnerability specifically affects the application's handling of user input that is subsequently rendered in web pages, making it a classic reflected XSS vulnerability.
From an operational impact perspective, this vulnerability poses significant risks to both end users and administrators of the affected i-Gallery system. Attackers can leverage these XSS flaws to steal session cookies, perform unauthorized actions on behalf of users, redirect victims to malicious sites, or even deface the gallery content. The reflected nature of the vulnerability means that attackers need only send a malicious link to victims, who would then execute the payload upon clicking the link. This makes the attack vector particularly dangerous in environments where users may be browsing the gallery and clicking on links from untrusted sources. The vulnerability also impacts the application's integrity and can potentially lead to privilege escalation if the gallery system allows administrative access through user sessions.
The security implications extend beyond simple script injection to encompass broader application security concerns that align with ATT&CK technique T1566 for phishing with social engineering and T1203 for exploitation for privilege escalation. Organizations using this vulnerable version of i-Gallery should implement immediate mitigations including input validation, output encoding, and proper parameter sanitization across all user-supplied inputs. The recommended approach involves implementing strict input validation that filters out potentially dangerous characters and implementing proper HTML encoding of all dynamic content before rendering. Additionally, organizations should consider implementing Content Security Policy headers and using secure coding practices to prevent similar vulnerabilities from occurring in other application components. The vulnerability highlights the critical importance of input validation and output encoding in web application security, particularly in systems that handle user-generated content or search functionality where user input is directly reflected in application responses.
