CVE-2006-6187 in Clickgallery
Summary
by MITRE
Multiple SQL injection vulnerabilities in ClickTech Click Gallery allow remote attackers to execute arbitrary SQL commands via the (1) currentpage or (2) gallery_id parameter to (a) view_gallery.asp, the (3) image_id parameter to (b) download_image.asp, the currentpage or (5) orderby parameter to (c) gallery.asp, or the currentpage parameter to (d) view_recent.asp.

The vulnerability described in CVE-2006-6187 represents a critical SQL injection flaw affecting ClickTech Click Gallery version 2.1. This vulnerability stems from inadequate input validation and sanitization within multiple web application scripts, creating multiple attack vectors that allow remote adversaries to execute arbitrary SQL commands. The affected components include view_gallery.asp, download_image.asp, gallery.asp, and view_recent.asp scripts, all of which process user-supplied parameters without proper sanitization measures. This weakness enables attackers to manipulate database queries through carefully crafted input strings that bypass normal validation procedures.
The technical implementation of this vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws where untrusted data is incorporated into SQL commands without proper escaping or parameterization. Attackers can exploit the vulnerability by manipulating the currentpage, gallery_id, image_id, and orderby parameters across different endpoints. The vulnerability manifests when user input is directly concatenated into SQL queries rather than being properly parameterized or escaped, allowing malicious SQL code to be executed within the database context. These parameters are processed in a manner that does not distinguish between legitimate user input and potentially harmful SQL commands, creating a direct pathway for database manipulation.
The operational impact of this vulnerability is severe and multifaceted, as it provides attackers with the capability to perform unauthorized database operations including data extraction, modification, or deletion. Remote attackers can potentially gain access to sensitive user information, manipulate gallery content, or even escalate privileges within the database system. The vulnerability affects the integrity and confidentiality of the web application's data layer, as it allows for arbitrary command execution at the database level. Additionally, the attack surface is expanded due to the presence of multiple vulnerable endpoints, increasing the probability of successful exploitation and providing attackers with multiple potential entry points.
Mitigation strategies for this vulnerability should focus on implementing proper input validation, parameterized queries, and output encoding techniques to prevent SQL injection attacks. Organizations should immediately apply patches or updates from ClickTech to address the identified vulnerabilities, while also implementing web application firewalls to monitor and filter suspicious SQL injection patterns. The implementation of proper input sanitization measures, including the use of prepared statements and parameterized queries, would effectively neutralize the exploitation vectors. Additionally, regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities in other application components, following industry best practices outlined in the OWASP Top Ten and NIST cybersecurity frameworks. The vulnerability also demonstrates the importance of proper application security testing and adheres to ATT&CK technique T1190 for exploiting vulnerabilities in web applications, highlighting the need for comprehensive security controls across all application layers.
