CVE-2008-5892 in Click
Summary
by MITRE
Multiple SQL injection vulnerabilities in ClickAndEmail allow remote attackers to execute arbitrary SQL commands via (1) the ID parameter to admin_dblayers.asp in an update action, (2) the adminid parameter to admin_loginCheck.asp (aka the USERNAME field in admin_main.asp), and (3) the PassWord parameter to admin_loginCheck.asp (aka the PASSWORD field in admin_main.asp). NOTE: some of these details are obtained from third party information.

The CVE-2008-5892 vulnerability represents a critical security flaw in the ClickAndEmail application that exposes multiple SQL injection attack vectors through its administrative interfaces. This vulnerability classifies under CWE-89 which specifically addresses SQL injection weaknesses in software applications. The flaw enables remote attackers to execute arbitrary SQL commands against the underlying database system, potentially leading to complete system compromise and unauthorized data access. The vulnerability affects the administrative components of the application where user authentication and data management operations occur.
The technical implementation of this vulnerability occurs through three distinct parameter injection points within the application's administrative modules. The first attack vector targets the ID parameter in admin_dblayers.asp during update operations, allowing attackers to manipulate database queries through crafted input values. The second vector exploits the adminid parameter in admin_loginCheck.asp, which corresponds to the USERNAME field in admin_main.asp, enabling attackers to inject malicious SQL code during authentication processes. The third and final vector targets the PassWord parameter in admin_loginCheck.asp, corresponding to the PASSWORD field in admin_main.asp, which allows SQL injection during credential validation. These injection points represent classic SQL injection vulnerabilities where user-supplied input is directly incorporated into database queries without proper sanitization or parameterization.
The operational impact of CVE-2008-5892 extends far beyond simple data theft, as successful exploitation can provide attackers with complete administrative control over the affected system. Attackers can leverage these vulnerabilities to extract sensitive information including user credentials, database schemas, and confidential business data. The implications include potential data breaches, unauthorized system modifications, and complete compromise of the administrative interface. According to ATT&CK framework, this vulnerability maps to T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) as attackers may use these vulnerabilities to establish persistent access and exfiltrate data through various network protocols. The vulnerability's remote nature makes it particularly dangerous as it requires no local access or physical presence to exploit, and can be automated through various attack frameworks.
Mitigation strategies for CVE-2008-5892 must focus on implementing proper input validation and parameterized queries throughout the application code. The most effective defense involves replacing direct string concatenation in SQL queries with prepared statements or parameterized queries that separate SQL command structure from data input. Organizations should implement comprehensive input sanitization routines that filter or escape special characters that could be used in SQL injection attacks. Additionally, the principle of least privilege should be enforced by limiting database permissions for the application's database accounts, ensuring they only have access to necessary tables and operations. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other application components, as SQL injection remains one of the most prevalent and dangerous web application vulnerabilities. The vulnerability also highlights the importance of maintaining updated security patches and following secure coding practices that prevent injection flaws from occurring in the first place.
