The vulnerability identified as CVE-2006-0108 represents a critical SQL injection flaw within the Timecan CMS content management system, specifically affecting the mcl_login.asp component. This vulnerability arises from inadequate input validation mechanisms that fail to properly sanitize user-supplied data before incorporating it into database queries. The flaw manifests when the email parameter is processed during the login authentication sequence, creating an exploitable entry point for malicious actors seeking unauthorized system access. The vulnerability's classification aligns with CWE-89, which specifically addresses SQL injection vulnerabilities where untrusted data is directly concatenated into SQL commands without proper sanitization or parameterization.
The technical exploitation of this vulnerability occurs when remote attackers submit specially crafted email addresses containing malicious SQL payload sequences to the mcl_login.asp script. These payloads can manipulate the underlying database query structure, potentially allowing attackers to execute arbitrary SQL commands with the privileges of the database user account used by the CMS. The attack vector is particularly dangerous because it targets the authentication mechanism, which could enable attackers to bypass login controls entirely, access administrative functions, or extract sensitive database information including user credentials, personal data, and system configuration details.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it provides attackers with the capability to perform data manipulation, information disclosure, and potentially system compromise. Attackers could leverage this vulnerability to escalate privileges, modify or delete database records, create new administrative accounts, or even execute system commands if the database user has sufficient permissions. The vulnerability affects the integrity and confidentiality of the Timecan CMS installation, potentially exposing sensitive user information and undermining the security posture of organizations relying on this platform for content management. The risk is amplified by the fact that authentication bypass capabilities could allow attackers to gain persistent access to the system.
Mitigation strategies for CVE-2006-0108 should prioritize immediate implementation of proper input validation and parameterized queries within the mcl_login.asp component. Organizations should ensure that all user inputs are properly sanitized and validated before being processed in database operations, implementing strict input filtering mechanisms that reject or escape potentially malicious characters. The recommended approach aligns with ATT&CK technique T1190, which focuses on exploiting vulnerabilities in applications to gain access to systems. Security patches should be applied immediately if available, or alternatively, organizations should implement web application firewalls and input validation rules to block known malicious patterns. Additionally, database access should be restricted to minimum required privileges, and all database interactions should utilize parameterized queries or stored procedures to prevent SQL injection exploitation. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other components of the CMS and prevent analogous attacks from compromising system integrity.
