The vulnerability identified as CVE-2006-7025 represents a critical sql injection flaw within the Bookmark4U web application version 2.0 and 2.1. This vulnerability exists in the administrative configuration file admin/config.php where the sqlcmd parameter is processed without adequate input validation or sanitization. The flaw allows remote attackers to execute arbitrary sql commands against the underlying database system, potentially leading to complete system compromise and data exfiltration.
This vulnerability maps directly to CWE-89 which defines sql injection as the insertion of malicious sql code into input fields for execution by the database. The specific technical flaw occurs when user-supplied data from the sqlcmd parameter is directly incorporated into sql queries without proper parameterization or escaping mechanisms. The absence of input sanitization creates an exploitable condition where attackers can manipulate the sql query structure to perform unauthorized database operations.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete system compromise. An attacker could leverage this vulnerability to extract sensitive information including user credentials, database schema details, and potentially gain administrative access to the web application. The remote nature of the attack means that exploitation does not require physical access to the system, making it particularly dangerous for web applications hosting sensitive data. This vulnerability also enables attackers to perform destructive operations such as data modification, deletion, or even database corruption.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and parameterized queries. The most effective approach involves using prepared statements with parameterized sql queries to ensure that user input is treated as data rather than executable code. Additionally, implementing proper input sanitization routines and employing web application firewalls can provide additional layers of protection. The principle of least privilege should also be enforced where database accounts used by the web application have minimal required permissions, preventing attackers from escalating privileges even if successful exploitation occurs. This vulnerability demonstrates the critical importance of input validation in web applications and aligns with the attack pattern described in the mitre att&ck framework under the database access and data exfiltration categories.
