The vulnerability identified as CVE-2003-0585 represents a critical SQL injection flaw within the Brooky eStore web application version 1.0.1 through 1.0.2b. This security weakness specifically affects the login.asp component which processes user authentication requests. The vulnerability stems from inadequate input validation and sanitization mechanisms within the application's database interaction code, creating an exploitable condition that allows malicious actors to manipulate the underlying SQL queries executed by the system. The flaw manifests when the application fails to properly escape or filter user-supplied input data before incorporating it into SQL command structures, directly violating fundamental security principles of input validation and database query construction.
The technical implementation of this vulnerability occurs through the manipulation of two specific parameters within the login.asp script: the user and pass parameters. When an attacker submits malicious input through these fields, the application incorporates the unvalidated data directly into SQL queries without proper sanitization. This allows threat actors to inject additional SQL commands that can manipulate the database query execution flow. The vulnerability aligns with CWE-89 which categorizes SQL injection as a direct result of insufficient input validation and improper SQL query construction. Attackers can leverage this weakness to bypass authentication mechanisms entirely, potentially gaining unauthorized access to user accounts, administrative privileges, or sensitive database information. The attack vector is particularly dangerous as it requires no prior authentication and can be executed remotely through standard web browser interactions.
The operational impact of this vulnerability extends far beyond simple authentication bypass. Successful exploitation can enable attackers to execute arbitrary SQL commands on the affected database server, potentially leading to complete system compromise. Threat actors can extract sensitive user credentials, personal information, financial data, and other confidential database contents. The vulnerability also provides opportunities for data manipulation, deletion, or corruption, creating significant business continuity risks. From an attacker perspective, this vulnerability maps to multiple ATT&CK techniques including T1190 for exploitation of vulnerabilities, T1078 for valid accounts usage, and T1046 for remote service attacks. Organizations running affected versions of Brooky eStore face substantial risk of unauthorized access, data breaches, and potential regulatory compliance violations that could result in significant financial and reputational damage.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The primary solution involves implementing proper input validation and parameterized queries throughout the application codebase to prevent SQL injection attacks. Organizations should upgrade to patched versions of Brooky eStore or implement comprehensive code modifications that sanitize all user inputs before database interaction. Additional protective measures include implementing web application firewalls, establishing proper database user permissions, and deploying intrusion detection systems to monitor for suspicious SQL query patterns. Security teams should also conduct thorough code reviews and penetration testing to identify similar vulnerabilities in other application components. The remediation process should follow established security frameworks such as OWASP Top Ten and NIST guidelines for secure coding practices, ensuring that input validation mechanisms are robust and comprehensive across all database interaction points.
