CVE-2005-4227 in DCP-Portal
Summary
by MITRE
Multiple "potential" SQL injection vulnerabilities in DCP-Portal 6.1.1 might allow remote attackers to execute arbitrary SQL commands via (1) the password and username parameters in advertiser.php, (2) the aid parameter in announcement.php, (3) the dcp5_member_id, year, agid, day, day_s, hour, minute, month, month_s, and year_s parameters in calendar.php, (4) the cid parameter in contents.php, (5) the dcp5_member_id parameter in forums.php, (6) the bid parameter in go.php, (7) the lid parameter in golink.php, (8) the dcp5_member_id and mid parameters in inbox.php, (9) the catid, dcat, and dl parameters in index.php, (10) the dcp5_member_id in informer.php, (11) the nid parameter in news.php, (12) the type and rate parameters in rate.php, (13) the q parameter in search.php, and (14) the dcp5_member_id in update.php. NOTE: other vectors in the PHP-CHECKER report are also covered by CVE-2005-3365 and CVE-2005-0454.

The vulnerability identified in DCP-Portal 6.1.1 represents a critical SQL injection flaw that affects multiple script files across the application's functionality. This issue stems from inadequate input validation and sanitization mechanisms that fail to properly escape or filter user-supplied data before incorporating it into database queries. The vulnerability is classified under CWE-89 which specifically addresses SQL injection vulnerabilities where untrusted data is directly concatenated into SQL command strings without proper escaping or parameterization. The affected parameters span across various modules including authentication, calendar management, content handling, forum operations, and user messaging systems, indicating a systemic flaw in the application's data handling architecture.
Multiple attack vectors exist within the vulnerable DCP-Portal application, each presenting distinct opportunities for malicious actors to exploit the SQL injection vulnerability. The username and password parameters in advertiser.php provide direct access points for credential manipulation, while the aid parameter in announcement.php allows attackers to manipulate announcement records. Calendar.php contains numerous parameters including dcp5_member_id, year, agid, day, day_s, hour, minute, month, month_s, and year_s that collectively enable attackers to manipulate calendar entries and potentially access restricted calendar data. The cid parameter in contents.php, bid parameter in go.php, and lid parameter in golink.php represent additional pathways for data manipulation and information disclosure. Other affected modules include forums.php with dcp5_member_id parameter, inbox.php with dcp5_member_id and mid parameters, index.php with catid, dcat, and dl parameters, informer.php with dcp5_member_id parameter, news.php with nid parameter, rate.php with type and rate parameters, search.php with q parameter, and update.php with dcp5_member_id parameter.
The operational impact of this vulnerability extends beyond simple data theft and encompasses full database compromise capabilities. Remote attackers can execute arbitrary SQL commands, potentially gaining unauthorized access to sensitive user information, modifying database records, creating new user accounts, or even escalating privileges within the database system. The vulnerability's widespread nature across multiple files suggests that attackers could systematically target different application modules to achieve comprehensive system compromise. This type of vulnerability aligns with ATT&CK technique T1071.005 which covers application layer protocol manipulation, and T1046 which describes network service scanning that could reveal vulnerable endpoints. The attack surface is particularly concerning given that many of these parameters are likely exposed through web forms, URL parameters, or API endpoints that are publicly accessible.
The exploitation of these SQL injection vulnerabilities follows standard attack patterns where malicious input is crafted to manipulate the SQL query execution flow. Attackers typically construct payloads that can either extract data through error-based or union-based SQL injection techniques, or directly execute commands through blind SQL injection methods. The vulnerability's classification under multiple CVE identifiers including CVE-2005-3365 and CVE-2005-0454 indicates that similar vulnerabilities exist in related software components, suggesting a broader pattern of insecure coding practices. Organizations should implement comprehensive input validation, parameterized queries, and proper output encoding as mitigation strategies. The vulnerability directly violates security best practices outlined in OWASP Top 10 2017 category A03: Injection, which emphasizes the importance of proper input validation and output encoding to prevent injection attacks. Additionally, the vulnerability demonstrates the importance of Principle of Least Privilege implementation where database connections should operate with minimal required permissions to limit potential damage from successful injection attacks.
