CVE-2009-4669 in RoomPHPlanning
Summary
by MITRE
Multiple SQL injection vulnerabilities in RoomPHPlanning 1.6 allow remote attackers to execute arbitrary SQL commands via (1) the loginus parameter to Login.php or (2) the Old Password field to changepwd.php, and allow (3) remote authenticated administrators to execute arbitrary SQL commands via the id parameter to admin/userform.php.

The vulnerability identified as CVE-2009-4669 represents a critical security flaw in RoomPHPlanning version 1.6, a web-based room scheduling and planning application. This vulnerability manifests as multiple SQL injection opportunities that enable both unauthenticated and authenticated attackers to execute arbitrary SQL commands against the underlying database system. The flaw stems from inadequate input validation and sanitization within the application's authentication and administrative interfaces, creating pathways for malicious actors to manipulate database queries through carefully crafted inputs. The vulnerability affects three distinct entry points within the application's codebase, each presenting unique attack vectors that could lead to complete database compromise and potential system takeover.
The technical implementation of this vulnerability occurs through improper handling of user-supplied input in three separate PHP scripts. The first vector involves the loginus parameter in Login.php where unfiltered input directly influences SQL query construction, allowing attackers to bypass authentication mechanisms and gain unauthorized access to the system. The second vulnerability exists in the Old Password field of changepwd.php, where user-provided password data is concatenated into SQL statements without proper sanitization, enabling attackers to manipulate password change operations. The third and most severe vector targets authenticated administrators through the id parameter in admin/userform.php, where administrative users can be tricked into executing malicious SQL commands through manipulated identifiers. These vulnerabilities are classified under CWE-89, SQL Injection, which represents one of the most prevalent and dangerous web application security flaws in the industry. The attack patterns align with techniques documented in the MITRE ATT&CK framework under T1190 - Exploit Public-Facing Application, where adversaries target web applications to gain unauthorized access and execute arbitrary commands.
The operational impact of CVE-2009-4669 extends beyond simple data theft, as successful exploitation could lead to complete system compromise and unauthorized access to sensitive information. Attackers could extract all user credentials, administrative access details, room scheduling data, and potentially gain access to backend systems through database pivoting. The vulnerability's severity is amplified by the fact that it affects both anonymous attackers who can bypass authentication and authenticated administrators who may be tricked into executing malicious operations. Organizations using RoomPHPlanning 1.6 face significant risk of data breaches, system compromise, and potential regulatory violations if these vulnerabilities remain unpatched. The attack surface is particularly concerning as it affects core authentication and administrative functions, providing multiple pathways for exploitation and making the vulnerability difficult to detect and remediate. Database administrators and security teams must consider the implications of these vulnerabilities when assessing their overall security posture and implementing defense-in-depth strategies.
Mitigation strategies for CVE-2009-4669 require immediate implementation of input validation and parameterized queries throughout the affected application components. Organizations should prioritize patching or upgrading to versions of RoomPHPlanning that address these SQL injection vulnerabilities, as the vendor has likely released security updates to resolve these issues. The implementation of proper input sanitization and output encoding should be enforced across all user-facing parameters, with particular attention to authentication and administrative interfaces. Security measures should include the deployment of web application firewalls to detect and block suspicious SQL injection attempts, along with regular security assessments to identify similar vulnerabilities in other applications. Database access controls should be implemented to limit the privileges of application accounts, ensuring that even if injection attacks succeed, the damage remains contained. Additionally, organizations should conduct comprehensive security training for developers to prevent similar vulnerabilities in custom applications and establish robust code review processes that specifically address SQL injection prevention techniques. The remediation process should also include monitoring for exploitation attempts and implementing proper logging mechanisms to detect unauthorized access attempts that may indicate successful exploitation of these vulnerabilities.
