Summary
by MITRE
Multiple SQL injection vulnerabilities in phpMyRealty (PMR) 1.0.9 allow (1) remote attackers to execute arbitrary SQL commands via the type parameter to search.php and (2) remote authenticated administrators to execute arbitrary SQL commands via the listing_updated_days parameter to admin/findlistings.php. NOTE: some of these details are obtained from third party information.

The vulnerability CVE-2007-6472 represents a critical security flaw in phpMyRealty version 1.0.9, a web-based real estate management system that was widely deployed in the mid-2000s. This vulnerability manifests as multiple SQL injection flaws that can be exploited by attackers to gain unauthorized access to the underlying database system, potentially leading to complete system compromise and data exfiltration. The vulnerability affects the core functionality of the application by failing to properly sanitize user input before incorporating it into SQL queries, creating an avenue for malicious actors to manipulate database operations through crafted input parameters.
The technical implementation of this vulnerability occurs through two distinct attack vectors within the application's codebase. The first vector targets the type parameter in the search.php file, which allows remote attackers to inject malicious SQL commands without requiring authentication. This represents a classic SQL injection vulnerability where user-supplied input directly influences the execution of database queries. The second vector involves the listing_updated_days parameter in admin/findlistings.php, which requires authenticated administrator access but still permits arbitrary SQL command execution. This demonstrates a privilege escalation vulnerability where authenticated users with administrative capabilities can leverage the flaw to execute commands beyond their intended scope. Both attack vectors are categorized under CWE-89, which specifically addresses SQL injection vulnerabilities in software systems.
The operational impact of this vulnerability extends beyond simple data theft, encompassing complete system compromise and potential lateral movement within network environments. Remote attackers can exploit the unauthenticated SQL injection in search.php to execute arbitrary database commands, potentially leading to data manipulation, unauthorized access to sensitive information, and even database server compromise. The authenticated administrator vector poses additional risks as it allows malicious insiders or compromised administrator accounts to escalate privileges and execute commands with elevated database permissions. These vulnerabilities align with ATT&CK technique T1071.004, which covers application layer protocol manipulation, and T1566, which addresses credential harvesting through various attack vectors. The impact on organizations using phpMyRealty could include financial data theft, customer information compromise, and complete database corruption.
Mitigation strategies for CVE-2007-6472 require immediate implementation of input validation and parameterized query usage throughout the application. Organizations should implement proper input sanitization techniques to ensure all user-supplied parameters are properly escaped or validated before being incorporated into database queries. The most effective defense involves transitioning from dynamic SQL query construction to parameterized queries or prepared statements, which prevent malicious input from altering the intended query structure. Additionally, implementing proper access controls and privilege separation ensures that even if one component is compromised, attackers cannot escalate privileges to administrative levels without proper authentication. Network segmentation and monitoring solutions should be deployed to detect unusual database activity patterns that might indicate exploitation attempts. Regular security assessments and vulnerability scanning should be conducted to identify similar flaws in other legacy applications, as this vulnerability represents a common class of issues that persisted in web applications throughout the early 2000s era. The vulnerability also underscores the importance of keeping web applications updated, as phpMyRealty 1.0.9 was an outdated version that had likely received no security updates, making it particularly susceptible to such attacks.
