The vulnerability identified as CVE-2012-5290 represents a critical security flaw in the EasyWebRealEstate web application that exposes multiple SQL injection attack vectors. This vulnerability affects the application's handling of user-supplied input parameters, specifically targeting the lstid parameter in listings.php and the infoid parameter in index.php. The flaw stems from inadequate input validation and sanitization mechanisms within the application's database interaction layers, creating pathways for malicious actors to manipulate database queries through crafted input values.
The technical implementation of this vulnerability aligns with CWE-89, which categorizes SQL injection as a code injection technique where untrusted data is incorporated into SQL queries without proper sanitization. When attackers manipulate the lstid or infoid parameters, they can inject malicious SQL commands that bypass authentication mechanisms and gain unauthorized access to sensitive database information. The vulnerability operates at the application layer where user input directly influences database query construction, making it particularly dangerous as it can be exploited without requiring prior authentication or elevated privileges. This type of attack falls under the ATT&CK technique T1071.004, which involves application layer protocol manipulation through SQL injection.
The operational impact of CVE-2012-5290 extends beyond simple data theft, as successful exploitation can lead to complete database compromise, unauthorized data modification, and potential lateral movement within affected networks. Attackers can leverage this vulnerability to extract confidential information such as user credentials, personal data, and business records stored in the application's database. The remote nature of the attack means that threat actors can exploit this vulnerability from anywhere on the internet without requiring physical access to the target system. The vulnerability affects the integrity and confidentiality of the web application's data, potentially leading to service disruption and regulatory compliance violations. Organizations using EasyWebRealEstate may face significant financial and reputational damage if this vulnerability is exploited, as it provides attackers with persistent access to sensitive information and potential pathways for further system compromise.
Mitigation strategies for CVE-2012-5290 should focus on implementing proper input validation and parameterized queries to prevent user-supplied data from being interpreted as SQL commands. The recommended approach involves upgrading to the patched version of EasyWebRealEstate that addresses these vulnerabilities, while also implementing web application firewalls and input sanitization mechanisms. Organizations should also conduct thorough security assessments to identify similar vulnerabilities in other applications and establish secure coding practices that prevent SQL injection attacks. Additionally, implementing database access controls and monitoring systems can help detect and prevent unauthorized database access attempts that may exploit this vulnerability. The remediation process should include comprehensive testing to ensure that all input parameters are properly validated and that the application no longer accepts malicious SQL commands through the affected parameters.
