The CVE-2010-1075 vulnerability represents a critical sql injection flaw within the Entry Level CMS (EL CMS) content management system that exposes the application to remote code execution attacks. This vulnerability specifically targets the index.php file and exploits an insecure input handling mechanism through the subj parameter, which serves as a direct conduit for malicious sql commands to be injected into the backend database layer. The vulnerability falls under the common weakness enumeration CWE-89 which categorizes sql injection as a fundamental flaw in application security where untrusted data is directly incorporated into sql queries without proper sanitization or parameterization.
The technical exploitation of this vulnerability occurs when an attacker crafts a malicious payload containing sql code within the subj parameter of the index.php script. When the cms processes this input without proper validation or escaping mechanisms, the injected sql commands are executed within the context of the database connection, potentially allowing attackers to extract sensitive data, modify database contents, or even escalate privileges to gain administrative control over the cms installation. The attack vector is particularly dangerous because it requires no authentication and can be executed remotely, making it a prime target for automated exploitation tools and malicious actors seeking to compromise web applications.
The operational impact of CVE-2010-1075 extends beyond simple data theft, as successful exploitation can lead to complete system compromise and persistent backdoor access. Attackers can leverage this vulnerability to establish a foothold within the organization's infrastructure, potentially using the compromised cms as a launching point for further attacks against internal network resources. The vulnerability also poses significant risks to data integrity and confidentiality, as unauthorized users can manipulate database contents, delete critical information, or extract sensitive user credentials and personal data stored within the cms database. Organizations using EL CMS versions affected by this vulnerability face potential regulatory compliance violations and significant reputational damage if sensitive information is compromised.
Mitigation strategies for CVE-2010-1075 should prioritize immediate patching of the affected EL CMS installations, as the vulnerability has been widely documented and patched by the vendor. Organizations should implement proper input validation and parameterized queries throughout their applications to prevent similar vulnerabilities from occurring in the future, adhering to secure coding practices recommended by the open web application security project owasp and the defense in depth principles outlined in the mitre attack framework. Additionally, network segmentation, web application firewalls, and regular security assessments should be deployed to reduce the attack surface and detect potential exploitation attempts. The vulnerability also highlights the importance of keeping all cms components updated and following security best practices such as the principle of least privilege and regular security audits to prevent similar sql injection attacks from compromising system integrity and data security.
