The CVE-2018-7463 vulnerability represents a critical SQL injection flaw within the ASANHAMAYESH CMS version 3.4.6, specifically affecting the files component's handling of user input. This vulnerability resides in the files.php script where the "id" parameter is processed without proper sanitization or validation, creating an exploitable entry point for malicious actors. The issue manifests when the application fails to adequately filter or escape user-supplied data before incorporating it into database queries, thereby allowing attackers to manipulate the underlying SQL execution logic.
The technical exploitation of this vulnerability occurs through the manipulation of the "id" parameter in the files.php script, where an attacker can inject malicious SQL code that gets executed within the database context. This type of injection vulnerability falls under CWE-89, which specifically addresses SQL injection flaws in software systems. The vulnerability enables remote code execution capabilities as attackers can craft malicious payloads that bypass authentication mechanisms, extract sensitive data, modify database records, or even gain complete control over the database server. The attack vector is particularly dangerous because it requires no authentication and can be executed from any remote location, making it highly attractive to threat actors.
The operational impact of CVE-2018-7463 extends beyond simple data theft, as it provides attackers with the capability to perform comprehensive database manipulation and potentially escalate privileges within the CMS environment. Organizations utilizing ASANHAMAYESH CMS 3.4.6 face significant risk of data breaches, system compromise, and potential service disruption. The vulnerability can be exploited to access confidential user information, including personal details, login credentials, and other sensitive data stored within the CMS database. Additionally, attackers may leverage this vulnerability to establish persistent backdoors or deploy additional malware within the compromised system, creating long-term security risks for the affected organization.
Mitigation strategies for CVE-2018-7463 should prioritize immediate patching of the ASANHAMAYESH CMS to version 3.4.7 or later, which contains the necessary security fixes for this vulnerability. Organizations should implement proper input validation and parameterized queries throughout their applications to prevent similar issues in the future. The principle of least privilege should be enforced by ensuring database connections use restricted user accounts with minimal required permissions. Network segmentation and intrusion detection systems can help identify potential exploitation attempts, while regular security audits and penetration testing should be conducted to verify the effectiveness of implemented controls. This vulnerability aligns with ATT&CK technique T1071.004, which covers application layer protocol manipulation, and demonstrates the importance of proper input sanitization as outlined in the OWASP Top Ten security principles.
