The CVE-2017-17591 vulnerability represents a critical sql injection flaw in the Realestate Crowdfunding Script version 2.7.2, specifically targeting the single-cause.php page through the pid parameter. This vulnerability falls under the common weakness enumeration CWE-89 which categorizes sql injection as a fundamental web application security flaw. The flaw occurs when user input from the pid parameter is directly incorporated into sql query construction without proper sanitization or parameterization, creating an exploitable entry point for malicious actors to manipulate database operations.
The technical implementation of this vulnerability allows an attacker to inject malicious sql code through the pid parameter, potentially enabling unauthorized access to sensitive database information. When the application processes the pid parameter in the single-cause.php script, it fails to properly validate or escape user-supplied input before incorporating it into database queries. This creates opportunities for attackers to execute arbitrary sql commands, potentially leading to data theft, modification, or deletion. The vulnerability specifically affects the crowdfunding script's ability to handle single cause page requests, making it particularly dangerous for applications processing financial or personal data related to real estate investments.
The operational impact of this vulnerability extends beyond simple data exposure, as it can enable complete database compromise and potentially lead to full system takeover. Attackers can leverage this flaw to extract sensitive information including user credentials, financial records, personal identification details, and investment data. The vulnerability also supports privilege escalation attacks where malicious actors might gain administrative access to the application's backend systems. From an att&ck framework perspective, this vulnerability maps to techniques such as credential access and defense evasion, as attackers can use the compromised system to maintain persistence and access additional resources. The impact is particularly severe for crowdfunding platforms where financial transactions and personal data are processed, as successful exploitation could result in significant financial loss and regulatory compliance violations.
Mitigation strategies for CVE-2017-17591 should prioritize immediate implementation of parameterized queries and input validation mechanisms. The most effective remediation involves implementing proper sql prepared statements that separate sql logic from user input, ensuring that the pid parameter cannot influence query structure. Additionally, input validation should be enforced through strict whitelisting of acceptable parameter values and comprehensive output encoding to prevent malicious code execution. Organizations should also implement web application firewalls and database activity monitoring to detect and prevent exploitation attempts. Regular security assessments and vulnerability scanning should be conducted to identify similar flaws in other application components, as sql injection vulnerabilities often exist in multiple locations within complex web applications. The remediation process must include thorough code review to ensure all parameterized inputs are properly sanitized and that the application follows secure coding practices aligned with industry standards such as owasp top ten and iso 27001 security requirements.
