The vulnerability identified as CVE-2015-10100 represents a critical sql injection flaw within the Dynamic Widgets WordPress plugin, specifically affecting versions through 1.5.10. This vulnerability resides in the file classes/dynwid_class.php and demonstrates a significant security weakness that allows remote attackers to manipulate database operations through crafted input. The issue stems from inadequate input validation and sanitization within the plugin's processing logic, creating an attack surface where malicious actors can inject arbitrary sql commands into the backend database. The vulnerability's classification as critical indicates the potential for severe impact including data theft, unauthorized access to sensitive information, and possible complete system compromise. The attack vector is remotely exploitable, meaning that threat actors do not require local access or authentication to initiate the malicious payload, making this vulnerability particularly dangerous in publicly accessible web environments.
The technical implementation of this sql injection vulnerability occurs when user-supplied data is not properly escaped or validated before being incorporated into database queries within the dynwid_class.php file. This allows attackers to manipulate the sql execution flow by injecting malicious sql fragments that can bypass authentication mechanisms, extract confidential data, modify database records, or even execute system commands depending on the underlying database configuration. The vulnerability's exploitation typically involves sending specially crafted requests that target parameters processed by the affected plugin components, where the input directly influences the sql query construction. According to industry standards, this vulnerability maps to CWE-89 sql injection, which is classified as a common weakness in software development practices where input validation is insufficient or absent. The ATT&CK framework would categorize this as a database injection technique under the command and control phase, potentially enabling further lateral movement within compromised systems.
The operational impact of CVE-2015-10100 extends beyond immediate data compromise to include potential system takeover and persistent access capabilities. Remote exploitation allows attackers to establish footholds within wordpress installations where the vulnerable plugin is deployed, potentially leading to complete site compromise and serving as a launching point for broader attacks against network infrastructure. The vulnerability's presence in a widely used plugin like Dynamic Widgets means that numerous wordpress sites could be simultaneously vulnerable, creating a significant attack surface for automated exploitation campaigns. Organizations running affected versions face risks of data breaches, regulatory compliance violations, and reputational damage. The vulnerability also poses risks to backup systems if attackers can manipulate database content, potentially corrupting recovery mechanisms and complicating incident response efforts. Additionally, the sql injection could enable attackers to escalate privileges within the database, potentially accessing other applications or systems that share the same database infrastructure.
Mitigation strategies for this vulnerability center on immediate remediation through the recommended upgrade to version 1.5.11, which incorporates the patch identified by the commit hash d0a19c6efcdc86d7093b369bc9e29a0629e57795. This upgrade addresses the root cause by implementing proper input sanitization and parameterized query construction within the affected file. Organizations should also implement additional protective measures including web application firewalls that can detect and block sql injection attempts, database query monitoring to identify suspicious activities, and comprehensive vulnerability scanning to ensure no other components remain vulnerable. Security teams should conduct thorough assessments of affected systems to verify successful patch application and monitor for any signs of exploitation attempts. The patch implementation should be followed by comprehensive testing to ensure that the upgrade does not introduce compatibility issues with existing site functionality or other plugins. Regular security monitoring and vulnerability management processes should be enhanced to prevent similar issues in the future, including implementing secure coding practices, regular code reviews, and automated testing for sql injection vulnerabilities. Organizations should also consider implementing network segmentation and access controls to limit the potential impact of successful exploitation attempts.
