The CVE-2016-10965 vulnerability resides within the real3d-flipbook-lite plugin version 1.0 for WordPress, representing a critical directory traversal flaw that enables unauthorized file deletion operations. This vulnerability specifically manifests through the deleteBook parameter within the plugin's functionality, allowing attackers to manipulate file paths and potentially remove arbitrary files from the target system. The flaw stems from insufficient input validation and sanitization of user-supplied parameters, creating a pathway for malicious actors to exploit the plugin's file deletion mechanism.
The technical implementation of this vulnerability follows a classic directory traversal pattern where the deleteBook parameter accepts user input without proper sanitization or validation. When an attacker crafts a malicious request containing directory traversal sequences such as "../", the plugin processes these inputs directly without proper path validation, enabling the deletion of files outside the intended directory scope. This represents a CWE-22 directory traversal vulnerability that violates the principle of least privilege and proper input validation. The vulnerability operates at the application layer and can be exploited through web-based attacks, making it particularly dangerous in web server environments.
The operational impact of CVE-2016-10965 extends beyond simple file deletion, as it can lead to complete system compromise and data loss. An attacker with access to the plugin's administrative interface or the ability to submit malicious requests can potentially delete critical system files, configuration files, or even the entire WordPress installation. This vulnerability can be leveraged as part of a broader attack chain, enabling further exploitation through the compromise of other system components. The attack vector typically involves crafting specially formatted URLs with the deleteBook parameter containing directory traversal sequences, which when processed by the vulnerable plugin, results in unauthorized file deletion operations.
Mitigation strategies for this vulnerability require immediate patching of the affected plugin to version 1.1 or later, which includes proper input validation and sanitization measures. System administrators should implement strict input validation on all user-supplied parameters, particularly those used for file operations. The principle of least privilege should be enforced by limiting the web server's file system permissions and ensuring that the WordPress installation directory has restricted write access. Additionally, implementing web application firewalls and input filtering mechanisms can help detect and prevent malicious directory traversal attempts. Security monitoring should be enhanced to detect unusual file deletion patterns and unauthorized access attempts to the plugin's functionality. Organizations should also conduct regular security assessments of their WordPress installations and maintain updated vulnerability management processes to prevent similar issues from occurring in other plugins or components.
