This vulnerability represents a critical sql injection flaw in the woocommerce quote calculator plugin version 1.1 and earlier, specifically within the woo-quote-calculator-order component. The weakness stems from improper sanitization of user input before incorporating it into sql command structures, creating an avenue for malicious actors to manipulate database queries through crafted input parameters. The vulnerability is classified as blind sql injection because attackers cannot directly observe database responses but can infer information through indirect means such as timing variations or conditional responses, making detection more challenging for system administrators.
The technical implementation of this flaw occurs when user-supplied data enters the sql query execution path without adequate validation or escaping mechanisms. Attackers can exploit this by injecting malicious sql payloads through input fields that are processed by the plugin's order handling functionality. This allows unauthorized individuals to extract database contents, modify data, or potentially escalate privileges within the affected system. The vulnerability's impact is amplified by the fact that it affects the core order processing functionality of the woocommerce platform, which typically handles sensitive customer and transactional data.
From an operational perspective, this vulnerability poses significant risks to e-commerce platforms using the affected plugin, as it could lead to complete database compromise and unauthorized access to customer information, order details, and potentially payment data. The blind nature of the injection means that attackers can systematically probe the database structure and extract information through time-based or boolean-based techniques without direct error messages. This makes the vulnerability particularly dangerous for systems where database integrity and customer privacy are paramount concerns. The issue affects all versions up to and including 1.1, indicating that users running these older versions remain at risk.
Security mitigation strategies should focus on immediate patching of the affected plugin to version 1.2 or later, which should contain proper input sanitization and parameterized query implementations. Organizations should also implement web application firewalls to monitor for suspicious sql injection patterns and conduct thorough penetration testing to identify similar vulnerabilities in other plugins or custom code. Additionally, database access controls should be reviewed to ensure least privilege principles are applied, limiting the potential damage from any successful exploitation attempts. This vulnerability aligns with common weakness enumeration cwes 89 and 74, which specifically address sql injection vulnerabilities and improper neutralization of special elements in sql commands, respectively. The attack surface is consistent with typical sql injection attack patterns found in the mitre att&ck framework under the command and control and credential access phases, where adversaries seek to maintain persistence and extract sensitive information from compromised systems.
