The vulnerability identified as unauthenticated broken access control in ez Form Calculator Premium versions up to 2.14.1.2 represents a critical security flaw that undermines the application's authorization mechanisms. This issue allows attackers to bypass authentication requirements and gain unauthorized access to protected functionality within the plugin. The vulnerability stems from insufficient validation of user permissions and lack of proper access controls for administrative features, enabling malicious actors to perform actions they should not be authorized to execute without proper credentials.
The technical implementation flaw manifests in the plugin's handling of API endpoints and administrative functions that should require authenticated access. Attackers can exploit this weakness by directly calling specific URLs or endpoints that control calculator configurations, form settings, and other sensitive administrative operations. The vulnerability does not require any valid user credentials or session management to exploit, making it particularly dangerous as it can be leveraged by anyone with access to the web application. This represents a direct violation of the principle of least privilege and proper access control enforcement.
The operational impact of this vulnerability extends beyond simple unauthorized access to encompass potential data compromise, configuration manipulation, and service disruption. Attackers could modify calculator formulas, alter form submissions, manipulate calculation results, or even inject malicious code into the application's processing pipeline. The consequences are particularly severe in environments where financial calculations or sensitive data processing occurs through the calculator plugin. Additionally, this vulnerability could serve as a foothold for further attacks within the WordPress ecosystem, potentially leading to full system compromise.
Security professionals should prioritize immediate remediation of this issue by updating to version 2.14.1.3 or later, which includes proper authentication checks and access control enforcement. The vulnerability aligns with CWE-285, which specifically addresses improper authorization in software systems, and corresponds to ATT&CK technique T1078.004 for valid accounts and T1068 for exploit for privilege escalation. Organizations should also implement network segmentation, monitor for suspicious API access patterns, and conduct regular security assessments to identify similar authorization flaws in other plugins or custom applications. The incident highlights the critical importance of implementing robust access control mechanisms and conducting thorough security testing before deploying web applications that handle sensitive operations.
