CVE-2022-42909 in Print Away
Summary
by MITRE • 02/03/2023
WEPA Print Away does not verify that a user has authorization to access documents before generating print orders and associated release codes. This could allow an attacker to generate print orders and release codes for documents they don´t own and print hem without authorization. In order to exploit this vulnerability, the user must have an account with wepanow.com or any of the institutions they serve, and be logged in.

The vulnerability identified as CVE-2022-42909 affects the WEPA Print Away system, a document management and printing solution used by educational institutions and organizations. This authorization flaw represents a significant security weakness that undermines the integrity of document access controls within the platform. The system's failure to properly validate user permissions before processing print requests creates an avenue for unauthorized document access and printing operations. The vulnerability specifically targets the document release code generation mechanism, where the system generates print orders and associated release codes without verifying that the requesting user has legitimate authorization to access the target documents.
The technical implementation of this flaw stems from inadequate input validation and access control mechanisms within the WEPA Print Away application. When users attempt to print documents, the system should perform authentication checks to confirm that the user has proper permissions to access the requested materials. However, the current implementation bypasses these critical verification steps, allowing authenticated users to generate print orders for documents they do not own. This represents a classic authorization bypass vulnerability that falls under the CWE-285 category of improper authorization controls. The vulnerability manifests when the system generates release codes and print orders without cross-referencing the user's access rights against the document's permission settings.
The operational impact of this vulnerability extends beyond simple unauthorized document access, creating potential risks for data confidentiality and institutional security. An attacker with a valid account can exploit this weakness to print sensitive documents belonging to other users, potentially including personal information, academic records, or proprietary materials. The attack requires only a valid account and authentication, making it accessible to both malicious insiders and external attackers who may have obtained legitimate credentials through various means. This vulnerability directly violates the principle of least privilege and can lead to information disclosure, privacy violations, and potential compliance breaches under regulations such as FERPA for educational institutions. The release code generation process becomes a vector for unauthorized document consumption, effectively bypassing the intended access control framework.
Mitigation strategies for this vulnerability should focus on implementing robust access control validation at the point of print order generation. Organizations should ensure that the WEPA Print Away system performs comprehensive authorization checks before creating any print orders or release codes, verifying that the authenticated user has explicit permission to access the requested documents. The system should maintain detailed audit logs of all print activities and implement real-time monitoring for suspicious patterns. Security patches should address the core authorization bypass by strengthening the document access control layer and ensuring that all print operations are preceded by proper permission validation. Additionally, organizations should consider implementing role-based access controls, regular security assessments, and user behavior analytics to detect and prevent unauthorized access attempts. The remediation efforts should align with cybersecurity frameworks such as NIST SP 800-53 controls for access control and audit logging, ensuring comprehensive protection against similar authorization bypass threats.
