CVE-2023-6565 in InfiniteWP Client Plugin
Summary
by MITRE • 02/29/2024
The InfiniteWP Client plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.12.3 via the multi-call backup option. This makes it possible for unauthenticated attackers to extract sensitive data from a temporary SQL file via repeated GET requests during the limited time window of the backup process.

The InfiniteWP Client plugin for WordPress presents a significant security vulnerability classified as sensitive information exposure affecting versions up to and including 1.12.3. This flaw resides within the plugin's multi-call backup functionality, creating a pathway for unauthenticated attackers to access confidential data through repeated GET requests during the backup operation's limited time window. The vulnerability represents a critical weakness in the plugin's access control mechanisms and data handling procedures.
The technical implementation of this vulnerability stems from inadequate protection of temporary backup files during the multi-call backup process. When the backup operation executes, it generates temporary SQL files containing sensitive database information that remain accessible to external parties without proper authentication. The attacker can repeatedly submit GET requests to access these temporary files, exploiting the window of opportunity during which backup processes are active. This design flaw allows unauthorized data extraction from what should be protected administrative resources.
The operational impact of this vulnerability extends beyond simple data exposure, as it provides attackers with access to potentially sensitive information including database structures, user credentials, and system configurations. The vulnerability affects WordPress installations using the InfiniteWP Client plugin, making it particularly concerning for organizations relying on this management tool for multiple site administration. Attackers can leverage this weakness to gain insights into system architecture and potentially escalate privileges or conduct further reconnaissance activities.
This vulnerability aligns with CWE-200, which addresses the exposure of sensitive information to an unauthorized actor, and relates to ATT&CK technique T1213.002 for data from information repositories. The flaw demonstrates poor input validation and inadequate temporary file handling practices, creating an attack surface that should remain restricted to authenticated users only. Organizations using this plugin may face regulatory compliance issues if sensitive data is compromised through this vulnerability.
Mitigation strategies should prioritize immediate plugin updates to versions that address the backup process implementation and temporary file access controls. Administrators must also implement network-level restrictions to limit access to backup endpoints and consider disabling the multi-call backup functionality until proper security measures are in place. Additional protective measures include monitoring for unusual GET requests targeting backup directories and implementing proper access controls for temporary file storage. The vulnerability underscores the importance of secure temporary file management and proper authentication mechanisms in web applications.
