CVE-2024-3601 in Poll Maker Plugin
Summary
by MITRE • 05/02/2024
The Poll Maker – Best WordPress Poll Plugin plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the ays_poll_create_author function in all versions up to, and including, 5.1.8. This makes it possible for unauthenticated attackers to extract email addresses by enumerating them one character at a time.

The vulnerability identified as CVE-2024-3601 affects the Poll Maker - Best WordPress Poll Plugin, a widely used WordPress plugin that enables users to create interactive polls and surveys. This particular flaw resides within the ays_poll_create_author function, which fails to implement proper capability checks before allowing data access operations. The absence of authentication verification creates a critical security gap that can be exploited by malicious actors without requiring any valid credentials or user privileges to access sensitive information.
The technical nature of this vulnerability stems from a missing capability check that should have been implemented to verify user permissions before executing data retrieval operations. According to CWE-284, this represents an inadequate access control mechanism where the plugin fails to properly validate whether the requesting user possesses the necessary privileges to access specific data. The vulnerability allows unauthenticated attackers to perform data enumeration attacks against email addresses stored within the plugin's database, exploiting a fundamental flaw in the authorization process that should have been enforced at the function level.
The operational impact of this vulnerability is significant as it enables attackers to systematically extract email addresses through character-by-character enumeration techniques. This type of data exposure can lead to various downstream security issues including email harvesting for spam campaigns, social engineering attacks, and potential credential stuffing attempts against users whose email addresses have been compromised. The vulnerability affects all versions up to and including 5.1.8, indicating that a substantial portion of users may be exposed to this risk, particularly given the plugin's widespread adoption across WordPress installations.
From an attacker's perspective, this vulnerability aligns with ATT&CK technique T1213.002 which involves data from local systems and T1566.001 which covers credential harvesting through social engineering. The flaw provides attackers with a method to gather user information without requiring any legitimate access or credentials, making it particularly dangerous for organizations that rely on the plugin for user engagement and data collection. The enumeration process allows for precise targeting of user email addresses, which can then be used for targeted phishing campaigns or other malicious activities.
The recommended mitigation strategy involves immediate updating of the plugin to the latest available version where the capability check has been properly implemented. System administrators should also conduct thorough security assessments of their WordPress installations to identify any other plugins that may be vulnerable to similar access control flaws. Additionally, implementing network-level monitoring to detect unusual data access patterns and conducting regular security audits of WordPress plugins can help prevent exploitation of similar vulnerabilities. The fix should ensure that all functions requiring access to user data properly validate user capabilities before executing any data retrieval operations, thereby preventing unauthorized access to sensitive information.
