CVE-2024-55998 identifies a missing authorization vulnerability in the Popup Surveys & Polls plugin for WordPress developed by Eric Sloan (Mare.io). This vulnerability stems from improperly configured access control mechanisms within the plugin, which is designed to create and manage popup surveys and polls on WordPress websites. Versions up to and including 1.36 are affected. The missing authorization means that certain actions or administrative functions within the plugin can be accessed or executed by unauthorized users, bypassing intended security checks. This can lead to unauthorized viewing, modification, or deletion of survey data or poll results, potentially compromising the integrity and confidentiality of the information collected. The vulnerability does not require user interaction, and no authentication is needed to exploit it, increasing the risk profile. Although no public exploits have been reported yet, the flaw presents a significant risk if weaponized. The plugin is commonly used on WordPress sites, which are widely deployed globally, making the vulnerability relevant to a broad audience. The lack of a CVSS score necessitates an expert severity assessment based on the impact and exploitability characteristics. The vulnerability highlights the importance of proper access control implementation in WordPress plugins, especially those handling user-generated content or data collection. Until a patch is released, administrators should consider restricting access to the plugin’s functionality via web application firewalls or manual configuration changes to limit exposure.

The primary impact of CVE-2024-55998 is unauthorized access to and manipulation of survey and poll data managed by the affected WordPress plugin. This can lead to data integrity issues, such as falsified poll results or survey responses, which may mislead decision-making processes relying on this data. Confidentiality may also be compromised if sensitive survey data is exposed to unauthorized parties. For organizations using this plugin on public-facing websites, the vulnerability could be exploited by attackers to disrupt user engagement, damage reputation, or conduct further attacks leveraging the compromised site. The ease of exploitation without authentication and user interaction increases the risk of automated or opportunistic attacks. While no known exploits exist yet, the vulnerability could be targeted by attackers seeking to manipulate data or gain footholds in WordPress environments. The scope of affected systems includes any WordPress installation running the vulnerable plugin version, which could be substantial given WordPress’s market share. The availability of the site or plugin functionality is less likely to be directly impacted but could be indirectly affected if attackers alter or delete critical data. Overall, the vulnerability poses a high risk to organizations relying on accurate and secure survey or poll data.

1. Monitor the plugin vendor’s official channels for a security patch and apply updates immediately once available. 2. Until a patch is released, restrict access to the plugin’s administrative interfaces using web application firewalls (WAFs) or IP whitelisting to limit exposure to trusted users only. 3. Review and harden WordPress user roles and permissions to ensure only authorized personnel can manage surveys and polls. 4. Conduct an audit of existing survey and poll data for signs of unauthorized access or manipulation. 5. Disable or remove the Popup Surveys & Polls plugin if it is not essential to reduce attack surface. 6. Implement logging and monitoring on WordPress sites to detect unusual activities related to the plugin. 7. Educate site administrators about the risks of installing plugins without proper security vetting and encourage regular plugin updates. 8. Consider deploying security plugins that enforce stricter access controls and detect unauthorized changes within WordPress environments.
