CVE-2024-54389 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Eduardo addWeather plugin, specifically affecting versions up to and including 2.5.1. CSRF vulnerabilities occur when a web application does not properly verify that requests made to it originate from an authenticated and authorized user, allowing attackers to craft malicious requests that execute actions on behalf of the user without their knowledge. In this case, the addWeather plugin fails to implement adequate anti-CSRF tokens or similar protections, enabling attackers to induce authenticated users to perform unintended operations, such as modifying weather settings or configurations. The vulnerability affects all versions up to 2.5.1, with no patch currently linked or available in the provided data. While no known exploits are reported in the wild, the vulnerability's presence in a widely used plugin for weather information integration presents a risk vector for web applications that rely on it. The absence of a CVSS score necessitates an assessment based on the nature of CSRF attacks, which typically require the victim to be authenticated but do not require complex exploitation techniques. The vulnerability primarily threatens the integrity of the affected systems by allowing unauthorized changes and could also impact availability if critical configurations are altered maliciously.

The primary impact of this CSRF vulnerability is on the integrity of affected web applications using the Eduardo addWeather plugin. Attackers can perform unauthorized actions on behalf of authenticated users, potentially altering plugin settings or causing unintended behavior. This can lead to misinformation being displayed, disruption of service, or further exploitation if combined with other vulnerabilities. Organizations relying on this plugin for weather data display or related functionalities may experience compromised user trust, service disruptions, or reputational damage. Since exploitation requires the user to be authenticated, the scope is limited to users with sufficient privileges, but the ease of exploitation through social engineering (e.g., phishing links) increases risk. The lack of known exploits in the wild reduces immediate threat but does not eliminate the risk of future attacks. Overall, the vulnerability could be leveraged in targeted attacks against websites using this plugin, especially those with high user interaction or administrative access.

To mitigate the risk posed by CVE-2024-54389, organizations should first verify if they are using the Eduardo addWeather plugin, particularly versions up to 2.5.1. If so, they should monitor for official patches or updates from the vendor and apply them promptly once available. In the absence of an immediate patch, implementing web application firewall (WAF) rules to detect and block suspicious CSRF attempts can reduce risk. Additionally, enforcing strict same-site cookie attributes and requiring re-authentication for sensitive actions within the plugin can help mitigate exploitation. Developers and administrators should audit the plugin’s code to ensure anti-CSRF tokens are properly implemented on all state-changing requests. User education about the risks of clicking on untrusted links while authenticated can also reduce the likelihood of successful attacks. Finally, regular security assessments and penetration testing focusing on CSRF and related vulnerabilities in web applications using this plugin are recommended.
