CVE-2024-12572 is a security vulnerability classified as CWE-352 (Cross-Site Request Forgery) found in the Hello In All Languages plugin for WordPress, affecting all versions up to and including 1.0.6. The vulnerability stems from missing or incorrect nonce validation in a plugin function responsible for updating settings. Nonces in WordPress are security tokens used to verify that requests originate from legitimate users and not from forged sources. Without proper nonce validation, attackers can craft malicious requests that, when executed by an authenticated administrator (via clicking a link or visiting a crafted webpage), cause unauthorized changes to plugin settings or injection of malicious web scripts. This attack vector does not require the attacker to be authenticated but does require user interaction from an administrator, making social engineering a key component. The vulnerability impacts the confidentiality and integrity of the affected WordPress site by enabling unauthorized configuration changes and potential script injection, which could lead to further compromise or data leakage. The CVSS 3.1 base score is 6.1, indicating a medium severity level, with an attack vector of network (remote), low attack complexity, no privileges required, user interaction required, and a scope change due to the potential for privilege escalation or broader impact. No patches or exploit code are currently publicly available, but the vulnerability is published and should be addressed promptly.

The impact of CVE-2024-12572 on organizations worldwide can be significant, especially for those relying on the Hello In All Languages plugin for multilingual support on WordPress sites. Successful exploitation allows attackers to alter plugin settings and inject malicious scripts, which can lead to unauthorized access, data leakage, defacement, or further malware deployment. This compromises the confidentiality and integrity of the website and potentially its users' data. Since WordPress powers a large portion of the web, including many business, governmental, and e-commerce sites, the vulnerability could be leveraged in targeted attacks or widespread campaigns. The requirement for administrator interaction limits mass exploitation but does not eliminate risk, as phishing or social engineering can be effective. Organizations with high web presence or sensitive data hosted on WordPress platforms are at greater risk. Additionally, compromised sites could be used as launch points for broader attacks or to distribute malware, amplifying the threat's impact.

To mitigate CVE-2024-12572, organizations should take the following specific actions: 1) Immediately update the Hello In All Languages plugin to a version that includes proper nonce validation once available; if no patch exists yet, consider temporarily disabling the plugin to prevent exploitation. 2) Implement strict administrative access controls, including limiting the number of users with admin privileges and enforcing strong authentication mechanisms such as multi-factor authentication (MFA). 3) Educate site administrators about the risks of phishing and social engineering attacks that could trick them into clicking malicious links. 4) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the vulnerable plugin endpoints. 5) Regularly audit and monitor WordPress logs for unusual administrative actions or configuration changes. 6) Consider isolating critical WordPress administrative interfaces behind VPNs or IP whitelisting to reduce exposure. 7) Use security plugins that can detect unauthorized changes or script injections to enable rapid response. These measures combined reduce the likelihood of successful exploitation and limit potential damage.
