CVE-2024-31263

Root

Cause A Cross-Site Request Forgery (CSRF) vulnerability exists in the aerin Loan Repayment Calculator and Application Form plugin for WordPress, affecting versions from n/a through 2.9.4 [1]. The plugin fails to properly validate or include anti-CSRF tokens in sensitive requests, allowing attackers to craft malicious requests that can be executed on behalf of an authenticated administrator without their consent [1].

Attack

Vector To exploit this vulnerability, an attacker must socially engineer a privileged user—such as an administrator—to click a crafted link, visit a malicious page, or submit a specially designed form while logged into the WordPress admin [1]. No direct authentication is needed from the attacker, but victim user interaction is required [1].

Impact

Successful exploitation could allow an unauthenticated attacker to force a higher-privileged user to perform unintended actions under their current session, such as modifying plugin settings or initiating unwanted operations [1]. This CSRF weakness is part of a broader class of vulnerabilities often leveraged in mass exploitation campaigns against WordPress sites [1].

Mitigation

The issue has been addressed in version 2.9.5 of the plugin [1]. Users are strongly advised to update to this version or enable auto-updates if using Patchstack. For those unable to update, requesting assistance from hosting providers or web developers is recommended [1].
