Who should care
Defenders responsible for WordPress installations, especially those with untrusted or unauthenticated access, should assess exposure and prioritize remediation. This includes administrators, security teams, and IT personnel who manage WordPress installations. They should verify the plugin version, restrict access, and monitor for suspicious activity to prevent potential exploitation.
Why it matters
This vulnerability allows unauthenticated attackers to gain unauthorized access to WordPress installations, potentially leading to further exploitation or data breaches.
- Unauthenticated attackers can log in as any registered user, including administrators.
- Arbitrary new accounts can be created by unauthenticated attackers.
- Defenders should verify and remediate this vulnerability to prevent unauthorized access.
Technical summary
The advanced-customized-prompts WordPress plugin through 1.0.1 does not verify the password before issuing an authenticated session for a supplied email address in an unauthenticated action. This allows attackers to gain unauthorized access to WordPress installations without needing to know the password, potentially leading to further exploitation or data breaches. The vulnerability is due to a lack of proper authentication checks in the plugin's code, which can be exploited by sending a crafted request to the affected plugin.
Defensive priority
Defenders should prioritize verifying and remediating this vulnerability in their WordPress installations, especially those with untrusted or unauthenticated access.
Recommended defensive actions
- Verify the version of the advanced-customized-prompts WordPress plugin and update to a patched version if available.
- Restrict access to the WordPress installation to trusted users and networks.
- Monitor for suspicious login attempts and account creations.
- Implement additional security measures such as two-factor authentication or IP blocking.
- Conduct regular security audits to identify potential vulnerabilities.
- Review and update incident response plans to address potential exploitation.
- Consider using a Web Application Firewall (WAF) to detect and prevent exploitation attempts.
Evidence notes
The CVE record and NVD entry provide details on the vulnerability, but additional information on affected versions, exploitation, and remediation may be limited. Defenders should verify the plugin version and check for any available patches or updates. The lack of password verification allows for easy exploitation, and defenders should be cautious of potential unauthorized access.
