- Resulting Risk: Unauthenticated administrative access and control.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an unauthenticated attacker to log in as an administrative user by bypassing authentication checks. This could be achieved if the attacker has a pre-existing account on the site, which can be created by default through temporary user functionality. The attacker could then gain access to the administrative user's email.
- Administrative user accounts.
- Unauthenticated bypass of login.
- Unauthorized access to user email.
Operational Fix
Recommended remediation, mitigation, and detection steps
The FindAll Membership plugin for WordPress is vulnerable to authentication bypass, allowing unauthenticated attackers to log in as administrative users. This requires the attacker to have an existing account on the site, which can be easily created. The first practical step is for the website's owner or administrator to identify all instances of the affected plugin, determine their exposure to the internet, and assess their business criticality. Based on this risk assessment, a remediation plan should be developed, which may involve coordinating with the vendor or implementing temporary risk reduction measures.
- Website owners should own the issue.
- Verify plugin presence and exposure.
- Plan remediation based on risk.
