CVE-2022-0616 in Amelia Plugin
Summary
by MITRE • 03/21/2022
The Amelia WordPress plugin before 1.0.47 does not have CSRF check in place when deleting customers, which could allow attackers to make a logged in admin delete arbitrary customers via a CSRF attack

The CVE-2022-0616 vulnerability resides within the Amelia WordPress plugin, specifically affecting versions prior to 1.0.47, where a critical security flaw exists in the customer deletion functionality. This issue represents a classic cross-site request forgery vulnerability that exploits the absence of proper validation mechanisms within the plugin's administrative interface. The vulnerability allows authenticated attackers who have gained access to an administrator's session to manipulate the plugin's customer management system through maliciously crafted requests. When an administrator visits a compromised website or clicks on a malicious link, the attacker can leverage the missing CSRF protection to execute unauthorized customer deletion operations without the administrator's knowledge or consent.
The technical flaw stems from the plugin's failure to implement proper anti-CSRF measures when processing customer deletion requests. In a typical CSRF attack scenario, the malicious actor crafts a request that appears to originate from a legitimate administrator session, but lacks the necessary validation tokens that would normally verify the authenticity of the request. This absence of CSRF protection means that any authenticated user with administrative privileges can be tricked into performing customer deletion actions through carefully constructed web requests that bypass normal security controls. The vulnerability is particularly dangerous because it operates at the administrative level, allowing attackers to compromise customer data and potentially disrupt business operations.
The operational impact of this vulnerability extends beyond simple data loss, as unauthorized customer deletion can lead to significant business disruption and potential regulatory compliance issues. Administrators may unknowingly delete customer records, leading to data integrity problems, loss of customer relationships, and potential revenue impact. The vulnerability also creates opportunities for attackers to perform additional malicious activities such as customer data manipulation or system disruption. From a compliance perspective, unauthorized deletion of customer records could violate data protection regulations and industry standards such as gdpr, pci dss, and other data governance frameworks that require proper audit trails and data integrity controls. The attack vector is particularly insidious because it requires minimal privileges beyond an existing administrative session, making it difficult to detect and prevent.
Mitigation strategies for this vulnerability should include immediate patching to version 1.0.47 or later, which implements proper CSRF protection mechanisms. Organizations should also implement additional security controls such as role-based access restrictions, enhanced monitoring of administrative activities, and regular security auditing of WordPress plugins. The implementation of proper CSRF tokens and validation checks aligns with established security practices outlined in the CWE-352 category, which specifically addresses cross-site request forgery vulnerabilities. Security teams should also consider implementing web application firewalls to detect and block suspicious requests, along with regular vulnerability scanning to identify similar issues in other plugins or components. The ATT&CK framework categorizes this type of vulnerability under privilege escalation and persistence techniques, making it a significant concern for organizations seeking to maintain robust security postures against sophisticated attack vectors.
