SQL Injection in WordPress Forms Plugin Ajax Handler

Wow Forms WordPress Plugin version 2.1 contains an SQL injection vulnerability that allows unauthenticated attackers to read arbitrary database information by exploiting an unescaped POST parameter. Attackers can inject SQL code through the 'mwpformid' parameter in requests to the admin-ajax.php endpoint with the 'send_mwp_form' action to extract sensitive database contents.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2017-20244 is an unauthenticated SQL injection vulnerability in Wow Forms WordPress Plugin version 2.1 that allows attackers to execute arbitrary SQL queries against the application's database. The vulnerability exists in the admin-ajax.php endpoint where the 'mwpformid' POST parameter is passed directly to SQL queries without proper sanitization or parameterization. This is particularly critical because the vulnerable endpoint is accessible to unauthenticated users, enabling attackers to extract sensitive database contents including user credentials, personal information, and configuration data. Any organization using this plugin version is at immediate risk of data exfiltration and potential account compromise.

Casky's 301 mapped skills detect the attack patterns underlying this vulnerability across MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance), helping practitioners identify both the exploitation attempts and the reconnaissance activities that precede them. Practitioners using Casky would observe findings related to suspicious POST requests to admin-ajax.php with SQL syntax in parameter values, detection of database error messages in HTTP responses that confirm query execution, and patterns indicative of data exfiltration attempts. Claude's extended reasoning capabilities enable the platform to correlate these signals—such as unusual character encoding in parameters, timing-based SQL injection patterns, and database query anomalies—providing practitioners with contextual threat intelligence that distinguishes reconnaissance probing from active exploitation attempts.
