This flaw allows remote attackers to inject malicious SQL queries into the application\u0026rsquo;s database without requiring any prior authentication. The vulnerability resides within the component responsible for handling form submissions, specifically the \u0026lsquo;com_baforms\u0026rsquo; component. By sending crafted POST requests containing malicious JSON payloads in the \u0026lsquo;id\u0026rsquo; field, attackers can bypass input validation and directly interact with the database. Successful exploitation of this vulnerability enables attackers to extract sensitive data such as user credentials, application configurations, and other confidential information stored within the Joomla database. This vulnerability poses a significant risk to organizations using the affected Balbooa Joomla Forms Builder version, potentially leading to data breaches and unauthorized access to critical systems.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a Joomla website using Balbooa Forms Builder 2.0.6.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious POST request targeting the com_baforms component.\u003c/li\u003e\n\u003cli\u003eThe POST request includes a JSON payload with a manipulated \u0026lsquo;id\u0026rsquo; parameter containing SQL injection code.\u003c/li\u003e\n\u003cli\u003eThe application fails to properly sanitize the \u0026lsquo;id\u0026rsquo; parameter before using it in a database query.\u003c/li\u003e\n\u003cli\u003eThe injected SQL code is executed against the Joomla database.\u003c/li\u003e\n\u003cli\u003eThe attacker extracts sensitive information from the database, such as user credentials or configuration details.\u003c/li\u003e\n\u003cli\u003eThe extracted information can then be used for further malicious activities such as lateral movement or data exfiltration.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2021-47930 can lead to a complete compromise of the Joomla application and its underlying database.
