Component Ajax Quiz version 1.8. Threat actors can exploit this weakness by crafting specific GET requests to the \u003ccode\u003eindex.php\u003c/code\u003e endpoint, utilizing the \u003ccode\u003eoption=com_ajaxquiz\u003c/code\u003e and \u003ccode\u003eview=ajaxquiz\u003c/code\u003e parameters. By injecting malicious SQL code into the \u003ccode\u003ecid\u003c/code\u003e parameter, attackers can execute arbitrary SQL queries on the underlying database. This allows for the extraction of sensitive database information, including table names, column structures, and potentially confidential data, posing a significant risk to data confidentiality and integrity. The vulnerability stems from improper neutralization of special elements used in SQL commands.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eReconnaissance \u0026amp; Target Identification\u003c/strong\u003e: Attacker identifies a Joomla! instance running the vulnerable Ajax Quiz component version 1.8, often through automated scanning or public information.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eVulnerability Discovery\u003c/strong\u003e: Attacker identifies the \u003ccode\u003ecid\u003c/code\u003e parameter in GET requests to \u003ccode\u003eindex.php?option=com_ajaxquiz\u0026amp;view=ajaxquiz\u003c/code\u003e as a potential SQL injection point, either by probing or using known exploit patterns.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eInitial SQL Injection\u003c/strong\u003e: Attacker crafts a malicious GET request, such as \u003ccode\u003eGET /index.php?option=com_ajaxquiz\u0026amp;view=ajaxquiz\u0026amp;cid=1%20UNION%20SELECT%20NULL,user()--+\u003c/code\u003e, injecting an SQL payload into the \u003ccode\u003ecid\u003c/code\u003e parameter.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eArbitrary Query Execution\u003c/strong\u003e: The vulnerable component processes the request without properly sanitizing the \u003ccode\u003ecid\u003c/code\u003e parameter, leading to the execution of the injected SQL query by the backend database.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eDatabase Schema Enumeration\u003c/strong\u003e: Attacker sends follow-up requests with increasingly complex SQL payloads to enumerate database metadata, including table names and column structures, typically using \u003ccode\u003einformation_schema\u003c/code\u003e or similar system tables.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eSensitive Data Exfiltration\u003c/strong\u003e: Using the obtained database schema, the attacker crafts further SQL queries to extract sensitive information, such as user credentials, personal data, or proprietary business data from specific tables.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eImpact\u003c/strong\u003e: Compromised sensitive data is extracted from the database, leading to potential data breaches, unauthorized access, and further exploitation of the affected organization.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2017-20262 grants unauthenticated attackers the ability to execute arbitrary SQL queries on the backend database.
