This vulnerability allows an attacker with valid administrator credentials to inject arbitrary SQL code into database queries. The vulnerability exists in the component responsible for sorting job listings. By sending a specially crafted POST request to the administrator index with a malicious ‘sortby’ value, an attacker can manipulate the underlying database queries and potentially extract sensitive information. This poses a significant risk to organizations using the vulnerable J2 JOBS component, as it could lead to data breaches, account compromise, or further exploitation of the Joomla application.

Attack Chain

  1. Attacker authenticates to the Joomla administrator panel.
  2. Attacker identifies the vulnerable J2 JOBS component’s index page.
  3. Attacker crafts a malicious POST request targeting the index page.
  4. The POST request includes the ‘sortby’ parameter with embedded SQL injection payload.
  5. The application fails to properly sanitize or validate the ‘sortby’ parameter.
  6. The application constructs a SQL query using the unsanitized ‘sortby’ value.
  7. The injected SQL code is executed by the database server.
  8. Attacker exfiltrates sensitive information extracted from the database.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2020-37226) can result in unauthorized access to sensitive data stored in the Joomla application’s database. This may include user credentials, financial information, or other confidential data. The impact can range from data breaches and reputational damage to financial losses and legal repercussions. Organizations using the vulnerable J2 JOBS 1.3.0 component are at risk.

Recommendation

  • Upgrade to a patched version of J2 JOBS that addresses the SQL injection vulnerability (CVE-2020-37226).
  • Deploy the Sigma rule Detect Joomla J2 JOBS SQL Injection via Sortby Parameter to detect exploitation attempts targeting the ‘sortby’ parameter in POST requests.
  • Monitor web server logs for suspicious POST requests to the Joomla administrator index containing potentially malicious SQL code within the ‘sortby’ parameter.
  • Implement input validation and sanitization measures on all user-supplied data, including URL parameters and POST request bodies, to prevent SQL injection attacks.
