A vulnerability has been discovered in Joomla!, which could allow for SQL injection. This vulnerability exists due to inadequate filtering of request data in URL parameters. An attacker can exploit this issue by manipulating the SQL query logic in the URL bar in order to run SQL queries on the underlying database. (CVE-2017-8917)
Successful exploitation of this vulnerably could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
We recommend the following actions be taken:
- Apply appropriate patches provided by Joomla! to vulnerable systems immediately after appropriate testing.
- Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
