Horizon Alert
Summary of the vulnerability and why it matters
This advisory highlights a critical vulnerability in the iCagenda Joomla extension that could allow unauthenticated attackers to inject malicious SQL code. This type of attack can potentially compromise the integrity and availability of data handled by the extension. The primary concern is to determine if this specific extension is in use and exposed to the internet.
- SQL injection in Joomla extension.
- Matters if the extension is public-facing.
- Confirm usage and exposure, then assess risk.
Attack Path
How an attacker could exploit the issue
An attacker can exploit this vulnerability by sending specially crafted requests to the vulnerable Joomla extension. Because the vulnerability is reachable through `com_ajax` without any session, token, or account, an attacker could potentially inject malicious SQL code into the application's database. This could lead to unauthorized access to sensitive information or manipulation of data.
- No authentication required.
- SQL injection via `com_ajax`.
- Risk of data compromise or alteration.
Live Threat
