Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability affects a database plugin for Grav CMS, a content management system. It allows an attacker to execute arbitrary SQL commands if they can control specific input, potentially leading to unauthorized access or manipulation of the database. The primary concern is confirming whether this plugin is in use and if it's exposed to potential threats.
- Plugin allows SQL injection via database interaction.
- Critical if Grav CMS is publicly accessible.
- Confirm use and exposure of this plugin.
Attack Path
How an attacker could exploit the issue
An attacker could reach this vulnerability by sending specially crafted input to a Grav CMS website that uses the database plugin. If a consuming plugin or custom code passes an attacker-controlled table name to the vulnerable function, it can lead to arbitrary SQL execution. This could result in unauthorized access to or modification of sensitive database information.
- No authentication required.
- Vulnerable PDO::tableExists method.
- Arbitrary SQL execution possible.
Live Threat
Current exploitation, exposure, and threat context
When supported by the advisory, malicious actors could execute arbitrary SQL commands against the configured database by crafting specific table names. This could potentially affect database integrity and lead to unauthorized data access or manipulation, depending on the privileges granted to the database user.
- Database contents could be compromised.
- Malicious SQL could be injected.
- Unauthorized data access or modification.
Operational Fix
Recommended remediation, mitigation, and detection steps
The grav-plugin-database vulnerability impacts Grav CMS installations, likely managed by web application or platform teams. The first step is to inventory Grav instances, confirm exposure and business criticality, and identify the accountable owner before planning remediation based on risk.
- Application owners must address the vulnerability.
- Verify affected Grav instances and exposure.
- Plan remediation based on risk.
