Horizon Alert
Summary of the vulnerability and why it matters
This advisory addresses a critical vulnerability in a content management system's search functionality, specifically when using MySQL or MariaDB databases. The flaw allows unauthenticated attackers to inject malicious SQL commands, potentially leading to unauthorized access, data modification, and even administrator privilege escalation. The primary concern is to confirm if your organization's web presence utilizes this specific search feature with the affected database configurations.
- Attackers can inject commands via website search.
- It allows full control of user accounts.
- Confirm relevance and identify exposure.
Attack Path
How an attacker could exploit the issue
An attacker can initiate an SQL injection attack by sending specially crafted input to the front-end search feature of a website using craft.search. This vulnerability, which affects MySQL/MariaDB databases, allows for stacked query execution due to unsanitized data concatenation and emulated prepares. Successful exploitation can lead to unauthorized access to the application's database, potentially allowing an attacker to escalate privileges to administrator level by modifying user roles or resetting passwords.
- Accessible via front-end search.
- Triggers via unsanitized input.
- Leads to database access and privilege escalation.
Live Threat
Current exploitation, exposure, and threat context
An unauthenticated SQL injection vulnerability could allow attackers to execute stacked queries on websites using `craft.search` with MySQL or MariaDB. This could lead to unauthorized read and write access to the application database, potentially enabling privilege escalation to administrator level or the modification of user credentials.
- Application database data.
- Unsanitized search parameter input.
- Unauthorized database access or account takeover.
Operational Fix
Recommended remediation, mitigation, and detection steps
The primary responsibility for addressing this SQL injection vulnerability likely falls to the application owner and potentially the platform team if the affected technology is managed as part of a shared service. The first practical step is to identify all instances of the affected search functionality, confirm its exposure and business criticality, and then coordinate remediation with the responsible team.
- Application owners should own the fix.
- Verify all exposed search endpoints.
- Plan updates during maintenance windows.
