Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability in Masa CMS allows attackers to access sensitive database information, including user credentials. It impacts the unauthenticated JSON API, meaning any unauthorized party can exploit it to read data from any table. This could lead to significant security breaches and unauthorized access to your content management system.
- Sensitive data exposure.
- Attackers can read any database table.
- No authentication required to exploit.
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker can exploit this vulnerability by sending a crafted HTTP request to the JSON API. This request will leverage a flaw in how the `altTable` parameter is handled, allowing the attacker to inject a SQL subquery. This subquery can then be used to extract sensitive information directly from the database.
- Target the JSON API.
- No authentication required.
- Inject SQL subquery via `altTable`.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability in Masa CMS affects unauthenticated users and allows for SQL injection, granting access to sensitive data like credentials. The ease of exploitation via a single HTTP request suggests it is a prime target for attackers looking to quickly compromise systems for data theft or further access. Given the widespread nature of content management systems, the potential attack surface is significant.
- Unauthenticated SQL injection
- Exploitable via API
- Broad impact on sensitive data
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Prioritize blocking unauthenticated API access and isolating systems if patching is delayed, as this critical SQL injection vulnerability allows unauthenticated attackers to read sensitive data from any database table. Investigate logs for evidence of exploitation.
- Update to fixed versions 7.2.10, 7.3.15, 7.4.10, or 7.5.3.
- Disable JSON API or restrict input to alphanumeric table names.
- Monitor for unauthorized data access.
