CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

CVE-2021-47711 is a high-severity SQL injection vulnerability in Kentico Xperience (up to version 13.0.52) that allows authenticated editors to inject malicious SQL queries via parameters in online marketing macro methods. This happens because the input validation for these macro method parameters is insufficient, enabling attackers to execute unauthorized database commands. [1]

Impact Analysis

This vulnerability can lead to unauthorized access to the database and potential manipulation of data. An attacker with low privileges but authenticated as an editor can exploit this flaw to compromise the confidentiality and integrity of the database, possibly leading to data breaches or corruption. [1]

Detection Guidance

Detection involves monitoring for unusual or unauthorized SQL queries originating from authenticated editors using online marketing macro methods in Kentico Xperience. Since the vulnerability exploits macro method parameters, inspecting logs for suspicious macro parameter usage or unexpected database queries can help. Specific commands are not provided in the resources. [1]

Mitigation Strategies

Immediate mitigation steps include applying the hotfixes provided by the Kentico Security Team for versions up to and including 13.0.52. Additionally, restrict editor privileges to the minimum necessary and monitor macro method usage closely to prevent exploitation. [1]
