CVE-2019-10763 in Pimcore
Summary
by MITRE
pimcore/pimcore before 6.3.0 is vulnerable to SQL Injection. An attacker with limited privileges (classes permission) can achieve a SQL injection that can lead in data leakage. The vulnerability can be exploited via 'id', 'storeId', 'pageSize' and 'tables' parameters, using a payload for trigger a time based or error based sql injection.

The vulnerability identified as CVE-2019-10763 affects pimcore/pimcore versions prior to 6.3.0 and represents a critical SQL injection flaw that undermines the integrity of database operations within the content management system. This vulnerability specifically targets applications that utilize pimcore's administrative interfaces where users possess classes permission, which typically grants access to manage data structure definitions and content types. The flaw exists in how the application processes user-supplied input parameters, failing to properly sanitize or validate data before incorporating it into database queries, thereby creating an exploitable pathway for malicious actors to manipulate backend database operations.
The technical implementation of this vulnerability occurs through multiple parameter injection points including 'id', 'storeId', 'pageSize', and 'tables' parameters within the application's query processing logic. Attackers can leverage these entry points to craft malicious payloads that trigger either time-based or error-based SQL injection techniques, allowing them to extract sensitive information from the underlying database without requiring elevated privileges. The vulnerability's exploitation requires only limited user permissions, specifically classes permission, which makes it particularly dangerous as it can be leveraged by users who should not have direct access to database operations. This characteristic aligns with CWE-89 which categorizes SQL injection vulnerabilities as those that allow attackers to manipulate database queries through untrusted input.
The operational impact of this vulnerability extends beyond simple data leakage, as it can enable attackers to perform unauthorized database operations including data modification, deletion, or extraction of confidential information. The time-based and error-based injection techniques provide attackers with different approaches to verify successful exploitation and gather information from the database without necessarily causing immediate system disruption. This type of vulnerability can lead to complete compromise of the application's data layer, potentially exposing user credentials, personal information, or business-critical data stored within the pimcore system. Organizations using vulnerable versions of pimcore may experience unauthorized access to their content management data, leading to potential regulatory compliance violations and reputational damage.
Mitigation strategies for CVE-2019-10763 primarily involve upgrading to pimcore version 6.3.0 or later, which includes proper input validation and sanitization mechanisms that prevent malicious SQL code from being executed. Organizations should also implement comprehensive input validation at all points where user-supplied data enters the application, particularly for the identified vulnerable parameters. Additionally, the principle of least privilege should be enforced by carefully reviewing and limiting user permissions, ensuring that users with classes permission do not have unnecessary access to database operations. Database access controls should be implemented to restrict direct database interactions, and regular security audits should be conducted to identify similar vulnerabilities in other application components. The ATT&CK framework categorizes this vulnerability under T1071.005 Application Layer Protocol: Web Protocols, as it exploits web application interfaces, and T1046 Network Service Scanning, when attackers attempt to identify vulnerable parameters within the application's interface.
