CVE-2023-28438: 
PHP vulnerability analysis and mitigation

Pimcore, an open source data and experience management platform, disclosed a vulnerability (CVE-2023-28438) affecting versions prior to 10.5.19. The vulnerability stems from improper quoting of filters and path traversal in Custom Reports functionality, where users with 'report' permission could execute arbitrary SQL queries through GET method endpoints lacking CSRF protection (GitHub Advisory).

The vulnerability received a CVSS v3.1 base score of 8.0 HIGH (NIST) and 6.2 MEDIUM (GitHub). The technical nature of the vulnerability involves SQL injection and path traversal issues in the Custom Reports feature. The vulnerability is classified under CWE-89 (SQL Injection) and allows attackers to inject arbitrary queries by manipulating users to click on malicious links (NVD).

The vulnerability's impact is significant as it allows attackers to execute arbitrary PHP code on the server with webserver permissions. The path traversal aspect enables creation of arbitrary files and appending data to existing files. When combined with SQL injection capabilities, attackers can control exported data and potentially upload webshells (GitHub Advisory).

Users are advised to upgrade to Pimcore version 10.5.19 which contains the security patch. Alternatively, manual patches can be applied using two specific commits. The patches address the improper quoting of filters and path traversal issues (GitHub Advisory).
