Privilege escalation via second-order report SQL injection
Published Sep 14, 2023 · Updated Sep 25, 2024
SQL injection in Vtiger CRM 7.5.0 allows remote authenticated users to disclose sensitive database fields through crafted reports. ReportRun.php validates only the permitted field name at index 3, then trusts attacker-controlled table and column values at indexes 0 and 1. Any CRM user who can create a report can retrieve fields outside that user's permissions, including administrator password hashes and API access keys.
