CVE-2026-40523 Details
Description
FrontAccounting before 2.4.20 contains a SQL injection vulnerability in the Audit Trail report handler that allows authenticated attackers with SA_GLANALYTIC permission to execute arbitrary SQL queries by injecting malicious code into the PARAM_2 and PARAM_3 POST parameters. Attackers can exploit time-based blind SQL injection through SLEEP() functions that are amplified across JOIN result sets to cause denial of service by exhausting database connections, or extract arbitrary database content through UNION-based injection techniques.
A SQL injection vulnerability has been identified in FrontAccounting versions prior to 2.4.20, specifically within the Audit Trail report handler. This vulnerability allows authenticated attackers with SA_GLANALYTIC permission to execute arbitrary SQL queries by injecting malicious code into the PARAM_2 and PARAM_3 POST parameters. The issue arises from unparameterized input being directly concatenated into SQL queries, creating opportunities for SQL injection exploitation.
Users are advised to upgrade to FrontAccounting version 2.4.20 or later, where this vulnerability has been fixed. The audit trail report SQL injection vulnerability can be addressed by properly sanitizing and parameterizing user inputs before executing SQL queries.
