frontaccounting是frontaccounting团队开源的一款会计管理软件。 FrontAccounting 2.4.20之前版本存在SQL注入漏洞，该漏洞源于get_gl_transactions()函数中filter_type参数直接被拼接到SQL IN()子句中而未进行参数化，导致SQL注入，具有SA_GLANALYTIC权限的攻击者可以通过提供闭括号后跟恶意条件来注入任意SQL，通过基于布尔的盲SQL注入和可靠的响应大小差异提取敏感日记账条目数据。

Vulnerability Title
FrontAccounting < 2.4.20 SQL Injection via get_gl_transactions()
Source: CVE Program / CVE List V5
Vulnerability Description
FrontAccounting before 2.4.20 contains a SQL injection vulnerability in the get_gl_transactions() function where the filter_type parameter is concatenated directly into a SQL IN() clause without parameterization. Attackers with SA_GLANALYTIC permission can inject arbitrary SQL by supplying a closing parenthesis followed by malicious conditions to extract sensitive journal entry data through boolean-based blind SQL injection with reliable response size differentials.
