Vulnerability Details : CVE-2021-23837
Potential exploit
An issue was discovered in flatCore before 2.0.0 build 139. A time-based blind SQL injection was identified in the selected_folder HTTP request body parameter for the acp interface. The affected parameter (which retrieves the file contents of the specified folder) was found to be accepting malicious user input without proper sanitization, thus leading to SQL injection. Database related information can be successfully retrieved.

CWE ids for CVE-2021-23837
-
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.Assigned by: nvd@nist.gov (Primary)
