Cyclope Employee Surveillance Solution versions 6.x is vulnerable to a SQL injection flaw in its login mechanism. The username parameter in the auth-login POST request is not properly sanitized, allowing attackers to inject arbitrary SQL statements. This can be leveraged to write and execute a malicious PHP file on disk, resulting in remote code execution under the SYSTEM user context.
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.
