Multiple SQL injection vulnerabilities in TekRADIUS 3.0 allow context-dependent attackers to execute arbitrary SQL commands via (1) the GUI client, as demonstrated by input to the Browse Users text box in the Users tab; or (2) the command-line client, as demonstrated by a certain trcli -r command.
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.
