It was discovered that the Unitrends Backup (UB) before 10.1.0 libbpext.so authentication could be bypassed with a SQL injection, allowing a remote attacker to place a privilege escalation exploit on the target system and subsequently execute arbitrary commands.
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.
