An issue was discovered in Shopware B2B-Suite through 4.4.1. The sort-by parameter of the search functionality of b2border and b2borderlist allows SQL injection. Possible techniques are boolean-based blind, time-based blind, and potentially stacked queries. The vulnerability allows a remote authenticated attacker to dump the underlying database.
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.
