Description

Part-DB 0.4 contains an authentication bypass vulnerability that allows unauthenticated attackers to login by injecting SQL syntax into authentication parameters. Attackers can submit a single quote followed by 'or' in the login form to bypass credential validation and gain unauthorized access to the application.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')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.
