Description

Fleet is open source device management software. Prior to 4.81.0, a second-order SQL injection vulnerability in Fleet's Apple MDM profile delivery pipeline could allow an attacker with a valid MDM enrollment certificate to exfiltrate or modify the contents of the Fleet database, including user credentials, API tokens, and device enrollment secrets. Version 4.81.0 patches the issue.

• 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.
