Detailsinfo

A vulnerability classified as critical was found in Synology DiskStation Manager up to 7.2.0/7.2.1-69057-12/7.3.2-86009-4/7.4.1-90080-0. This vulnerability affects an unknown function of the component Auth API. The manipulation with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:
