Deeper analysis
A SQL injection vulnerability exists in Schneider Electric U.motion Builder software version 1.3.4. Identified as CWE-89, the flaw allows unwanted code execution when an improper set of characters is entered into the application.
The vulnerability carries a CVSS v3.1 score of 9.8 reflecting network attackability without authentication or user interaction and results in complete loss of confidentiality, integrity, and availability. An unauthenticated remote attacker can therefore achieve arbitrary code execution on the affected system.
Public disclosures reference Schneider Electric advisory SEVD-2019-071-02 along with technical details published on PacketStorm and Seclists.
