Technical details

A CSV injection vulnerability (CWE-1236) exists in the UI of Dell ECS (3.8.1.0-3.8.1.7) and Dell ObjectScale (prior to 4.3.0.0). The application fails to properly neutralize formula elements (such as =, +, -, or @) when generating CSV files. An unauthenticated remote attacker can exploit this by injecting malicious formulas into fields that are later exported to a CSV file. When a victim downloads and opens this file in a spreadsheet application like Microsoft Excel, the formula may execute, leading to remote code execution on the victim's machine. The attack requires user interaction and has a high complexity due to the reliance on the victim's spreadsheet software configuration.

Affected products

Dell ECS 3.8.1.0 - 3.8.1.7
Dell ObjectScale Prior to 4.3.0.0
