CVE-2026-35157 · Severity: medium · CVSS 5.8 · Published 2026-05-11

Dell ECS and ObjectScale, which are enterprise storage solutions, are vulnerable to a security flaw in their management interface. An attacker could trick a user into downloading and opening a specially crafted file from the system, which could then execute malicious commands on the user's computer. This could lead to unauthorized access or the compromise of the user's workstation.

Technologies: [Dell ECS](https://junglewise.ai/threats/technologies/ecs), [Dell ObjectScale](https://junglewise.ai/threats/technologies/objectscale). Vendors: [Dell](https://junglewise.ai/threats/vendors/dell).

## 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
