Unauthenticated code execution via API path traversal
Published Sep 1, 2026 · Updated Sep 3, 2026
Arbitrary file write in the AOS-CX API allows remote attackers to write operating-system files and execute arbitrary code. The endpoint fails to restrict a pathname to its intended directory, so attacker-controlled path input can select files outside the permitted location. No credentials or user interaction are required, but the attacker must have adjacent-network reachability to the API; exploitation can compromise the switch operating system.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=10.10.0000 <=10.10.1180
- Affected versionversion=10.13.0000 <=10.13.1180
- Affected versionversion=10.16.0000 <=10.16.1051
- Affected versionversion=10.17.0000 <=10.17.1021
