Unauthenticated privileged code execution via stack overflow
Published Sep 15, 2026 · Updated Sep 21, 2026
Stack-based buffer overflows in HPE EdgeConnect SD-WAN Gateways allow remote attackers on an adjacent network to execute privileged code. HPE has not disclosed the affected operating-system component, attacker-controlled input, or operation that overwrites the stack buffer. Exploitation requires unspecified preconditions outside the attacker's control; success grants privileged code execution and complete gateway compromise.

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=9.4.0.0 <=9.4.8.2
- Affected versionversion=9.5.0.0 <=9.5.8.1
- Affected versionversion=9.6.0.0 <=9.6.3.1
- Affected versionversion=9.7.0.0 <=9.7.0.0
