Memory corruption vulnerabilities exist in AOS-S that are reachable by an unauthenticated adjacent attacker

Hewlett Packard Enterprise (HPE) · AOS-Switch (AOS-S)

Summary

Memory corruption flaws in HPE's AOS-Switch (AOS-S) firmware leave the switch's networking stack open to out-of-bounds memory writes, classified as improper restriction of operations within the bounds of a memory buffer. An unauthenticated attacker on an adjacent network segment, requiring no user interaction, could exploit these flaws to execute arbitrary code on the affected device.
