Hirschmann HiOS Switches Heap-based Buffer Overflow (CVE-2019-12257)

high Tenable OT Security Plugin ID 502271

Synopsis

The remote OT asset is affected by a vulnerability.

Description

DHCP packets may go past the local area network (LAN) via DHCP-relays, but are otherwise confined to the LAN.

The DHCP-client may be used by VxWorks and in the bootrom. Bootrom, using DHCP/BOOTP, is only vulnerable during the boot-process.

This vulnerability may be used to overwrite the heap, which could result in a later crash when a task requests memory from the heap. This vulnerability can result in remote code execution.

This plugin only works with Tenable.ot.
