Hirschmann HiOS Switches Classic Buffer Overflow (CVE-2019-12261)

critical Tenable OT Security Plugin ID 502270

Synopsis

The remote OT asset is affected by a vulnerability.

Description

The impact of this vulnerability is a buffer overflow of up to a full TCP receive-window (by default, 10k-64k depending on version). The buffer overflow happens in the task calling recv()/recvfrom()/recvmsg().

Applications that pass a buffer equal to or larger than a full TCP-window are not susceptible to this attack. Applications passing a stack-allocated variable as a buffer are the easiest to exploit.

The most likely outcome is a crash of the application reading from the affected socket, which could result in remote code execution.

This plugin only works with Tenable.ot.
