high Nessus Plugin ID 151319

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing a security update.

Description

According to the version of the openssh packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

 - ** DISPUTED ** scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of 'anomalous argument transfers' because that could 'stand a great chance of breaking existing workflows.'(CVE-2020-15778)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected openssh package.
