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."

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the K04305530 advisory.

    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)ImpactThis flaw is found in the SCP program shipped with     theopenssh-clientspackage. An attacker having the ability to SCP files to a remote server could run     arbitrary commands on the remote server by including a command as a part of the filename being copied on     the server. This command runs with the user permissions used to copy the files on the remote server. The     most serious threats from this vulnerability are to data confidentiality and integrity, as well as to     system availability.

According to its banner, the version of OpenSSH running on the remote host is potentially affected by multiple vulnerabilities.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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)

The IBM Spectrum Protect Plus running on the remote host is affected by a remote command injection vulnerability due to improper input validation in the remote function in scp.c. An unauthenticated, remote attacker can exploit this, by using backtick characters in the destination argument, to execute arbitrary commands on the system.
