F5 Networks BIG-IP : SCP vulnerability (K04305530)

high Nessus Plugin ID 179676

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 15.1.10.8 / 16.1.6.1 / 17.1.3 / 17.5.1.3. 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)

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

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

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K04305530.
