CVE-2018-0279: A vulnerability in the Secure Copy Protocol (SCP) server of Cisco Enterprise NFV Infrastructure Software (N...

A vulnerability in the Secure Copy Protocol (SCP) server of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, remote attacker to access the shell of the underlying Linux operating system on the affected device. The vulnerability is due to improper input validation of command arguments. An attacker could exploit this vulnerability by using crafted arguments when opening a connection to the affected device. An exploit could allow the attacker to gain shell access with a non-root user account to the underlying Linux operating system on the affected device. Due to the system design, access to the Linux shell could allow execution of additional attacks that may have a significant impact on the affected system. This vulnerability affects Cisco devices that are running release 3.7.1, 3.6.3, or earlier releases of Cisco Enterprise NFV Infrastructure Software (NFVIS) when access to the SCP server is allowed on the affected device. Cisco NFVIS Releases 3.5.x and 3.6.x do allow access to the SCP server by default, while Cisco NFVIS Release 3.7.1 does not. Cisco Bug IDs: CSCvh25026.

Security readout for executives and security teams

Cisco NFVIS could let an authenticated remote user reach the underlying Linux shell through the SCP server. The access is non-root, but Cisco warns the system design could enable further attacks with significant impact. Exposure depends on running affected NFVIS releases and allowing SCP access. Most relevant exposure is Cisco NFVIS 3.7.1, 3.6.3, or earlier with SCP access allowed. Cisco NFVIS 3.5.x and 3.6.x allow SCP server access by default; 3.7.1 does not, according to the source bundle. Treat as high priority for NFV infrastructure because shell access on virtualization infrastructure can affect service availability and trust boundaries. Urgency is highest where SCP is exposed beyond tightly controlled administrator networks. Mitigation focus: Review Cisco advisory cisco-sa-20180516-nfvis for fixed releases or official workarounds.; Disable SCP access where it is not operationally required.; Restrict SCP access to trusted administration networks and accounts..
