Cisco Data Center Network Manager Multiple Directory Traversal Vulnerabilities

Risk

High

Date Discovered

January 2, 2020

Description

Cisco Data Center Network Manager is prone to a multiple directory-traversal vulnerabilities because it fails to sufficiently sanitize user-supplied input. Remote attackers may use a specially crafted request with directory-traversal sequences ('../') to retrieve arbitrary files from the affected system in the context of the application. Information obtained could aid in further attacks. These issues are being tracked by Cisco Bug IDs CSCvq85957, CSCvq85972, CSCvq85998, CSCvq89422, CSCvq89834, CSCvq89841, CSCvq89878, CSCvq89895, CS,vr05463, CSCvr17970, CSCvr44896, CSCvr46508, CSCvr79240, CSCvs16318, CSCvs16341, CSCvs16350.

Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.

Run all software as a nonprivileged user with minimal access rights.
To limit the consequences of a successful exploit, run server processes within a restricted environment using facilities such as chroot or jail.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review its logs regularly.

Updates are available. Please see the references or vendor advisory for more information.
