A vulnerability has been discovered in Cisco Smart Software Manager On-Prem which could allow for privileged read and write access to the affected system. This vulnerability can be exploited by taking advantage of a system account that has a default and static password which is not under the control of the system administrator. Successful exploitation of this vulnerability could result in the attacker gaining access to a sensitive portion of the affected system but not full administrative rights. Depending on the privileges associated with the user, an attacker could then install programs, view, change, or delete data.
We recommend the following actions be taken:
- Install the updates provided by Cisco immediately after appropriate testing.
- Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
- Remind users not to visit websites or follow links provided by unknown or untrusted sources.
- Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
- Apply the Principle of Least Privilege to all systems and services.
