A critical vulnerability recently patched in the Cisco Video Surveillance Manager (VSM) could allow an unauthenticated attacker to log in as root.
The security flaw, Cisco revealed on Friday, impacts only the VSM software running on certain Connected Safety and Security Unified Computing System (UCS) platforms. The issue, the company says, resides in the presence of default, static credentials for the root account.
The credentials for the account are undocumented and only impact certain systems, the company underlines. An attacker exploiting the vulnerability could log in to the affected systems and execute arbitrary commands as the root user.
The bug, Cisco reveals, impacts VSM Software releases 7.10, 7.11, and 7.11.1. The issue, however, only manifests if the software was preinstalled by Cisco and only impacts the CPS-UCSM4-1RU-K9, CPS-UCSM4-2RU-K9, KIN-UCSM5-1RU-K9, and KIN-UCSM5-2RU-K9 Connected Safety and Security UCS platforms.
“This vulnerability exists because the root account of the affected software was not disabled before Cisco installed the software on the vulnerable platforms, and default, static user credentials exist for the account. The user credentials are not documented publicly,” Cisco notes in an advisory.
VSM Software Releases 7.9 and earlier are not impacted by the bug. VSM releases 7.10, 7.11, and 7.11.1 running on CPS-UCSM4-1RU-K9 and CPS-UCSM4-1RU-K9 platforms aren’t impacted either if they were installed as upgrades to a pre-installed release 7.9. VSM on the VMware ESXi platform isn’t impacted either.
There are no workarounds for this vulnerability and affected users are advised to upgrade to VSM Release 7.12 to patch it. Those who do not want to upgrade should contact the Cisco TAC for further assistance.
“The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability,” Cisco also notes.
