Cisco Unified Computing System Software contains a vulnerability that could allow an unauthenticated, remote attacker to access sensitive information. Updates are available.
Cisco UCS Manager contains an information disclosure vulnerability. An unauthenticated, remote attacker could access technical support or local backup files that were created by a device administrator. The attacker would need to access the web interface of the Cisco UCS Manager to exploit this vulnerability.
The files that the attacker could access contain sensitive information that could lead to the complete compromise of an affected Cisco UCS platform. The attacker must know the naming convention used by the administrator as well as the date that the files were created. These files are not automatically created on a device, but occur when an administrator creates a tech support bundle file or performs an on-device configuration backup.
Cisco has confirmed the vulnerability in a security advisory and has released software updates.
The following versions of Cisco UCS are vulnerable:
Versions 2.0(1x) and prior
All 1.0(x) versions
All 1.1(x) versions
All 1.2(x) versions
All 1.3(x) versions
All 1.4(x) versions
To exploit this vulnerability, an attacker must know the naming convention used by the administrator as well as the date that the sensitive files were created on a targeted device.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
An unauthenticated, remote attacker could exploit this vulnerability to access technical support or local backup files that were created by an administrator on an affected device. Successful exploitation could result in a complete system compromise.
The vulnerability is due to insufficient security restrictions imposed by the web interface of the affected software.
An unauthenticated, remote attacker that can access the web interface on a targeted system could exploit this vulnerability to gain unauthorized access to sensitive information. If successful, the attacker could use this information to completely compromise the targeted system.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to have network access.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
Administrators are advised to monitor affected systems.
