Version Summary: Cisco Application Policy Infrastructure Controller contains a
vulnerability that could allow an authenticated, remote attacker to gain
unauthorized access to information stored on a targeted system. Updates are
available.
Description
A vulnerability in the role-based access control (RBAC) of the Cisco
Application Policy Infrastructure Controller (Cisco APIC) could allow an
authenticated, remote attacker to have read access to certain information
stored in the affected system.
The vulnerability is due to improper handling of RBAC for health scoring. An
attacker could exploit this vulnerability to gain access to information on the
affected system.
Cisco has confirmed the vulnerability and released software updates.
Warning Indicators
At the time this alert was first published, Cisco APIC implemented on Cisco
Nexus 9000 Series Switches releases 1.0(1.110a) and 1.0(1e) were vulnerable.
Later releases of Cisco Nexus 9000 Series Switches may also be vulnerable.
IntelliShield Analysis
To exploit this vulnerability, an attacker must authenticate to the targeted
system. This access requirement reduces the likelihood of a successful
exploit.
Cisco indicates through the CVSS score that functional exploit code exists;
however, the code is not known to be publicly available.
Vendor Announcements
Cisco has released bug ID CSCuq77485 for registered users, which contains
additional details and an up-to-date list of affected product versions.
Impact
An authenticated, remote attacker could exploit this vulnerability to gain
unauthorized access to sensitive information on an affected system. A
successful exploit could be used to conduct further attacks.
Technical Information
The vulnerability is due to improper handling of RBAC protection for health
scoring on an affected system.
An attacker could exploit this vulnerability to gain access to information on
a targeted system. A successful exploit could be leveraged to conduct further
attacks.
Safeguards
