New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 5.9

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, Cisco Unified Computing System E-Series Software (UCSE) is affected by multiple remote code execution (RCE) vulnerabilities in the API subsystem due to improper boundary checks for certain user-supplied input. An unauthenticated, remote attacker can exploit these, by sending a crafted HTTP request to the API subsystem of an affected system, to execute arbitrary code with root privileges on the underlying operating system.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

Solution

Upgrade to the relevant fixed version referenced in Cisco bug IDs CSCvu21215, CSCvu21222, CSCvu22429, and CSCvu80203.
