CVE-2020-11853
Overview
This vulnerability is an arbitrary code execution flaw caused by improper input validation in multiple Micro Focus products, including Operation Bridge Manager. The root cause lies in insecure handling of user-supplied input within critical components responsible for command execution or processing, allowing crafted input to be executed as code. Affected components span several versions of Operation Bridge Manager and related Micro Focus management suites.
Vulnerability Description
Arbitrary code execution vulnerability affecting multiple Micro Focus products. 1.) Operation Bridge Manager affecting version: 2020.05, 2019.11, 2019.05, 2018.11, 2018.05, versions 10.6x and 10.1x and older versions. 2.) Application Performance Management affecting versions : 9.51, 9.50 and 9.40 with uCMDB 10.33 CUP 3 3.) Data Center Automation affected version 2019.11 4.) Operations Bridge (containerized) affecting versions: 2019.11, 2019.08, 2019.05, 2018.11, 2018.08, 2018.05, 2018.02, 2017.11 5.) Universal CMDB affecting version: 2020.05, 2019.11, 2019.05, 2019.02, 2018.11, 2018.08, 2018.05, 11, 10.33, 10.32, 10.31, 10.30 6.) Hybrid Cloud Management affecting version 2020.05 7.) Service Management Automation affecting version 2020.5 and 2020.02. The vulnerability could allow to execute arbitrary code.
Impact
An attacker with network access and low-level privileges can execute arbitrary code remotely on affected systems without user interaction, leveraging this vulnerability to gain unauthorized control. This enables compromise of confidentiality, integrity, and availability of the affected Micro Focus management platforms. The CVSS vector indicates network attack vector, low attack complexity, and requires privileges but no user interaction, facilitating lateral movement and persistent foothold within enterprise environments.
Solution
Micro Focus has released security advisories KM03747658, KM03747657, and KM03747854 detailing patches and updates for affected products. Users should apply the corresponding patches for Operation Bridge Manager versions 2020.05, 2019.11, and earlier, as well as for Application Performance Management, Universal CMDB, and other impacted suites. Detailed patch instructions and version-specific fixes are available at https://softwaresupport.softwaregrp.com/doc/KM03747658. Adherence to these updates is critical to mitigate the vulnerability.
