Researchers warned that unpatched versions of HPE’s Edgeline Infrastructure Manager are open to remote authentication-bypass attacks.
Hewlett Packard Business (HPE) is urging customers to patch one particular of its leading edge application administration equipment that could make it possible for an attacker to have out a remote authentication bypass attack and infiltrate a customer’s cloud infrastructure.
Rated critical, with a CVSS rating of 9.8, the bug impacts all variations of HPE’s Edgeline Infrastructure Manager (EIM) prior to edition 1.21. EIM is the company’s two-yr-outdated edge computing-management suite. People are urged to update to HPE EIM v1.22 or later to repair the bug.
Researchers at Tenable initial recognized the vulnerability (CVE-2021-29203) in late January, notifying HPE on February 1 of the critical bug. HPE introduced fixes for bug on Thursday. More than a dozen variations of program are impacted, jogging on operating units ranging from CentOS 7, Crimson Hat Business Linux, SUSE and a number of variations of Windows, according to HPE.
“A security vulnerability has been identified in the HPE Edgeline Infrastructure Supervisor, also recognised as HPE Edgeline Infrastructure Administration Computer software. The vulnerability could be remotely exploited to bypass remote authentication main to execution of arbitrary instructions, gaining privileged access, resulting in denial of assistance, and switching the configuration,” wrote HPE Product or service Security Reaction Crew in a security bulletin posted Friday.
What’s Driving HPE’s Critical Bug?
In accordance to Tenable, the distant authentication-bypass vulnerability is tied to an issue similar to how HPE handles password resets for administrator accounts.
“When [a] person logs in to the web application for the to start with time with the default password for the current Administrator account, the person is prompted to transform the password for the account. The password transform is carried out by sending a ask for to URL /redfish/v1/SessionService/ResetPassword/1. Nonetheless, after the password alter, an unauthenticated remote attacker can use the exact URL to reset the password for the Administrator account,” Tenable wrote.
All an attacker has to do next is login to the web software with the up-to-date admin password “by sending a request to URL /redfish/v1/SessionService/Sessions,” Tenable explained.
From there, researchers reported the adversary can then change the password of the “OS root account by sending a ask for to URL /redfish/v1/AccountService/Accounts/1. This will allow the attacker to SSH to the EIM host as root.”
SSH stands for Safe Shell or Protected Socket Shell and is a network protocol that is most typically employed by program directors for remote command-line requests, program logins and also for remote command execution.
Tenable posted a evidence of notion of the attack. From the time Tenable scientists introduced the bug to HPE’s attention and the deployed correct 87 times experienced elapsed, in accordance to the Tenable.
