VMware has released security updates for multiple products to
address a critical vulnerability that could be exploited to gain
access to confidential information.
Tracked as CVE-2021-22002 (CVSS score: 8.6) and
CVE-2021-22003 (CVSS score: 3.7), the flaws affect
VMware Workspace One Access (Access), VMware Identity Manager
(vIDM), VMware vRealize Automation (vRA), VMware Cloud Foundation,
and vRealize Suite Lifecycle Manager.
CVE-2021-22002 concerns an issue with how VMware Workspace One
Access and Identity Manager allow the “/cfg” web app and diagnostic
endpoints to be accessed via port 443 by tampering with a host
header, resulting in a server-side request.
“A malicious actor with network access to port 443 could tamper
with host headers to facilitate access to the /cfg web app, in
addition a malicious actor could access /cfg diagnostic endpoints
without authentication,” the company said[1]
in its advisory. Suleyman Bayir of Trendyol has been credited with
reporting the flaw.
Also addressed by VMware is an information disclosure
vulnerability impacting VMware Workspace One Access and Identity
Manager through an inadvertently exposed login interface on port
7443. An attacker with network access to port 7443 could
potentially stage a brute-force attack, which the firm noted: “may
or may not be practical based on lockout policy configuration and
password complexity for the target account.”
For customers who cannot upgrade to the latest version, VMware
is offering a workaround script[2]
for CVE-2021-22002 that can be deployed independently without
taking the vRA appliances offline. “The workaround disables the
ability to resolve the configuration page of vIDM. This endpoint is
not used in vRA 7.6 environments and will not cause any impact to
functionality,” the company said.
