VMware has issued a comprehensive patch and revised the severity stage of the NSA-claimed vulnerability to “important.”
VMware has patched a zero-working day bug that was disclosed in late November – an escalation-of-privileges flaw that impacts Workspace Just one and other platforms, for the two Windows and Linux working systems.
VMware has also revised the CVSS severity score for the bug to “important,” down from critical.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) experienced originally flagged the unpatched security vulnerability on Nov. 23, which influences 12 VMware versions throughout its Cloud Foundation, Identification Manager, vRealize Suite Lifecycle Manager and Workspace A single portfolios. It was documented to the corporation by the National Security Agency (NSA).
Tracked as CVE-2020-4006, the bug allows command injection, according to the company’s advisory.
“A malicious actor with network access to the administrative configurator on port 8443 and a legitimate password for the configurator admin account can execute commands with unrestricted privileges on the underlying working procedure,” VMware wrote in an up to date advisory on Thursday.
Though the bug was at first presented a 9.1 out of 10 on the CVSS severity scale, even more investigation confirmed that any attacker would need to have the password pointed out in the update, making it significantly more challenging to exploit proficiently. Its ranking is now 7.2, building it “important” fairly than “critical.”
“This account is inside to the impacted products and a password is established at the time of deployment,” according to the advisory. “A destructive actor have to possess this password to attempt to exploit CVE-2020-4006.”
The password would have to have to be obtained by using ways like phishing or brute forcing/credential stuffing, it additional.
When the vulnerability was disclosed in November, the business issued workarounds “for a temporary alternative to protect against exploitation of CVE-2020-4006,” with the tradeoff that configurator-managed location alterations are achievable although the workaround is in spot. Nevertheless, a entire patch is now out there.
