VMware has issued fixes for 4 vulnerabilities, together with two essential 9.8-rated distant code execution bugs, in its vRealize Log Perception software program.
There aren’t any stories (but) of nation-state thugs or cybercriminals discovering and exploiting these bugs, in keeping with VMware. Nevertheless, it is a good suggestion to patch ahead of later to keep away from being affected person zero.
vRealize Log Perception is a log administration software – everybody’s favorite tas, not – and whereas it is probably not as in style as a few of the virtualization big’s different merchandise, VMware’s ubiquity throughout enterprises and governments and apply of bundling merchandise means holes in its merchandise are at all times very enticing targets for miscreants trying to make a buck and/or steal delicate info.
Working example: the state-sponsored Iranian crew that, in November, exploited the high-profile Log4j vulnerability to infiltrate an unpatched VMware Horizon server inside the US federal authorities and deployed the XMRig crypto miner.
The 2 most critical bugs in right this moment’s safety advisory embrace a listing traversal vulnerability (CVE-2022-31703) and a damaged entry management vulnerability (CVE-2022-31704). Each acquired a near-perfect 9.8 out of 10 CVSS ranking.
Whereas the 2 flaws present totally different paths for a miscreant to achieve unauthorized entry to restricted assets, the results of a profitable exploit is identical.
“An unauthenticated, malicious actor can inject recordsdata into the working system of an impacted equipment which can lead to distant code execution,” VMware warned about each essential bugs.
The third bug, CVE-2022-31710, is a deserialization vulnerability in vRealize Log Perception that would enable an unauthenticated, distant attacker to govern knowledge and trigger a denial of service assault. It is within the vital severity vary, with a 7.5 CVSS rating.
And at last, CVE-2022-31711 is an info disclosure bug that would enable an unauthenticated attacker to remotely steal delicate session and software info. It acquired a 5.3 severity ranking.

The Zero Day Initiative discovered all 4 bugs and reported them to VMware.
“We’re not conscious of any public exploit code or lively assaults utilizing this vulnerability,” Dustin Childs, head of risk consciousness at Development Micro’s ZDI, informed The Register. “Whereas we’ve no present plans to publish proof of idea for this bug, our analysis in VMware and different virtualization applied sciences continues.”
The newest safety holes come a few months after VMware disclosed three critical-rated flaws in Workspace ONE Help for Home windows – a product utilized by IT and assist desk employees to remotely take over and handle staff’ units.
These flaws have been rated 9.8 out of 10 on the CVSS scale.
A miscreant capable of attain a Workspace ONE Help deployment, both over the web or on the community, can exploit any of those three bugs to acquire administrative entry with out the necessity to authenticate. Then, the intruder or rogue insider can contact customers to supply them help that’s something however useful, equivalent to seizing management of units. ®
