Ivan Fratric from Google | Zoom got Help in Crisis

Latest Bugs Found in February

1	2	3	4
CVE-2022-22784	CVE-2022-22785	CVE-2022-22786	CVE-2022-22787
(CVSS score: 8.1)	(CVSS score: 5.9)	(CVSS score: 7.5)	(CVSS score: 5.9)
Improper XML praising	Improperly constrained sessions cookies	Upgrade package downgrade for Windows	Insufficient hostname validation during server switch

The Zoom Chat function is built on XMPP. This can cause successful exploitation that could enable an attacker to:

Force a vulnerable client to masquerade as a Zoom User
Connect to a malicious server
Download a rogue update that can cause an Arbitrary Code Execution stemming from a downgrade attack.

According to Ivan Fratrick…..

“It was a Sequence Attack, a case of XMPP Stanza Smuggling. Plus, the attacker could steal the message if it was coming from the side of another user. Also, the Cybercriminal can send a Control Message just like the server would act to it”.

Zoom Conference Issue was:

The issues took advantage of parsing inconsistencies to “smuggle in” from inconsistent XMPP verses that occurred between XML parsers in Zoom’s client and server.

Big Trouble for Zoom Conference App Users

This whole chain can hijack the Software Updating System. Also, it can drive the user to the server that is connected with the attacker which serves an old and uncredible version of the Zoom App.

The downgrade attack singles out the Windows version of the app, CVE-2022-22784/ 85/ 87 that would impact Android/ iOS/ Linux/ macOS/ Windows.

Zoom Conference Issues Resolve

The patches arrive less than a month after Zoom addressed two high-severity flaws.

CVE-2022-22782
CVE-2022-22783

These could lead to a local privilege escalation and expose the memory contents in its On-Premise Meeting Services. In addition to this, it also fixed another case of a downgrade attack which was CVE-2022-22781 in Zoom’s MacOS App.

Note: recommendation is to update the version of their Zoom App, so that they wouldn’t cross paths with potential threats arising out of active exploitation flaws.
