#	CVE ID	CWE ID	# of Exploits	Vulnerability Type(s)	Publish Date	Update Date	Score	Gained Access Level	Access	Complexity	Authentication	Conf.	Integ.	Avail.
1	CVE-2020-11877	330			2020-04-17	2022-05-03	5.0	None	Remote	Low	Not required	Partial	None	None
DISPUTED airhost.exe in Zoom Client for Meetings 4.6.11 uses 3423423432325249 as the Initialization Vector (IV) for AES-256 CBC encryption. NOTE: the vendor states that this IV is used only within unreachable code.
2	CVE-2020-11876	327			2020-04-17	2022-05-03	5.0	None	Remote	Low	Not required	Partial	None	None
DISPUTED airhost.exe in Zoom Client for Meetings 4.6.11 uses the SHA-256 hash of 0123425234234fsdfsdr3242 for initialization of an OpenSSL EVP AES-256 CBC context. NOTE: the vendor states that this initialization only occurs within unreachable code.
3	CVE-2020-11500	327			2020-04-03	2020-04-07	5.0	None	Remote	Low	Not required	Partial	None	None
Zoom Client for Meetings through 4.6.9 uses the ECB mode of AES for video and audio encryption. Within a meeting, all participants use a single 128-bit key.
4	CVE-2020-11470	862			2020-04-01	2021-07-21	2.1	None	Local	Low	Not required	Partial	None	None
Zoom Client for Meetings through 4.6.8 on macOS has the disable-library-validation entitlement, which allows a local process (with the user's privileges) to obtain unprompted microphone and camera access by loading a crafted library and thereby inheriting Zoom Client's microphone and camera access.
5	CVE-2020-11469	552			2020-04-01	2022-07-12	7.2	None	Local	Low	Not required	Complete	Complete	Complete
Zoom Client for Meetings through 4.6.8 on macOS copies runwithroot to a user-writable temporary directory during installation, which allows a local process (with the user's privileges) to obtain root access by replacing runwithroot.
6	CVE-2020-11443	732			2020-05-04	2021-07-21	8.5	None	Remote	Low	???	None	Complete	Complete
The Zoom IT installer for Windows (ZoomInstallerFull.msi) prior to version 4.6.10 deletes files located in %APPDATA%\Zoom before installing an updated version of the client. Standard users are able to write to this directory, and can write links to other directories on the machine. As the installer runs with SYSTEM privileges and follows these links, a user can cause the installer to delete files that otherwise cannot be deleted by the user.
7	CVE-2020-9767	427			2020-08-14	2020-08-21	7.2	None	Local	Low	Not required	Complete	Complete	Complete
A vulnerability related to Dynamic-link Library (“DLL”) loading in the Zoom Sharing Service would allow an attacker who had local access to a machine on which the service was running with elevated privileges to elevate their system privileges as well through use of a malicious DLL. Zoom addressed this issue, which only applies to Windows users, in the 5.0.4 client release.
8	CVE-2020-6110	22		Exec Code Dir. Trav.	2020-06-08	2022-05-12	6.8	None	Remote	Medium	Not required	Partial	Partial	Partial
An exploitable partial path traversal vulnerability exists in the way Zoom Client version 4.6.10 processes messages including shared code snippets. A specially crafted chat message can cause an arbitrary binary planting which could be abused to achieve arbitrary code execution. An attacker needs to send a specially crafted message to a target user or a group to trigger this vulnerability. For the most severe effect, target user interaction is required.
9	CVE-2020-6109	22		Exec Code Dir. Trav.	2020-06-08	2022-05-12	7.5	None	Remote	Low	Not required	Partial	Partial	Partial
An exploitable path traversal vulnerability exists in the Zoom client, version 4.6.10 processes messages including animated GIFs. A specially crafted chat message can cause an arbitrary file write, which could potentially be abused to achieve arbitrary code execution. An attacker needs to send a specially crafted message to a target user or a group to exploit this vulnerability.
