#	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-2021-45339	269		+Priv Bypass	2021-12-27	2022-01-10	7.2	None	Local	Low	Not required	Complete	Complete	Complete
Privilege escalation vulnerability in Avast Antivirus prior to 20.4 allows a local user to gain elevated privileges by "hollowing" trusted process which could lead to the bypassing of Avast self-defense.
2	CVE-2021-45338	269		+Priv	2021-12-27	2022-01-07	7.2	None	Local	Low	Not required	Complete	Complete	Complete
Multiple privilege escalation vulnerabilities in Avast Antivirus prior to 20.4 allow a local user to gain elevated privileges by calling unnecessarily powerful internal methods of the main antivirus service which could lead to the (1) arbitrary file delete, (2) write and (3) reset security.
3	CVE-2021-45337	269		+Priv	2021-12-27	2022-01-07	7.2	None	Local	Low	Not required	Complete	Complete	Complete
Privilege escalation vulnerability in the Self-Defense driver of Avast Antivirus prior to 20.8 allows a local user with SYSTEM privileges to gain elevated privileges by "hollowing" process wsc_proxy.exe which could lead to acquire antimalware (AM-PPL) protection.
4	CVE-2021-45336	269		+Priv	2021-12-27	2022-01-07	7.2	None	Local	Low	Not required	Complete	Complete	Complete
Privilege escalation vulnerability in the Sandbox component of Avast Antivirus prior to 20.4 allows a local sandboxed code to gain elevated privileges by using system IPC interfaces which could lead to exit the sandbox and acquire SYSTEM privileges.
5	CVE-2021-45335	276			2021-12-27	2022-01-07	7.2	None	Local	Low	Not required	Complete	Complete	Complete
Sandbox component in Avast Antivirus prior to 20.4 has an insecure permission which could be abused by local user to control the outcome of scans, and therefore evade detection or delete arbitrary system files.
6	CVE-2019-17093	426		Bypass	2019-10-23	2021-07-21	4.4	None	Local	Medium	Not required	Partial	Partial	Partial
An issue was discovered in Avast antivirus before 19.8 and AVG antivirus before 19.8. A DLL Preloading vulnerability allows an attacker to implant %WINDIR%\system32\wbemcomn.dll, which is loaded into a protected-light process (PPL) and might bypass some of the self-defense mechanisms. This affects all components that use WMI, e.g., AVGSvc.exe 19.6.4546.0 and TuneupSmartScan.dll 19.1.884.0.
7	CVE-2019-11230	59			2019-07-18	2019-07-24	3.6	None	Local	Low	Not required	None	Partial	Partial
In Avast Antivirus before 19.4, a local administrator can trick the product into renaming arbitrary files by replacing the Logs\Update.log file with a symlink. The next time the product attempts to write to the log file, the target of the symlink is renamed. This defect can be exploited to rename a critical product file (e.g., AvastSvc.exe), causing the product to fail to start on the next system restart.
8	CVE-2017-8308	269		Bypass	2017-04-27	2019-10-03	5.0	None	Remote	Low	Not required	None	Partial	None
In Avast Antivirus before v17, an unprivileged user (and thus malware or a virus) can mark an arbitrary process as Trusted from the perspective of the Avast product. This bypasses the Self-Defense feature of the product, opening a door to subsequent attack on many of its components.
9	CVE-2017-8307			DoS	2017-04-27	2019-10-03	7.5	None	Remote	Low	Not required	Partial	Partial	Partial
In Avast Antivirus before v17, using the LPC interface API exposed by the AvastSVC.exe Windows service, it is possible to launch predefined binaries, or replace or delete arbitrary files. This vulnerability is exploitable by any unprivileged user when Avast Self-Defense is disabled. It is also exploitable in conjunction with CVE-2017-8308 when Avast Self-Defense is enabled. The vulnerability allows for Denial of Service attacks and hiding traces of a possible attack.
