| CVE-2020-10864 | 2 Avast, Microsoft | 2 Antivirus, Windows | 2021-07-21 | 5.0 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Avast Antivirus before 20. The aswTask RPC endpoint for the TaskEx library in the Avast Service (AvastSvc.exe) allows attackers to trigger a reboot via RPC from a Low Integrity process. | |||||
| CVE-2021-27241 | 1 Avast | 1 Premium Security | 2021-04-01 | 3.6 LOW | 6.1 MEDIUM |
| This vulnerability allows local attackers to delete arbitrary directories on affected installations of Avast Premium Security 20.8.2429 (Build 20.8.5653.561). An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the AvastSvc.exe module. By creating a directory junction, an attacker can abuse the service to delete a directory. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.

| CVE-2020-25289 | 1 Avast | 1 Secureline Vpn | 2020-09-17 | 2.1 LOW | 5.5 MEDIUM |
| The VPN service in AVAST SecureLine before 5.6.4982.470 allows local users to write to arbitrary files via an Object Manager symbolic link from the log directory (which has weak permissions). | |||||
| CVE-2019-18893 | 3 Avast, Avg, Video Downloader Project | 3 Secure Browser, Secure Browser, Video Downloader | 2020-01-22 | 4.3 MEDIUM | 6.1 MEDIUM |
| XSS in the Video Downloader component before 1.5 of Avast Secure Browser 77.1.1831.91 and AVG Secure Browser 77.0.1790.77 allows websites to execute their code in the context of this component. While Video Downloader is technically a browser extension, it is granted a very wide set of privileges and can for example access cookies and browsing history, spy on the user while they are surfing the web, and alter their surfing experience in almost arbitrary ways. | |||||
| CVE-2019-18653 | 2 Avast, Microsoft | 2 Antivirus, Windows | 2019-11-06 | 4.3 MEDIUM | 6.1 MEDIUM |
| A Cross Site Scripting (XSS) issue exists in Avast AntiVirus (Free, Internet Security, and Premiere Edition) 19.3.2369 build 19.3.4241.440 in the Network Notification Popup, allowing an attacker to execute JavaScript code via an SSID Name. | |||||
| CVE-2017-5567 | 1 Avast | 4 Free Antivirus, Internet Security, Premier and 1 more | 2019-10-03 | 7.2 HIGH | 6.7 MEDIUM |
| Code injection vulnerability in Avast Premier 12.3 (and earlier), Internet Security 12.3 (and earlier), Pro Antivirus 12.3 (and earlier), and Free Antivirus 12.3 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any Avast process via a "DoubleAgent" attack. One perspective on this issue is that (1) these products do not use the Protected Processes feature, and therefore an attacker can enter an arbitrary Application Verifier Provider DLL under Image File Execution Options in the registry; (2) the self-protection mechanism is intended to block all local processes (regardless of privileges) from modifying Image File Execution Options for these products; and (3) this mechanism can be bypassed by an attacker who temporarily renames Image File Execution Options during the attack. | |||||
| CVE-2019-11230 | 1 Avast | 1 Antivirus | 2019-07-24 | 3.6 LOW | 4.4 MEDIUM |
| 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. | |||||
| CVE-2016-4025 | 1 Avast | 11 Business Security, Email Server Security, Endpoint Protection and 8 more | 2016-11-04 | 2.1 LOW | 5.5 MEDIUM |
| Avast Internet Security v11.x.x, Pro Antivirus v11.x.x, Premier v11.x.x, Free Antivirus v11.x.x, Business Security v11.x.x, Endpoint Protection v8.x.x, Endpoint Protection Plus v8.x.x, Endpoint Protection Suite v8.x.x, Endpoint Protection Suite Plus v8.x.x, File Server Security v8.x.x, and Email Server Security v8.x.x allow attackers to bypass the DeepScreen feature via a DeviceIoControl call. | |||||
