| Avast Premium Security Sandbox Protection Incorrect Authorization Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Avast Premium Security. 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 implementation of the sandbox feature. The issue results from incorrect authorization. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code outside the sandbox at medium integrity. . Was ZDI-CAN-20178. | ||||
| CVE-2023-42125 | 1 Avast | 1 Premium Security | 2025-08-13 | N/A |
| Avast Premium Security Sandbox Protection Link Following Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Avast Premium Security. 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 implementation of the sandbox feature. By creating a symbolic link, an attacker can abuse the service to create arbitrary namespace objects. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. . Was ZDI-CAN-20383. | ||||
| CVE-2024-13961 | 1 Avast | 1 Cleanup Premium | 2025-07-12 | 7.8 High |

| CVE-2017-8307 | 1 Avast | 1 Antivirus | 2025-04-20 | N/A |
| 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. | ||||
| CVE-2017-5567 | 1 Avast | 4 Free Antivirus, Internet Security, Premier and 1 more | 2025-04-20 | N/A |
| 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-2017-8308 | 1 Avast | 1 Antivirus | 2025-04-20 | N/A |
| 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. | ||||
| CVE-2022-4291 | 1 Avast | 1 Script Shield | 2025-04-14 | 7.7 High |
| The aswjsflt.dll library from Avast Antivirus windows contained a potentially exploitable heap corruption vulnerability that could enable an attacker to bypass the sandbox of the application it was loaded into, if applicable.
