| CVE-2010-5153 | 2 Avira, Microsoft | 2 Premium Security Suite, Windows Xp | 2024-07-03 | 6.2 MEDIUM | 5.3 MEDIUM |
| Race condition in Avira Premium Security Suite 10.0.0.536 on Windows XP allows local users to bypass kernel-mode hook handlers, and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack. NOTE: this issue is disputed by some third parties because it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute | |||||

| CVE-2020-12680 | 1 Avira | 1 Free Antivirus | 2024-05-17 | 2.1 LOW | 5.5 MEDIUM |
| Avira Free Antivirus through 15.0.2005.1866 allows local users to discover user credentials. The functions of the executable file Avira.PWM.NativeMessaging.exe are aimed at collecting credentials stored in Chrome, Firefox, Opera, and Edge. The executable does not verify the calling program and thus a request such as fetchChromePasswords or fetchCredentials will succeed. NOTE: some third parties have stated that this is "not a vulnerability. | |||||
| CVE-2022-4429 | 1 Avira | 1 Avira Security | 2023-11-07 | N/A | 4.4 MEDIUM |
| Avira Security for Windows contains an unquoted service path which allows attackers with local administrative privileges to cause a Denial of Service. The issue was fixed with Avira Security version 1.1.78 | |||||
| CVE-2022-4294 | 5 Avast, Avg, Avira and 2 more | 5 Antivirus, Antivirus, Avira Security and 2 more | 2023-11-07 | N/A | 7.8 HIGH |
| Norton, Avira, Avast and AVG Antivirus for Windows may be susceptible to a Privilege Escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user. | |||||
| CVE-2023-36673 | 1 Avira | 1 Phantom Vpn | 2023-10-31 | N/A | 7.3 HIGH |
| An issue was discovered in Avira Phantom VPN through 2.23.1 for macOS. The VPN client insecurely configures the operating system such that all IP traffic to the VPN server's IP address is sent in plaintext outside the VPN tunnel, even if this traffic is not generated by the VPN client, while simultaneously using plaintext DNS to look up the VPN server's IP address. This allows an adversary to trick the victim into sending traffic to arbitrary IP addresses in plaintext outside the VPN tunnel. NOTE: the tunnelcrack.mathyvanhoef.com website uses this CVE ID to refer more generally to "ServerIP attack, combined with DNS spoofing, that can leak traffic to an arbitrary IP address" rather than to only Avira Phantom VPN. | |||||
| CVE-2022-3368 | 1 Avira | 1 Avira Security | 2023-08-08 | N/A | 8.8 HIGH |
| A vulnerability within the Software Updater functionality of Avira Security for Windows allowed an attacker with write access to the filesystem, to escalate his privileges in certain scenarios. The issue was fixed with Avira Security version 1.1.72.30556. | |||||
| CVE-2023-1900 | 1 Avira | 1 Antivirus | 2023-04-29 | N/A | 5.5 MEDIUM |
| A vulnerability within the Avira network protection feature allowed an attacker with local execution rights to cause an overflow. This could corrupt the data on the heap and lead to a denial-of-service situation. Issue was fixed with Endpointprotection.exe version 1.0.2303.633 | |||||
| CVE-2022-28795 | 1 Avira | 1 Password Manager | 2022-04-20 | 4.3 MEDIUM | 6.5 MEDIUM |
| A vulnerability within the Avira Password Manager Browser Extensions provided a potential loophole where, if a user visited a page crafted by an attacker, the discovered vulnerability could trigger the Password Manager Extension to fill in the password field automatically. An attacker could then access this information via JavaScript. The issue was fixed with the browser extensions version 2.18.5 for Chrome, MS Edge, Opera, Firefox, and Safari. | |||||
| CVE-2020-8961 | 1 Avira | 1 Free Antivirus | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in Avira Free-Antivirus before 15.0.2004.1825. The Self-Protection feature does not prohibit a write operation from an external process. Thus, code injection can be used to turn off this feature. After that, one can construct an event that will modify a file at a specific location, and pass this event to the driver, thereby defeating the anti-virus functionality. | |||||
| CVE-2020-12463 | 1 Avira | 1 Software Updater | 2021-07-21 | 4.6 MEDIUM | 7.8 HIGH |
| An elevation of privilege vulnerability exists in Avira Software Updater before 2.0.6.27476 due to improperly handling file hard links. This allows local users to obtain take control of arbitrary files. | |||||

| Avira Antivirus before 5.0.2003.1821 on Windows allows privilege escalation or a denial of service via abuse of a symlink. | |||||
| CVE-2019-11396 | 2 Avira, Microsoft | 3 Free Security Suite, Software Updater, Windows | 2020-08-24 | 7.2 HIGH | 7.8 HIGH |
| An issue was discovered in Avira Free Security Suite 10. The permissive access rights on the SoftwareUpdater folder (files / folders and configuration) are incompatible with the privileged file manipulation performed by the product. Files can be created that can be used by an unprivileged user to obtain SYSTEM privileges. Arbitrary file creation can be achieved by abusing the SwuConfig.json file creation: an unprivileged user can replace these files by pseudo-symbolic links to arbitrary files. When an update occurs, a privileged service creates a file and sets its access rights, offering write access to the Everyone group in any directory. | |||||
| CVE-2016-10402 | 1 Avira | 1 Antivirus | 2020-08-05 | 9.3 HIGH | 7.8 HIGH |
| Avira Antivirus engine versions before 8.3.36.60 allow remote code execution as NT AUTHORITY\SYSTEM via a section header with a very large relative virtual address in a PE file, causing an integer overflow and heap-based buffer underflow. | |||||
| CVE-2013-4602 | 1 Avira | 10 Antivir Mailgate, Antivir Mailgate Suite, Antivir Personal and 7 more | 2020-02-18 | 7.1 HIGH | 5.5 MEDIUM |

| CVE-2017-6417 | 1 Avira | 4 Free Security Suite, Internet Security Suite, Optimization Suite and 1 more | 2019-10-03 | 7.2 HIGH | 6.7 MEDIUM |
| Code injection vulnerability in Avira Total Security Suite 15.0 (and earlier), Optimization Suite 15.0 (and earlier), Internet Security Suite 15.0 (and earlier), and Free Security Suite 15.0 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any Avira 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-2006-1274 | 1 Avira | 1 Antivir Personal | 2018-10-18 | 7.2 HIGH | N/A |
| Classic Planer in AntiVir PersonalEdition Classic 7 does not drop privileges before executing external programs, which allows local users to gain privileges via notepad.exe, which is used to display scan reports. | |||||

| The start update window in update.exe in Avira AntiVir PersonalEdition Classic 7.0 build 151 allows local users to gain system privileges via a "Shatter" style attack on the (1) IParam parameter, and the (2) PBM_GETRANGE and (3) PBM_SETRANGE messages in an unspecified progress bar. NOTE: some details are obtained from third party information. | |||||
