CVE-2010-5153 2 Avira, Microsoft 2 Premium Security Suite, Windows Xp 2024-08-07 6.2 MEDIUM 5.3 MEDIUM
** DISPUTED ** 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-2019-17449 1 Avira 1 Software Updater 2024-08-05 4.6 MEDIUM 6.7 MEDIUM
** DISPUTED ** Avira Software Updater before 2.0.6.21094 allows a DLL side-loading attack. NOTE: The vendor thinks that this vulnerability is invalid because exploiting it would require at least administrator privileges and would gain only SYSTEM privileges.
CVE-2020-12680 1 Avira 1 Free Antivirus 2024-08-04 2.1 LOW 5.5 MEDIUM
** DISPUTED ** 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-2020-9320 1 Avira 8 Anti-malware Sdk, Antivirus Server, Avira Antivirus For Endpoint and 5 more 2024-08-04 4.3 MEDIUM 5.5 MEDIUM
** DISPUTED ** Avira AV Engine before 8.3.54.138 allows virus-detection bypass via a crafted ISO archive. This affects versions before 8.3.54.138 of Antivirus for Endpoint, Antivirus for Small Business, Exchange Security (Gateway), Internet Security Suite for Windows, Prime, Free Security Suite for Windows, and Cross Platform Anti-malware SDK. NOTE: Vendor asserts that vulnerability does not exist in product.
CVE-2023-36673 1 Avira 1 Phantom Vpn 2024-02-05 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-2023-1900 1 Avira 1 Antivirus 2024-02-04 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-2022-3368 1 Avira 1 Avira Security 2024-02-04 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-2022-28795 1 Avira 1 Password Manager 2024-02-04 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-2020-12254 1 Avira 1 Antivirus 2024-02-04 4.6 MEDIUM 7.8 HIGH
Avira Antivirus before 5.0.2003.1821 on Windows allows privilege escalation or a denial of service via abuse of a symlink.
CVE-2020-12463 1 Avira 1 Software Updater 2024-02-04 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.
CVE-2020-8961 1 Avira 1 Free Antivirus 2024-02-04 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-2019-18568 2 Avira, Microsoft 2 Free Antivirus, Windows 2024-02-04 7.2 HIGH 8.8 HIGH
Avira Free Antivirus 15.0.1907.1514 is prone to a local privilege escalation through the execution of kernel code from a restricted user.
CVE-2013-4602 1 Avira 10 Antivir Mailgate, Antivir Mailgate Suite, Antivir Personal and 7 more 2024-02-04 7.1 HIGH 5.5 MEDIUM
A Denial of Service (infinite loop) vulnerability exists in Avira AntiVir Engine before 8.2.12.58 via an unspecified function in the PDF Scanner Engine.
CVE-2019-11396 2 Avira, Microsoft 3 Free Security Suite, Software Updater, Windows 2024-02-04 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-2015-7732 1 Avira 1 Avira Mobile Security 2024-02-04 5.0 MEDIUM 7.5 HIGH
The Avira Mobile Security app before 1.5.11 for iOS sends sensitive login information in cleartext.
CVE-2016-10402 1 Avira 1 Antivirus 2024-02-04 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-2017-6417 1 Avira 4 Free Security Suite, Internet Security Suite, Optimization Suite and 1 more 2024-02-04 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-2015-7303 1 Avira 1 Management Console 2024-02-04 10.0 HIGH N/A
Use-after-free vulnerability in the Update Manager service in Avira Management Console allows remote attackers to execute arbitrary code via a large header.
CVE-2014-5576 1 Avira 1 Avira Secure Backup 2024-02-04 5.4 MEDIUM N/A
The Avira Secure Backup (aka com.avira.avirabackup) application 1.2.3 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
CVE-2012-1425 14 Antiy, Avira, Cat and 11 more 16 Avl Sdk, Antivir, Quick Heal and 13 more 2024-02-04 4.3 MEDIUM N/A
The TAR file parser in Avira AntiVir 7.11.1.163, Antiy Labs AVL SDK 2.0.3.7, Quick Heal (aka Cat QuickHeal) 11.00, Emsisoft Anti-Malware 5.1.0.1, Fortinet Antivirus 4.2.254.0, Ikarus Virus Utilities T3 Command Line Scanner 1.1.97.0, Jiangmin Antivirus 13.0.900, Kaspersky Anti-Virus 7.0.0.125, McAfee Anti-Virus Scanning Engine 5.400.0.1158, McAfee Gateway (formerly Webwasher) 2010.1C, NOD32 Antivirus 5795, Norman Antivirus 6.06.12, PC Tools AntiVirus 7.0.3.5, AVEngine 20101.3.0.103 in Symantec Endpoint Protection 11, Trend Micro AntiVirus 9.120.0.1004, and Trend Micro HouseCall 9.120.0.1004 allows remote attackers to bypass malware detection via a POSIX TAR file with an initial \50\4B\03\04 character sequence. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different TAR parser implementations.
