Use-after-free vulnerability in the Update Manager service in Avira Management Console allows remote attackers to execute arbitrary code via a large header. The Avira Mobile Security app before 1.5.11 for iOS sends sensitive login information in cleartext. 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.Īvira 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.

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.Ĭode 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. 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. Files can be created that can be used by an unprivileged user to obtain SYSTEM privileges. The permissive access rights on the SoftwareUpdater folder (files / folders and configuration) are incompatible with the privileged file manipulation performed by the product.
NOTE: The vendor thinks that this vulnerability is invalid because exploiting it would require at least administrator privileges and would gain only SYSTEM privileges.Īn issue was discovered in Avira Free Security Suite 10.

** DISPUTED ** Avira Software Updater before 2.4 allows a DLL side-loading attack. 1514 is prone to a local privilege escalation through the execution of kernel code from a restricted user. 1821 on Windows allows privilege escalation or a denial of service via abuse of a symlink.Īvira Free Antivirus. This allows local users to obtain take control of arbitrary files.Īvira Antivirus before. NOTE: some third parties have stated that this is "not a vulnerability."Īn elevation of privilege vulnerability exists in Avira Software Updater before 2.6 due to improperly handling file hard links. The executable does not verify the calling program and thus a request such as fetchChromePasswords or fetchCredentials will succeed. The functions of the executable file are aimed at collecting credentials stored in Chrome, Firefox, Opera, and Edge. 1866 allows local users to discover user credentials. ** DISPUTED ** Avira Free Antivirus through. 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. Thus, code injection can be used to turn off this feature. The Self-Protection feature does not prohibit a write operation from an external process. NOTE: Vendor asserts that vulnerability does not exist in product.Īn issue was discovered in Avira Free-Antivirus before. 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.

** DISPUTED ** Avira AV Engine before 8.3.54.138 allows virus-detection bypass via a crafted ISO archive.
The issue was fixed with the browser extensions version 2.18.5 for Chrome, MS Edge, Opera, Firefox, and Safari. An attacker could then access this information via JavaScript.

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.
