CVSS v3.1 |
| Improper access control in the Patch
Management update mechanism of TeamViewer Full Client and Host for Windows
prior to version 15.82 allows a local authenticated attacker with low
privileges to supply a signed executable through a forged IPC response and
cause it to load a malicious DLL from a user-writable temporary directory.
Successful exploitation results in arbitrary code execution with NT
AUTHORITY\SYSTEM privileges. |
| Improper authentication in the
inter-process communication (IPC) mechanism of TeamViewer Remote Management
Monitoring for Windows prior to version 26.10.1 allows a local authenticated
attacker with low privileges to impersonate the IPC broker and cause the
Monitoring service to execute arbitrary code with NT AUTHORITY\SYSTEM
privileges, resulting in local privilege escalation. |
| An improper access control vulnerability in
the IPC communication between TeamViewer Full Client or Host prior to version
15.83 and the Remote Management Monitoring component prior to version 26.10.1
allows a local authenticated attacker with low privileges to execute scripts as
SYSTEM/root. |
| A time-of-check time-of-use (TOCTOU) race condition combined with improper symbolic link handling in the privileged helper of TeamViewer Full Client and Host prior to version 15.83 for macOS allows a local attacker with low privileges to bypass installer package verification and install a malicious package. Successful exploitation can lead to local privilege escalation to root. |
| An out-of-bounds write vulnerability in the
screen-image decoder of TeamViewer Full Client for Linux and macOS prior to
version 15.83 allows a remote attacker to execute arbitrary code by supplying
crafted screen-image data during a remote-control session. The vulnerability
can also be exploited by persuading a user to open a specially crafted
TeamViewer session recording (.tvs). Missing destination bounds checking in the
decoder allows crafted screen-image data to cause an out-of-bounds write to the
image buffer. Exploitation requires user interaction. |
| An integer overflow in the remote-control
screen processing component of TeamViewer clients (Full Client, Portable and Remote
Control App) prior to version 15.83 may allow a malicious remote host to cause
a denial of service or, depending on the platform, potentially execute
arbitrary code with the privileges of the viewer process. Exploitation requires
a user to establish a remote-control session to an attacker-controlled or
compromised host. |
| A race condition in the installation
process of TeamViewer Remote Management - Patch Management for Windows prior to
version 26.9.1 allows a local authenticated attacker with low privileges to
execute arbitrary code with elevated privileges by replacing the service
executable in an insufficiently protected temporary directory during Patch
Management activation. |
| Improper access control in the installer
staging directory used by TeamViewer Full Client and Host prior to version
15.82 for Windows during installation of Advanced Asset Management allows a
local authenticated user with low privileges to execute arbitrary commands as
SYSTEM. An attacker can place a crafted installer options file that is
processed by the Advanced Asset Management installer during service activation. |
| A DLL loading vulnerability in the
TeamViewer Remote Management Monitoring installer for Windows prior to version 26.10.1
allows a local authenticated attacker with low privileges to execute arbitrary
code with elevated privileges. Exploitation requires user interaction. |
| TeamViewer Desktop through 14.7.1965 allows a bypass of remote-login access control because the same key is used for different customers' installations. It used a shared AES key for all installations since at least as far back as v7.0.43148, and used it for at least OptionsPasswordAES in the current version of the product. If an attacker were to know this key, they could decrypt protect information stored in the registry or configuration files of TeamViewer. With versions before v9.x , this allowed for attackers to decrypt the Unattended Access password to the system (which allows for remote login to the system as well as headless file browsing). The latest version still uses the same key for OptionPasswordAES but appears to have changed how the Unattended Access password is stored. While in most cases an attacker requires an existing session on a system, if the registry/configuration keys were stored off of the machine (such as in a file share or online), an attacker could then decrypt the required password to login to the system. |
| Untrusted search path vulnerability in TeamViewer 5.0.8703 and earlier allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse dwmapi.dll that is located in the same folder as a .tvs or .tvc file. |
| This vulnerability allows local attackers to disclose sensitive information on affected installations of TeamViewer. 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 TeamViewer service. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated array. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-13818. |
| This vulnerability allows remote attackers to execute arbitrary code on affected installations of TeamViewer 15.16.8.0. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of TVS files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-13697. |

The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated structure.

| TeamViewer before 14.7.48644 on Windows loads untrusted DLLs in certain situations. |
| TeamViewer Desktop for Windows before 15.8.3 does not properly quote its custom URI handlers. A malicious website could launch TeamViewer with arbitrary parameters, as demonstrated by a teamviewer10: --play URL. An attacker could force a victim to send an NTLM authentication request and either relay the request or capture the hash for offline password cracking. This affects teamviewer10, teamviewer8, teamviewerapi, tvchat1, tvcontrol1, tvfiletransfer1, tvjoinv8, tvpresent1, tvsendfile1, tvsqcustomer1, tvsqsupport1, tvvideocall1, and tvvpn1. The issue is fixed in 8.0.258861, 9.0.258860, 10.0.258873, 11.0.258870, 12.0.258869, 13.2.36220, 14.2.56676, 14.7.48350, and 15.8.3. |
| An issue was discovered in the Chat functionality of the TeamViewer desktop application 14.3.4730 on Windows. (The vendor states that it was later fixed.) Upon login, every communication is saved within Windows main memory. When a user logs out or deletes conversation history (but does not exit the application), this data is not wiped from main memory, and therefore could be read by a local user with the same or greater privileges. |
| In Omron CX-Supervisor, Versions 3.5 (12) and prior, Omron CX-Supervisor ships with Teamviewer Version 5.0.8703 QS. This version of Teamviewer is vulnerable to an obsolete function vulnerability requiring user interaction to exploit. |
| A DLL side loading vulnerability in the Windows Service in TeamViewer versions up to 11.0.133222 (fixed in 11.0.214397), 12.0.181268 (fixed in 12.0.214399), 13.2.36215 (fixed in 13.2.36216), and 14.6.4835 (fixed in 14.7.1965) on Windows could allow an attacker to perform code execution on a target system via a service restart where the DLL was previously installed with administrative privileges. Exploitation requires that an attacker be able to create a new file in the TeamViewer application directory; directory permissions restrict that by default. |
| An issue was discovered in TeamViewer 14.2.2558. Updating the product as a non-administrative user requires entering administrative credentials into the GUI. Subsequently, these credentials are processed in Teamviewer.exe, which allows any application running in the same non-administrative user context to intercept them in cleartext within process memory. By using this technique, a local attacker is able to obtain administrative credentials in order to elevate privileges. This vulnerability can be exploited by injecting code into Teamviewer.exe which intercepts calls to GetWindowTextW and logs the processed credentials. |
