CVSS v3.1 |
| TeamViewer Full Client and Host for Linux and macOS prior version 15.82 contain a heap-based buffer overflow vulnerability in the processing of .tvs session recording files. A size mismatch during decompression of recorded session data can result in out-of-bounds heap writes. By convincing a user to open a specially crafted session recording through the "Play or convert recorded session…" feature, an attacker may achieve arbitrary code execution with the privileges of the current user |
| TeamViewer Full Client and Host for Linux prior version 15.82 contains an improper path validation vulnerability in the Cloud Session Recording (CSR) functionality. By exploiting a race condition during path validation and subsequent file access, a local authenticated attacker may cause privileged file operations in unintended locations on the affected system. |
| An improper access control vulnerability in TeamViewer Full Client, Host, and related affected modules on Windows, Linux, and macOS allows an authenticated remote attacker to bypass user-configured permission settings during session establishment. By modifying access control parameters for restricted features, an attacker can perform actions that were explicitly denied by the victim's configuration. This may result in unauthorized actions and potentially lead to remote code execution on the target system. |
| Improper
neutralization of path traversal sequences in TeamViewer Desktop Clients prior
Version 15.81.5 allows an authenticated remote session participant to write files
to unintended locations on the local file system via file transfer or virtual
file clipboard mechanisms. An attacker can leverage this behavior to achieve
arbitrary file write and potentially execute code with the privileges of the
affected user. |
| A command injection vulnerability in TeamViewer Full
Client and Host for Linux prior to version 15.81.5 allows a remote attacker to
execute arbitrary commands in the context of the current user via a specially
crafted URL sent through the out-of-session chat feature. Exploitation requires
user interaction by clicking the malicious link. |
| TeamViewer Full Client and Host for macOS before version 15.80 contain a business logic error that can allow an authenticated attacker to bypass a configured 2FA for Connections approval flow via Unattended Access and establish a remote connection to an affected macOS host. |
| A broken access
control vulnerability exists in the TeamViewer DEX Platform (On‑Premises) prior version 9.2. Certain backend API endpoints do not
correctly enforce authorization checks, allowing an authenticated user with low
privileges to perform actions and access resources intended only for higher‑privileged roles. An attacker with
low‑privileged credentials may exploit
this to gain unauthorized access to administrative or sensitive functionality. |
| A command
injection vulnerability was discovered in TeamViewer DEX Platform On-Premises
(former 1E DEX Platform On-Premises) prior to version 9.2. Improper input validation allows
authenticated users with at least questioner privileges to inject commands in specific
instructions. Exploitation could lead to execution of elevated commands on
devices connected to the platform. |
| A vulnerability in TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to cause the NomadBranch.exe process to terminate via crafted requests. This can result in a denial-of-service condition of the Content Distribution Service. |
| A missing validation of a user-controlled value in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an adjacent network attacker to tamper with log timestamps via crafted UDP Sync command. This could result in forged or nonsensical datetime prefixes and compromising log integrity and forensic correlation. |
| Improper Link Resolution Before File Access (invoked by 1E‑Explorer‑TachyonCore‑DeleteFileByPath instruction) in TeamViewer DEX - 1E Client before version 26.1 on Windows allows a low‑privileged local attacker to delete protected system files via a crafted RPC control junction or symlink that is followed when the delete instruction executes. |
| A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Nomad-RunPkgStatusRequest instruction. Improper input validation allows authenticated attackers with actioner privilege to run elevated arbitrary commands on connected hosts via malicious commands injected into the instruction’s input field. Users of 1E Client version 24.5 or higher are not affected. |
| A vulnerability in TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to cause normally encrypted UDP traffic to be sent in cleartext. This can result in disclosure of sensitive information. |
| A vulnerability in TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to inject, tamper with, or forge log entries in \Nomad Branch.log via crafted data sent to the UDP network handler. This can impact log integrity and nonrepudiation. |
| An integer underflow in the UDP command handler of the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an adjacent network attacker to trigger a heap-based buffer overflow and cause a denial-of-service (service crash) via specially crafted UDP packets. |
| An out-of-bounds read vulnerability in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to cause information disclosure or denial-of-service via a special crafted packet. The leaked memory could be used to bypass ASLR and facilitate further exploitation. |
| An out-of-bounds read vulnerability in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows a remote attacker to leak stack memory and cause a denial of service via a crafted request. The leaked stack memory could be used to bypass ASLR remotely and facilitate exploitation of other vulnerabilities on the affected system. |
| Improper access control in the TeamViewer Full and Host clients (Windows, macOS, Linux) prior version 15.74.5 allows an authenticated user to bypass additional access controls with “Allow after confirmation” configuration in a remote session. An exploit could result in unauthorized access prior to local confirmation. The user needs to be authenticated for the remote session via ID/password, Session Link, or Easy Access as a prerequisite to exploit this vulnerability. |
| Improper verification of cryptographic signature during installation of a VPN driver via the TeamViewer_service.exe component of TeamViewer Remote Clients prior version 15.58.4 for Windows allows an attacker with local unprivileged access on a Windows system to elevate their privileges and install drivers. |
| Improper verification of cryptographic signature during installation of a Printer driver via the TeamViewer_service.exe component of TeamViewer Remote Clients prior version 15.58.4 for Windows allows an attacker with local unprivileged access on a Windows system to elevate their privileges and install drivers. |
