This can impact log integrity and nonrepudiation.

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 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.

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 privilege escalation vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Exchange-NomadClientHealth-ConfigureGeneralSetting instruction prior V3.4. Improper protection of the execution path on the local device allows attackers, with local access to the device during execution, to hijack the process and execute arbitrary code with SYSTEM privileges.

A privilege escalation vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Nomad-SetWorkRate instruction prior V17.1. The improper handling of executable search paths could allow local attackers with write access to a PATH directory on a device to escalate privileges and execute arbitrary code as SYSTEM.

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-ConfigMgrConsoleExtensions instructions. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands. Exploitation enables remote execution of elevated commands on devices connected to the platform.

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Nomad-PauseNomadJobQueue instruction prior V25. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands. Exploitation enables remote execution of elevated commands on devices connected to the platform.

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-PatchInsights-Deploy instruction prior V15. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands. Exploitation enables remote execution of elevated commands on devices connected to the platform.

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Explorer-TachyonCore-LogoffUser instruction prior V21.1. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands. Exploitation enables remote execution of elevated commands on devices connected to the platform.

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Explorer-TachyonCore-FindFileBySizeAndHash instruction prior V21.1. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands. Exploitation enables remote execution of elevated commands on devices connected to the platform.

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Nomad-GetCmContentLocations instruction prior V19.2. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands. Exploitation enables remote execution of elevated commands on devices connected to the platform.

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Explorer-TachyonCore-CheckSimpleIoC instruction. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands. Exploitation enables remote execution of elevated commands on devices connected to the platform.

A command injection vulnerability was discovered in TeamViewer DEX (former 1E DEX), specifically within the 1E-Explorer-TachyonCore-DevicesListeningOnAPort instruction prior V21. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands. Exploitation enables remote 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 25.11 for Windows allows malicious actors to coerce the service into transmitting data to an arbitrary internal IP address, potentially leaking sensitive information.

A vulnerability in TeamViewer DEX Client (former 1E client) - Content Distribution Service (NomadBranch.exe) prior version 25.11 for Windows allows malicious actors to bypass file integrity validation via a crafted request. By providing a valid hash for a malicious file, an attacker can cause the service to incorrectly validate and process the file as trusted, enabling arbitrary code execution under the Nomad Branch service context.

A vulnerability in TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 25.11 for Windows allows malicious actors to cause a denial of service (application crash) via a crafted command, resulting in service termination.

Improper access control in the clipboard synchronization feature in TeamViewer Full Client prior version 15.57 and TeamViewer Meeting prior version 15.55.3 can lead to unintentional sharing of the clipboard with the current presenter of a meeting.

Improper initialization of default settings in TeamViewer Remote Client prior version 15.51.5 for Windows, Linux and macOS, allow a low privileged user to elevate privileges by changing the personal password setting and establishing a remote connection to a logged-in admin account.

An improper authorization check of local device settings in TeamViewer Remote between version 15.41 and 15.42.7 for Windows and macOS allows an unprivileged user to change basic local device settings even though the options were locked. This can result in unwanted changes to the configuration.
