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.
AnalysisAI
Log tampering in TeamViewer DEX Client versions prior to 26.1 allows adjacent network attackers to inject, modify, or forge entries in the NomadBranch.log file through the UDP network handler, compromising log integrity and audit trail reliability. An attacker with network access can send crafted packets to the Content Distribution Service to manipulate logging records without authentication, potentially obscuring malicious activity or creating false audit entries.
