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.
AI Analysis
Technical Summary
TeamViewer Full Client and Host for Linux prior to version 15.82 contain a CWE-59 improper link resolution vulnerability in the Cloud Session Recording (CSR) feature. This flaw arises from a race condition during path validation and subsequent file access, enabling a local authenticated attacker with low privileges to cause privileged file operations at unintended file system locations. The vulnerability has a CVSS 3.1 base score of 7.0, indicating high severity, with attack vector local, high attack complexity, low privileges required, no user interaction, and impacts on confidentiality, integrity, and availability.
Potential Impact
An attacker with local authenticated access can exploit this vulnerability to perform privileged file operations in unintended locations, potentially leading to unauthorized modification or disclosure of sensitive files and disruption of system availability. The vulnerability affects confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
