| CVE-2021-34858 | 1 Teamviewer | 1 Teamviewer | 2022-01-21 | 6.8 MEDIUM | 7.8 HIGH |
| This vulnerability allows remote attackers to execute arbitrary code on affected installations of TeamViewer. 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 read past the end of an allocated structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-13606. | |||||
| CVE-2021-34859 | 1 Teamviewer | 1 Teamviewer | 2021-10-27 | 6.8 MEDIUM | 8.8 HIGH |
| 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. | |||||
| CVE-2021-34803 | 2 Microsoft, Teamviewer | 2 Windows, Teamviewer | 2021-07-26 | 4.4 MEDIUM | 7.8 HIGH |
| TeamViewer before 14.7.48644 on Windows loads untrusted DLLs in certain situations. | |||||
| CVE-2020-13699 | 2 Microsoft, Teamviewer | 2 Windows, Teamviewer | 2021-07-21 | 6.8 MEDIUM | 8.8 HIGH |
| 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. | |||||
| CVE-2019-18988 | 1 Teamviewer | 1 Teamviewer | 2020-08-24 | 4.4 MEDIUM | 7.0 HIGH |
| 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. | |||||
| CVE-2019-18251 | 2 Omron, Teamviewer | 2 Cx-supervisor, Teamviewer | 2019-12-11 | 6.8 MEDIUM | 8.8 HIGH |
| 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. | |||||
| CVE-2019-11769 | 1 Teamviewer | 1 Teamviewer | 2019-09-13 | 7.2 HIGH | 7.8 HIGH |
| 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. | |||||
| CVE-2018-14333 | 1 Teamviewer | 1 Teamviewer | 2018-09-17 | 4.3 MEDIUM | 8.1 HIGH |
| TeamViewer through 13.1.1548 stores a password in Unicode format within TeamViewer.exe process memory between "[00 88] and "[00 00 00]" delimiters, which might make it easier for attackers to obtain sensitive information by leveraging an unattended workstation on which TeamViewer has disconnected but remains running. | |||||
