https://notcve.org/view.php?id=CVE-2022-23242
23 Mar 2022 — TeamViewer Linux versions before 15.28 do not properly execute a deletion command for the connection password in case of a process crash. Knowledge of the crash event and the TeamViewer ID as well as either possession of the pre-crash connection password or local authenticated access to the machine would have allowed to establish a remote connection by reusing the not properly deleted connection password. TeamViewer Linux versiones anteriores a 15.28, no ejecutan correctamente un comando de borrado de la co... • https://www.teamviewer.com/en/trust-center/security-bulletins/TV-2022-1001 • CWE-404: Improper Resource Shutdown or Release •

CVE-2021-35005 – TeamViewer Improper Validation of Array Index Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-35005
20 Jan 2022 — This vulnerability allows local attackers to disclose sensitive information on affected installations of TeamViewer. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the TeamViewer service. 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 array. An attacker can leverage this in conjunction with other vulnerabil... • https://community.teamviewer.com/English/discussion/117794/august-updates-security-patches • CWE-125: Out-of-bounds Read CWE-129: Improper Validation of Array Index •

https://notcve.org/view.php?id=CVE-2020-13699
29 Jul 2020 — 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, tvsqs... • https://packetstorm.news/files/id/180748 • CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •

CVE-2019-18988 – TeamViewer Desktop Bypass Remote Login Vulnerability
https://notcve.org/view.php?id=CVE-2019-18988
07 Feb 2020 — 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 atta... • https://github.com/mr-r3b00t/CVE-2019-18988 • CWE-521: Weak Password Requirements •

CVE-2019-18196

CVE-2019-11769
https://notcve.org/view.php?id=CVE-2019-11769
11 Sep 2019 — 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... • https://blog.to.com/advisory-teamviewer-cve-2019-11769-2 • CWE-522: Insufficiently Protected Credentials •
