Operationally, ranked in the top 9.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability CVE-2024-7479 is an instance of improper cryptographic signature verification (CWE-347) that occurs during installation of a VPN driver through the TeamViewer_service.exe component. It affects TeamViewer Remote Clients for Windows prior to version 15.58.4 and carries a CVSS 3.1 base score of 8.8.
An attacker who already possesses local unprivileged access on the Windows host can exploit the flaw to bypass signature checks, elevate privileges, and install arbitrary drivers, resulting in full control over confidentiality, integrity, and availability within the affected security context.
The vendor advisory at https://www.teamviewer.com/en/resources/trust-center/security-bulletins/tv-2024-1006/ identifies the issue and directs users to update to TeamViewer Remote Client version 15.58.4 or later to restore proper signature validation during driver installation.
EPSS remains flat at 0.0587 with no material increase since disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires verification of digital signatures using organization-approved certificates before installation, directly preventing improper verification of cryptographic signatures.
Component authenticity commonly depends on cryptographic signatures; the control enforces proper verification of those signatures.
PKI certificates under an approved policy require cryptographic signature verification on issuance and validation.
Requires cryptographic signatures on authoritative data and support for verifying the chain of trust.
Mandates verification of cryptographic signatures (e.g., DNSSEC RRSIG) on resolution responses, addressing missing or bypassed signature checks.
Integrity tools commonly rely on cryptographic signatures whose improper validation this weakness covers.
Authenticity validation commonly relies on cryptographic signature or certificate checks that this control enforces.
