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.

TeamViewer Desktop para Windows versiones anteriores a 15.8.3 no cita apropiadamente sus manejadores de URI personalizados. Un sitio web malicioso podría iniciar TeamViewer con parámetros arbitrarios, como es demostrado por un teamviewer10: --play URL. Un atacante podría forzar a una víctima para enviar una petición de autenticación NTLM y retransmitir la petición o capturar el hash para descifrar la contraseña fuera de línea. Esto afecta a teamviewer10, teamviewer8, teamviewerapi, tvchat1, tvcontrol1, tvfiletransfer1, tvjoinv8, tvpresent1, tvsendfile1, tvsqcustomer1, tvsqsupport1, tvvideocall1 y tvvpn1. El problema se corrigió en las versiones 8.0.258861, 9.0.258860, 10.0.258873, 11.0.258870, 12.0.258869, 13.2.36220, 14.2.56676, 14.7.48350 y 15.8.3
