openvpn -- multiple TCP clients connecting with the same certificate at the same time can crash the server
James Yonan reports: If two or more client machines try to connect to the server at the same time via TCP, using the same client certificate, and when --duplicate-cn is not enabled on the server, a race condition can crash the server with "Assertion failed at mtcp.c:411"...
openvpn -- denial of service: client certificate validation can disconnect unrelated clients
James Yonan reports: DoS attack against server when run with "verb 0" and without "tls-auth". If a client connection to the server fails certificate verification, the OpenSSL error queue is not properly flushed, which can result in another unrelated client instance on the server seeing the error...
openvpn -- denial of service: malicious authenticated "tap" client can deplete server virtual memory
James Yonan reports: A malicious authenticated client in "dev tap" ethernet bridging mode could theoretically flood the server with packets appearing to come from hundreds of thousands of different MAC addresses, causing the OpenVPN process to deplete system virtual memory as it expands its...
openvpn -- denial of service: undecryptable packet from authorized client can disconnect unrelated clients
James Yonan reports: If the client sends a packet which fails to decrypt on the server, the OpenSSL error queue is not properly flushed, which can result in another unrelated client instance on the server seeing the error and responding to it, resulting in disconnection of the unrelated client...
Windows Unquoted Service Path Privilege Escalation
This module exploits a logic flaw due to how the lpApplicationName parameter is handled. When the lpApplicationName contains a space, the file name is ambiguous. Take this file path as example: C:\program files\hello.exe; The Windows API will try to interpret this as two possible paths:...
