This module exploits a memory corruption vulnerability in the Linux kernel. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption that can be used by an attacker to escalate privileges.
This module exploits a signedness error condition in the Linux Kernel via PACKET_RX_RING option on an AF_PACKET socket with a TPACKET_V3 ring buffer version enabled. The packet_set_ring function in net/packet/af_packet.c in the Linux kernel through 4.10.6 does not properly validate certain block-size data, which allows local users to escalate privileges.
This module exploits a double-free vulnerability in the Linux Kernel. The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel through 4.9.11 mishandles DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allows local users to escalate privileges via an application that makes an IPV6_RECVPKTINFO setsockopt system call.
This module injects .so library into the remote smbd process. For this exploit to work, a writable shared directory must be available, in order to write an so library. The agent will normally run as the "nobody" user, and will have limited capabilities.
This module exploits a signedness issue in the Linux Kernel. The sock_setsockopt function in net/core/sock.c in the Linux kernel before 4.8.14 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to escalate privileges. This module performs a CAP_NET_ADMIN to root privilege escalation.
