Onapsis Security Advisory - JDENet is a network communication middleware that performs network communications workstation-to-server and server-to-server. It is used to call remote functions, to authenticate users and transmit information between hosts in a JD Edwards environment. If a specially-crafted UDP packet is sent to the JDENet port, the JDENET service creates a TCP connection to the provided IP and PORT parameters. This connection could be used to access the JDENET and all ERP functionality provided through that callback connection.

This Metasploit module exploits a chain of vulnerabilities in the Accellion File Transfer appliance. This appliance exposes a UDP service on port 8812 that acts as a gateway to the internal communication bus. This service uses Blowfish encryption for authentication, but the appliance ships with two easy to guess default authentication keys. This Metasploit module abuses the known default encryption keys to inject a message into the communication bus. In order to execute arbitrary commands on the remote appliance, a message is injected into the bus destined for the 'matchrep' service. This service exposes a function named 'insert_plugin_meta_info' which is vulnerable to an input validation flaw in a call to system(). This provides access to the 'soggycat' user account, which has sudo privileges to run the primary admin tool as root. These two flaws are fixed in update version FTA_8_0_562.

Nmap is a utility for port scanning large networks, although it works fine for single hosts. Sometimes you need speed, other times you may need stealth. In some cases, bypassing firewalls may be required. Not to mention the fact that you may want to scan different protocols (UDP, TCP, ICMP, etc.). Nmap supports Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses some packet filters), TCP ACK and Window scanning, UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Direct (non portmapper) RPC scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning. Nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings.

A vulnerability exists in EMC NetWorker which can be exploited to potentially create a denial of service condition or eavesdrop on process communications. EMC Networker uses an RPC library to provide a portmapper service within nsrexecd. The portmapper restricts access for service commands to the localhost. However, the UDP protocol allows malicious users to spoof the source address of the network packet making it appear it originated from the localhost. This potentially may allow a remote malicious user to unregister existing NetWorker RPC services or register new RPC services. EMC NetWorker versions 7.5.3.5, 7.5 SP4 and later, and 7.6.1.2 and later are affected.

Zero Day Initiative Advisory 10-284 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell ZENWorks. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ZenRem32.exe process which listens by default on TCP and UDP ports 1761. When processing the Console DN field of incoming requests, the process can be made to overflow a stack buffer by 2 bytes. Due to the location of the destination buffer, an attacker can abuse this to overwrite a portion of a return address and execute remote code under the context of the SYSTEM user.

Zero Day Initiative Advisory 10-283 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell ZENWorks. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ZenRem32.exe process which listens by default on TCP and UDP ports 1761. When processing incoming connections with specific version fields the process fails to initialize a string buffer intended to hold the name of the client. After making allocations based on the size of the uninitialized string, ZenRem32 proceeds to convert the buffer between wide-char and multi-byte data types. As the pointer is directed at uninitialized memory, this can be abused to corrupt the heap. An attacker can leverage this to execute remote code under the context of the SYSTEM user.

ipt_pkd is an iptables extension implementing port knock detection. This project provides 3 parts: the kernel module ipt_pkd, the iptables user space module libipt_pkd.so, and a user space client knock program. For the knock packet, it uses a UDP packet sent to a random port that contains a SHA-256 of a timestamp, small header, random bytes, and a shared key. ipt_pkd checks the time window of the packet and does the SHA-256 to verify the packet. The shared key is never sent.
