Posted Mar 6, 2019
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3903-2 - USN-3903-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.10. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 18.10 for Ubuntu 18.04 LTS. Jason Wang discovered that the vhost net driver in the Linux kernel contained an out of bounds write vulnerability. An attacker in a guest virtual machine could use this to cause a denial of service or possibly execute arbitrary code in the host kernel. Various other issues were also addressed.

Imperva SecureSphere 13.x PWS Command Injection
Posted Mar 6, 2019
Authored by rsp3ar | Site metasploit.com

This Metasploit module exploits a command injection vulnerability in Imperva SecureSphere version 13.x. The vulnerability exists in the PWS service, where Python CGIs did not properly sanitize user supplied command parameters and directly passes them to corresponding CLI utility, leading to command injection. Agent registration credential is required to exploit SecureSphere in gateway mode. This module was successfully tested on Imperva SecureSphere 13.0/13.1/13.2 in pre-ftl mode and unsealed gateway mode.

Drupal RESTful Web Services unserialize() Remote Code Execution
Posted Mar 6, 2019
Authored by wvu, Charles FOL, Jasper Mattsson, Rotem Reiss | Site metasploit.com

This Metasploit module exploits a PHP unserialize() vulnerability in Drupal RESTful Web Services by sending a crafted request to the /node REST endpoint. As per SA-CORE-2019-003, the initial remediation was to disable POST, PATCH, and PUT, but Ambionics discovered that GET was also vulnerable (albeit cached). Cached nodes can be exploited only once.

RealTerm Serial Terminal 2.0.0.70 Echo Port Buffer Overflow
Posted Mar 6, 2019
Authored by Matteo Malvica, Hodorsec, Alejandra Sanchez

RealTerm Serial Terminal version 2.0.0.70 suffers from an echo port buffer overflow vulnerability. Modifications to the original proof of concept include the fact that it uses a larger payload size for shellcode due to different jump offsets and filters the bad character 0x3a as this is the character for port which causes an error ":".

OpenSSL Security Advisory 20190306
Posted Mar 6, 2019
Site openssl.org

OpenSSL Security Advisory 20190306 - ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value (IV) should be 96 bits (12 bytes). OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also incorrectly allows a nonce to be set of up to 16 bytes. In this case only the last 12 bytes are significant and any additional leading bytes are ignored.

Scapy Packet Manipulation Tool 2.4.3rc1
Posted Mar 6, 2019
Authored by Philippe Biondi | Site secdev.org

Scapy is a powerful interactive packet manipulation tool, packet generator, network scanner, network discovery tool, and packet sniffer. It provides classes to interactively create packets or sets of packets, manipulate them, send them over the wire, sniff other packets from the wire, match answers and replies, and more. Interaction is provided by the Python interpreter, so Python programming structures can be used (such as variables, loops, and functions). Report modules are possible and easy to make. It is intended to do the same things as ttlscan, nmap, hping, queso, p0f, xprobe, arping, arp-sk, arpspoof, firewalk, irpas, tethereal, tcpdump, etc.

Changes: Release candidate 1 for 2.4.3. Various updates.
