Newsletters: @RISK


@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data

A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

This is a list of recent vulnerabilities for which exploits are available. System administrators can use this list to help in prioritization of their remediation activities. The Qualys Vulnerability Research Team compiles this information based on various exploit frameworks, exploit databases, exploit kits and monitoring of internet activity.

ID: CVE-2014-8517
Title: tnftp Command Execution Vulnerability
Vendor: FreeBSD
Description: The fetch_url function in usr.bin/ftp/fetch.c in tnftp, as used in NetBSD 5.1 through 5.1.4, 5.2 through 5.2.2, 6.0 through 6.0.6, and 6.1 through 6.1.5 allows remote attackers to execute arbitrary commands via a | (pipe) character at the end of an HTTP redirect.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)

ID: CVE-2014-6324
Title: Microsoft Windows Kerberos Checksum Privilege Escalation Vulnerability (MS14-068)
Vendor: Microsoft
Description: The Kerberos Key Distribution Center (KDC) in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, and Windows Server 2012 Gold and R2 allows remote authenticated domain users to obtain domain administrator privileges via a forged signature in a ticket, as exploited in the wild in November 2014, aka "Kerberos Checksum Vulnerability."
CVSS v2 Base Score: 9.0 (AV:N/AC:L/Au:S/C:C/I:C/A:C)

ID: CVE-2014-4114
Title: Microsoft Windows OLE - Remote Code Execution "Sandworm" Exploit (MS14-060)
Vendor: Microsoft
Description: Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allow remote attackers to execute arbitrary code via a crafted OLE object in an Office document, as exploited in the wild with a "Sandworm" attack in June through October 2014, aka "Windows OLE Remote Code Execution Vulnerability."
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2014-7169
Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2014-6271
Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

Vendor: OpenSSL Project
Description: The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeart Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:P/I:N/A:N)
