@Risk: Security Alert
OUCH! Security Awareness
Case Leads DFIR Digest
Industrial Control Systems
Industrials & Infrastructure


@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.

NOTABLE RECENT SECURITY ISSUES

SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP


Title: Cisco patches remote code execution vulnerability in Communications Manager

Description: Cisco disclosed, and fixed, a remote code execution bug in its Communications Manager that could allow an attacker to remotely execute code on the victim's system. The high-severity bug requires a patch, as there are no workarounds. An attacker could exploit this vulnerability by authenticating to the targeted system using administrator-level privileges and uploading a specially crafted file.

Reference: https://threatpost.com/cisco-high-severity-bugs/145446/

Snort SIDs: 50320

 

Title: Multiple vulnerabilities in Schneider Electric Modicon M580

Description: There are several vulnerabilities in the Schneider Electric Modicon M580 that could lead to a variety of conditions, including denial of service and the disclosure of sensitive information. The Modicon M580 is the latest in Schneider Electric's Modicon line of programmable automation controllers. The majority of the bugs exist in UMAS requests made while operating the hardware.

RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE

COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM


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-2019-1040

Title:    Microsoft Windows NTLM Tampering Vulnerability

Vendor:    Microsoft

Description: A tampering vulnerability exists in Microsoft Windows when a man in the middle attacker is able to successfully bypass the NTLM MIC (Message Integrity Check) protection. An attacker who successfully exploited this vulnerability could gain the ability to downgrade NTLM security features. To exploit this vulnerability, the attacker would need to tamper with the NTLM exchange. The attacker could then modify flags of the NTLM packet without invalidating the signature. The vulnerabilities allow attackers to remotely execute malicious code on any Windows machine or authenticate to any HTTP server that supports Windows Integrated Authentication (WIA) such as Exchange or ADFS.

CVSS v2 Base Score:    5.4 (AV:N/AC:H/Au:N/C:N/I:C/A:N)


ID:        CVE-2019-12308

Title:    Microsoft Windows Security Feature Bypass Vulnerability

Vendor:    Microsoft

Description: A security feature bypass vulnerability exists where a NETLOGON message is able to obtain the session key and sign messages. To exploit this vulnerability, an attacker could send a specially crafted authentication request. An attacker who successfully exploited this vulnerability could access another machine using the original user privileges. The issue has been addressed by changing how NTLM validates network authentication messages. These vulnerabilities allow attackers to remotely execute malicious code on any Windows machine or authenticate to any HTTP server that supports Windows Integrated Authentication (WIA) such as Exchange or ADFS.

CVSS v2 Base Score:    7.6 (AV:N/AC:H/Au:N/C:C/I:C/A:C)


ID:        CVE-2019-0973

Title:    Microsoft Windows Installer DLL Loading Local Privilege Escalation Vulnerability

Vendor:    Microsoft

Description: Microsoft Windows is exposed to a local privilege escalation vulnerability. A local attacker can leverage this issue to execute arbitrary code with elevated privileges. An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

CVSS v2 Base Score:    7.2 (AV:L/AC:L/Au:N/C:C/I:C/A:C)


ID:        CVE-2019-12735

Title:    Vim and Neovim Arbitrary Code Execution Vulnerability

Vendor:    Vim

Description: Vim and Neovim are exposed to an arbitrary code execution vulnerability. Successfully exploiting this issue can allow an attacker to execute arbitrary code on the affected system. getchar.c in Vim and Neovim allows remote attackers to execute arbitrary OS commands via the ":source!"" command in a modeline, as demonstrated by execute in Vim, and assert_fails or nvim_input in Neovim.

CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)


ID:        CVE-2019-9501

Title:    Broadcom WiFi Chipset Drivers Multiple Heap Buffer Overflow Vulnerabilities

Vendor:    Broadcom

Description: By supplying a vendor information element with a data length larger than 32 bytes, a heap buffer overflow is triggered in wlc_wpa_sup_eapol.

Vulnerabilities in the open source brcmfmac driver. By supplying a vendor information element with a data length larger than 32 bytes, a heap buffer overflow is triggered in wlc_wpa_sup_eapol.

CVSS v2 Base Score:    7.6 (AV:N/AC:H/Au:N/C:C/I:C/A:C)


ID:        CVE-2019-9503

Title:    Linux Kernel Security Bypass and Heap Buffer Overflow Vulnerabilities

Vendor:    Linux

Description: Linux Kernel is exposed to a security bypass vulnerability and heap based buffer overflow vulnerability. Attackers may exploit these issues to execute arbitrary code within the context of the affected application. Failed exploits may result in denial of service conditions. The Broadcom brcmfmac driver could allow a remote malicious user to bypass security restrictions. By receiving firmware event frames from a remote source, a remote attacker could exploit this vulnerability to bypass the frame validation.

CVSS v2 Base Score:    7.8 (AV:N/AC:L/Au:N/C:N/I:C/A:N)


ID:        CVE-2019-0307

Title:    SAP Solution Manager Remote Information Disclosure Vulnerability

Vendor:    SAP

Description: SAP Solution Manager is exposed to an information disclosure vulnerability. Successfully exploiting this issue may allow an attacker to obtain sensitive information that may aid in further attacks.

CVSS v2 Base Score: 3.3    (AV:N/AC:L/Au:M/C:P/I:N/A:N)
