Title: Cisco patches dozen vulnerabilities in Data Center Network Manager

Description: Cisco released multiple security advisories last week announcing patches for 12 vulnerabilities in the Data Center Network Manager software. The software allows users to manage their Cisco switches and fabric extenders. Three of the vulnerabilities disclosed (CVE-2019-15975, CVE-2019-15976 and CVE-2019-15977) could allow an unauthenticated, remote attacker to bypass authentication and carry out a variety of malicious tasks with administrative privileges on an affected device.

Title: Buffer overflow vulnerabilities in OpenCV

Description: Cisco Talos recently discovered two buffer overflow vulnerabilities in the OpenCV libraries. An attacker could potentially exploit these bugs to cause heap corruptions and potentially code execution. Intel Research originally developed OpenCV in 1999, but it is currently maintained by the non-profit organization OpenCV is used for numerous applications, including facial recognition technology, robotics, motion tracking and various machine learning programs.

Companies, organizations and government agencies in the U.S. are anxiously bracing for a retaliatory cyber attack from Iran after an American drone attack on a top Iranian general.

The U.S. Department of Homeland Security even went so far as to release a warning telling companies to "consider and assess" the possible damage a state-sponsored attack from Iran could have on their operations.

Homeland Security is expected to push for legislation in 2020 that would allow them to subpoena internet companies to protect infrastructure from cyber attacks.

Currency exchange marketplace Travelex's website was still down as of Tuesday morning after an attack on New Year's Eve. The company referred to the attack as a "software virus."

England is looking into whether malware caused an outage at the London stock exchange in August, though the trading outage was initially blamed on a software glitch. (Please note that this story is behind a paywall.)

Wyze smart camera users are urged to reset their passwords and reconnect third-party apps after researchers discovered an exposed database containing users' personal information.

A Japanese intelligence agency released a warning that it is expecting state-sponsored cyber attacks on the 2020 Olympic Games slated to take place later this year after it discovered a series of targeted phishing emails.

Attackers are still exploiting a vulnerability in the Pulse Secure VPN service to deliver malware that deletes the victim's backup files and disables endpoint security controls.

ID: CVE-2019-16278

Title: Nostromo Web Server Unauthenticated Remote Code Execution Vulnerability

Vendor: Nazgul

Description: A remote code execution vulnerability exists in Nostromo Web Server. This issue is caused by a directory traversal in the function http_verify in nostromo nhttpd allowing an attacker to achieve remote code execution via a crafted HTTP request. After successful exploitation of this vulnerability an attacker can achieve remote code execution via a crafted HTTP request.

CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)

ID: CVE-2019-5596

Title: FreeBSD Privilege Escalation Vulnerability

Vendor: FreeBSD

Description: In FreeBSD, a bug in the reference count implementation for UNIX domain sockets can cause a file structure to be incorrectly released potentially allowing a malicious local user to gain root privileges or escape from a jail. FreeBSD attempts to handle the case where the receiving process does not provide a sufficiently large buffer for an incoming control message containing rights. The code which performs this operation failed to release a reference obtained on the file corresponding to a received right. This bug can be used to cause

the reference counter to wrap around and free the file structure.

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

ID: CVE-2019-1405

Title: Microsoft UPnP Local Privilege Elevation Vulnerability

Vendor: Microsoft

Description: An elevation of privilege vulnerability exists when the Windows Universal Plug and Play service improperly allows COM object creation. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges.

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

ID: CVE-2019-19726

Title: OpenBSD Dynamic Loader chpass Privilege Escalation Vulnerability

Vendor: Pulse Secure

Description: Qualys discovered a local privilege escalation in OpenBSD's dynamic loader ( This vulnerability is exploitable in the default installation (via the set-user-ID executable chpass or passwd) and yields full root privileges. OpenBSD allows local users to escalate to root because a check for LD_LIBRARY_PATH in setuid programs can be defeated by setting a very small RLIMIT_DATA resource limit. When executing chpass or passwd (which are setuid root), _dl_setup_env in tries to strip LD_LIBRARY_PATH from the environment, but fails when it cannot allocate memory. Thus, the attacker is able to execute their own library code as root.

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

ID: CVE-2019-1184

Title: Windows Shell COM Server Registrar Local Privilege Escalation Vulnerability

Vendor: Microsoft

Description: An elevation of privilege vulnerability exists when Windows Core Shell COM Server Registrar improperly handles COM calls. An attacker who successfully exploited this vulnerability could potentially set certain items to run at a higher level and thereby elevate permissions.

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

ID: CVE-2019-19844

Title: Django count Hijack Vulnerability

Vendor: Django

Description: Django allows account takeover. A suitably crafted email address (that is equal to an existing user's email address after case transformation of Unicode characters) would allow an attacker to be sent a password reset token for the matched user account. Django's password-reset form uses a case-insensitive query to retrieve accounts matching the email address requesting the password reset.

CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:N/I:P/A:N)
