TOP VULNERABILITY THIS WEEK: Remote code execution bug in popular VPN service

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Palo Alto Network’s GlobalProtect Secure Socket Layer (SSL) virtual private network contains remote code execution bug
Description: CVE-2019-1579 is a remote code execution vulnerability in Palo Alto Network’s GlobalProtect Secure Socket Layer (SSL) virtual private network (VPN). At the time of discovery, some systems belonging to ride-sharing service Uber were still at risk, though they have since patched the issue. An attacker could exploit this bug to carry out a buffer overflow, and then gain the ability to remotely execute code on the victim machine.

Title: VMware vulnerability leads to other flaws in NVIDIA Windows GPU display driver
Description: VMware ESXi, Workstation and Fusion are affected by an out-of-bounds read vulnerability that can be triggered using a specially crafted shader file. This vulnerability can be triggered from a VMware guest, affecting the VMware host, leading to a crash (denial-of-service) of the vmware-vmx.exe process on the host. However, when the host/guest systems are using an NVIDIA graphics card, the VMware denial-of-service can be turned into a code execution vulnerability (leading to a VM escape), because of an additional security issue present in NVIDIA’s Windows GPU Display Driver.

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-2019-1125
Title: Microsoft Windows Kernel Information Disclosure Vulnerability
Vendor: Microsoft
Description: An information disclosure vulnerability exists when certain central processing units speculatively access memory. An attacker who successfully exploited the vulnerability could read privileged data across trust boundaries. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it could be used to obtain information that could be used to try to compromise the affected system further.
CVSS v2 Base Score: 4.0 (AV:L/AC:H/Au:N/C:C/I:N/A:N)

ID: CVE-2019-11247
Title: Kubernetes Incomplete Fix Arbitrary File Overwrite Vulnerability
Vendor: Kubernetes
Description: A vulnerability exists in the K8s API that could allow users to read, modify or delete cluster-wide custom resources, even if they only have RBAC permissions for namespaced resources. This vulnerability allows access to a cluster-scoped custom resource if the request is made as if the resource were namespaced. Athorizations for the resource accessed in this manner are enforced using roles and role bindings within the namespace, meaning that a user with access only to a resource in one namespace could create, view update or delete the cluster-scoped resource (according to their namespace role privileges).
CVSS v2 Base Score: 5.1 (AV:N/AC:H/Au:N/C:P/I:P/A:P)

ID: CVE-2019-13377
Title: WPA3 Timing Based Side Channel Vulnerability
Vendor: WPA3
Description: New Side-Channel Attack against WPA3 exists when using brainpool curves. The first vulnerability is a timing-based side-channel attack against WPA3’s Dragonfly handshake when using Brainpool curves, which the WiFi Alliance recommended vendors to use as one of the security recommendations to add another layer of security. The new side-channel leak is located in the password encoding algorithm of Dragonfly.
CVSS v2 Base Score: 5.4 (AV:N/AC:H/Au:N/C:C/I:N/A:N)

ID: CVE-2019-14234
Title: Django JSONField SQL injection Vulnerability
Vendor: Django
Description: Key and index lookups for django.contrib.postgres.fields.JSONField and key lookups for django.contrib.postgres.fields.HStoreField were subject to SQL injection, using a suitably crafted dictionary, with dictionary expansion, as the **kwargs passed to QuerySet.filter().
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:P/I:N/A:N)

ID: CVE-2019-13143
Title: FB50 Smart Lock Information Disclosure Vulnerability
Vendor: Shenzhen Dragon Brother Technology
Description: An HTTP parameter pollution issue was discovered on Shenzhen Dragon Brothers Fingerprint Bluetooth Round Padlock FB50 2.3. With the user ID, user name, and the lock’s MAC address, anyone can unbind the existing owner of the lock, and bind themselves instead. This leads to complete takeover of the lock. The user ID, name, and MAC address are trivially obtained from APIs found within the Android or iOS application. With only the MAC address of the lock, any attacker can transfer ownership of the lock from the current user, over to the attacker’s account. Thus rendering the lock completely inaccessible to the current user.
CVSS v2 Base Score: 4.0 (AV:N/AC:L/Au:S/C:P/I:N/A:N)

ID: CVE-2019-14697
Title: musl libc x87 Stack Overflow Vulnerability
Vendor: musl libc
Description: musl libc has an x87 floating-point stack adjustment imbalance, related to the math/i386/ directory. In some cases, use of this library could introduce out-of-bounds writes that are not present in an application’s source code. This can lead to x87 stack overflow in the execution of subsequent math code, causing it to incorrectly produce a NAN in place of the actual result.
CVSS v2 Base Score: 3.6 (AV:L/AC:L/Au:N/C:N/I:P/A:P)

ID: CVE-2019-14286
Title: Misp Cross Site Scripting Vulnerability
Vendor: Misp
Description: In app/webroot/js/event-graph.js in MISP, a stored XSS vulnerability exists in the event-graph view when a user toggles the event graph view. A malicious MISP event must be crafted in order to trigger the vulnerability.
CVSS v2 Base Score: 4.3 (AV:N/AC:M/Au:N/C:N/I:P/A:N)

ID: CVE-2019-14654
Title: Joomla Remote code Execution Vulnerability
Vendor: Joomla
Description: In Joomla!, inadequate filtering allows users authorised to create custom fields to manipulate the filtering options and inject an unvalidated option.In other words, the filter attribute in subform fields allows remote code execution.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P)
