Recent Security Issues


SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP


Title: WastedLocker adding new techniques, makes headlines

Description: The WastedLocker ransomware is now using the Windows memory management feature to evade detection. This malware has made headlines recently for its expanded use, and has even potentially been linked to a recent cyber attack on GPS service provider Garmin. WastedLocker now has the ability to disguise its actions and bypass any ransomware protections that are already deployed on a victim machine.

Title: Microsoft fixes vulnerabilities in Azure Sphere

Description: Cisco Talos researchers recently discovered seven vulnerabilities in Microsoft's Azure Sphere, a cloud-connected SoC platform designed specifically with IoT application security in mind. The infrastructure around the Azure Sphere platform is Microsoft's Azure Sphere cloud, which takes care of secure updates, app deployment, and periodically verifying the device integrity. Internally, the SoC is made up of a set of several ARM cores that have different roles. The researchers discovered two chainable vulnerabilities within Azure Sphere that, assuming an attacker could flash a malicious application, would allow for arbitrary writing to anywhere in the /mnt/config partition, resulting in further privilege escalation.

Vulnerabilities with Exploits


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-2020-3382

Title: Cisco Data Center Network Manager Authentication Bypass Vulnerability

Vendor: Cisco

Description: The vulnerability is due to insufficient validation of user input on the web management interface. An attacker could exploit this vulnerability by submitting a malicious request to an affected system. An exploit could allow the attacker to gain administrative-level privileges on the system. The attacker needs a valid username to exploit this vulnerability.

CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)


ID: CVE-2020-10713

Title: GRUB2 bootloader Buffer Overflow Vulnerability

Vendor: Multi-Vendor

Description: A flaw was found in grub2, where an attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access to the system such as gaining physical access, obtain the ability to alter a pxe-boot network, or have remote access to a networked system with root access. With this access, an attacker could then craft a string to cause a buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVSS v3 Base Score: 6.7 (AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H)


ID: CVE-2020-3187

Title: Cisco ASA Software and FTD Software Web Services Path Traversal Vulnerability

Vendor: Cisco

Description: A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to conduct directory traversal attacks and obtain read and delete access to sensitive files on a targeted system. The vulnerability is due to a lack of proper input validation of the HTTP URL. An attacker could exploit this vulnerability by sending a crafted HTTP request containing directory traversal character sequences.

CVSS v3 Base Score: 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N)


ID: CVE-2020-3452

Title: Cisco ASA Software and FTD Software Web Services Read-Only Path Traversal Vulnerability

Vendor: Cisco

Description: A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to conduct directory traversal attacks and read sensitive files on a targeted system. The vulnerability is due to a lack of proper input validation of URLs in HTTP requests processed by an affected device. An attacker could exploit this vulnerability by sending a crafted HTTP request containing directory traversal character sequences to an affected device.

CVSS v3 Base Score: 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)


ID: CVE-2020-8163

Title: Ruby On Rails Remote Code Execution Vulnerability

Vendor: Ruby On Rails

Description: The is a code injection vulnerability that would allow an attacker who controlled the "locals" argument of a "render" call to perform a remote code execution vulnerability.

CVSS v3 Base Score: 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)


ID: CVE-2020-4534

Title: IBM WebSphere Application Server Remote Code Execution Vulnerability

Vendor: IBM

Description: IBM WebSphere Application Server could allow a local authenticated attacker to gain elevated privileges on the system, caused by improper handling of UNC paths. By scheduling a task with a specially-crafted UNC path, an attacker could exploit this vulnerability to execute arbitrary code with higher privileges.

CVSS v3 Base Score: 8.8 (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H)


ID: CVE-2020-8607

Title: Trend Micro Rootkit Driver Input Validation Vulnerability

Vendor: Trend Micro

Description: An input validation vulnerability found in multiple Trend Micro products utilizing a particular version of a specific rootkit protection driver could allow an attacker in user-mode with administrator permissions to abuse the driver to modify a kernel address that may cause a system crash or potentially lead to code execution in kernel mode. An attacker must already have obtained administrator access on the target machine (either legitimately or via a separate unrelated attack) to exploit this vulnerability.

CVSS v3 Base Score: 6.7 (AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H)


ID: CVE-2020-3698

Title: Qualcomm Out-Of-Bounds Memory Corruption Vulnerability

Vendor: Qualcomm

Description: An Out of bound write happens in the component QoS DSCP when mapping due to improper input validation for data received from association response frame in Qualcomm Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music and Snapdragon Wearables (Chip Software).

CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
