Dell has released a second patch in as many months for its laptop bloatware known as SupportAssist, a utility that’s meant to help solve problems but which could give hackers a way to compromise a vulnerable computer. 

Dell has released updates for SupportAssist for Business and SupportAssist for Home due to vulnerabilities found in a component called PC Doctor, a product from a US vendor that sells diagnostics software to hardware OEMs to monitor a system’s health.  

It’s likely this bug has a wide impact because SupportAssist ships with most Dell laptops and computers running Windows 10.

Dell patched a serious bug in SupportAssist in April after an independent security researcher found the support tool could be used by remote attackers to take over millions of vulnerable systems.     

While that bug resided in Dell’s SupportAssist code itself, this vulnerability sits inside a third-party software library provided by PC Doctor, called ‘Common.dll’. That means it could affect PCs from other OEMs that use PC Doctor software. 

In an advisory, Dell is urging users of its hardware to update to Dell SupportAssist for Business PCs version 2.0.1 and Dell SupportAssist for Home PCs version 3.2.2. 

The bug, tracked as CVE-2019-12280, affects SupportAssist for Business PCs version 2.0 and SupportAssist for Home PCs version 3.2.1 and earlier. Dell rates the bug as a high-severity issue. 

PC Doctor for its part says it is the “world’s leading hardware diagnostic and system information tool [that] keeps your devices running their best”, offering OEMs “hardware diagnostics, advanced system information, system history, monitoring tools, and more”.

Peleg Hada, a researcher from security firm SafeBreach, reported the bug to Dell and has posted a detailed explanation of the problem. 

On Windows 10 Dell machines, a high-privilege service called ‘Dell Hardware Support’ seeks out several software libraries that could be used by a local attacker to escalate privileges. 

Hada explains that a regular user could replace a software library with one of their own to achieve code execution as the operating system. This can be achieved by using a utility library used by PC Doctor called Common.dll. 

Hada notes that the “program doesn’t validate whether the DLL that it will load is signed” and this means “it will load an arbitrary unsigned DLL”.

Other hardware could be affected by products that use PC Doctor as their base for similar diagnostic services. These products include Corsair One Diagnostics, Corsair Diagnostics, Staples EasyTech diagnostics, Tobii I-Series diagnostic tool, and Tobii Dynavox diagnostic tool.

Work from Home Security

Published

Spin Master is a leading global children’s entertainment company that invents toys and games, produces dozens of television and studio series that are distributed in 160 countries, and creates a variety of digital games played by more than 30 million children. What was once a small private company founded by childhood friends is now a public global supply chain with over 1,500 employees and 28 offices around the world.

Like most organizations in 2020, Spin Master had to adapt quickly to the new normal of remote work, shifting most of its production from cubicles in regional and head offices to hundreds of employees working from home and other remote locations.

This dramatic shift created potential security risks, as most employees were no longer behind the firewall on the corporate network. Without the implementation of hardened endpoint security, the door would be open for bad actors to infiltrate the organization, acquire intellectual property, and ransom customer information. Additionally, the potential downtime caused by a security breach could harm the global supply chain. With that in mind, Spin Master created a self-imposed 30-day deadline to extend its network protection capabilities to the edge.

Key Findings:

  • Think Long Term: The initial goal of establishing a stop-gap work-from-home (WFH) and work-from-anywhere (WFA) strategy has since morphed into a permanent strategy, requiring long-term solutions.
  • Gather Skills: The real urgency posed by the global pandemic made forging partnerships with providers that could fill all the required skill sets a top priority.
  • Build Momentum: The compressed timeline left no room for delay or error. The Board of Directors threw its support behind the implementation team and gave it broad budget authority to ensure rapid action, while providing active guidance to align strategy with action.
  • Deliver Value: The team established two key requirements that the selected partner must deliver: implementation support and establishing an ongoing managed security operations center (SOC).

Key Criteria for Evaluating Privileged Access Management

Published

on

Privileged Access Management (PAM) enables administrative access to critical IT systems while minimizing the chances of security compromises through monitoring, policy enforcement, and credential management.

A key operating principle of all PAM systems is the separation of user credentials for individual staff members from the system administration credentials they are permitted to use. PAM solutions store and manage all of the privileged credentials, providing system access without requiring users to remember, or even know, the privileged password. Of course, all staff have their own unique user ID and password that they use to complete everyday tasks such as accessing email and writing documents. Users who are permitted to handle system administration tasks that require privileged credentials log into the PAM solution, which provides and controls such access according to predefined security policies. These policies control who is allowed to use which privileged credentials when, where, and for what tasks. An organization’s policy may also require logging and recording of the actions undertaken with the privileged credentials.

Once implemented, PAM will improve your security posture in several ways. The first is by segregating day-to-day duties from duties that require elevated access, reducing the risk of accidental privileged actions. Secondly, automated password management reduces the possibility that credentials will be shared while also lowering the risk if credentials are accidentally exposed. Finally, extensive logging and activity recording in PAM solutions aids audits of critical system access for both preventative and forensic security.

Companies always want to enhance their ability to quickly address pressing business needs. Toward that end, they look for new ways to make their IT infrastructures more efficient—and more cost effective. Today, those pressing needs often center around data protection and regulatory compliance, which was certainly the case for Adventist Risk Management. What they wanted was an end-to-end, best-in-class solution to meet their needs. After trying several others, they found the perfect combination with HYCU and Nutanix, which provided:

  • Ease of deployment
  • Outstanding ROI
  • Overall TCO improvement

Nutanix Cloud Platform provides a software-defined hyperconverged infrastructure, while HYCU offers purpose-built backup and recovery for Nutanix. Compared to the previous traditional infrastructure and data protection solutions in use at Adventist Risk Management, Nutanix and HYCU simplified processes, speeding day-to-day operations up to 75%. Now, migration and update activities typically scheduled for weekends can be performed during working hours and help to increase IT staff and management quality of life. HYCU further increased savings by providing faster and more frequent points of recovery as well as better DR Recovery Point Objective (RPO) and Recovery Time Objective (RTO) by increasing the ability to do daily backups from one to four per day.

Furthermore, the recent adoption of Nutanix Objects, which provides secure and performant S3 storage capabilities, enhanced the infrastructure by:

    • Improving overall performance for backups
    • Adding security against potential ransomware attacks
    • Replacing components difficult to manage and support

In the end, Nutanix and HYCU enabled their customer to save money, improve the existing environment, and, above all, meet regulatory compliance requirements without any struggle.
