At BestCybersecurityNews, we help entrepreneurs, solopreneurs, young learners, and seniors learn more about cybersecurity.
In the context of Microsoft Azure, a vulnerability or attack is a flaw in an application. These flaws affect various components of Azure, including the Open Management Infrastructure (OMI), Azure Application Gateway Web Application Firewall, Azure Synapse Analytics, and Azure Data Factory. You should know about these vulnerabilities and learn how to protect your applications.

A new vulnerability in the Open Management Infrastructure (OMI) service in Azure can allow a remote code execution (RCE) attack. The exploit exploits a flaw in the way an OMI software agent authenticates itself. The flaw enables an attacker to execute arbitrary code on the affected system and could even allow the attacker to gain root access. It affects several Azure services, including Azure Automation, Azure Automatic Update, Azure Operations Management Suite, Log Analytics, Configuration Management, and Diagnostics.
A recent security patch for the OMI vulnerability in Azure has been released by Microsoft. However, any Azure VMs that are vulnerable to the vulnerability must manually update their OMI agents. The vulnerable OMI agents were installed via shell bundles and extensions. The company’s announcement has included scripts for IT professionals to check for vulnerable OMI instances.
Open Management Infrastructure (OMI) is a UNIX/Linux equivalent of Windows Management Instrumentation (WMI). It is deployed on many Linux virtual machines in Azure and is widely used to manage configurations and collect statistics. However, because this open-source software is used by so many organizations, some organizations may not know that they are exposed to this vulnerability. In addition, the OMI agent installs silently on Linux VMs and runs at the highest level of privilege.
A remote code execution vulnerability has been discovered in the Open Management Infrastructure (OMI) service. It could allow hackers to gain access to sensitive data and execute commands. The exploit code is available on the internet and is likely to be exploited in the wild. Microsoft has released patches to address this vulnerability in its Azure service.
The OMI vulnerability is caused by a conditional statement coding mistake and an uninitialized authentication struct. The exploit would allow an attacker to gain root access to a vulnerable host. The exploit would also allow the attacker to execute arbitrary code on the affected system. The CVE number for this vulnerability is CVE-2021-38648. This vulnerability is critical for organizations using Azure services.
A recent flaw in the Azure Service Fabric Explorer has been found to allow an attacker to gain administrator privileges. The flaw is tracked as CVE-2022-35829 and carries a CVSS severity rating of 6.2. Microsoft fixed the flaw as part of their October 2022 Patch Tuesday update. The Azure Fabric Explorer is used to manage clusters of Azure Service Fabric applications.
The vulnerability is present in the Service Fabric Explorer tool and affects versions 8.1.316 and earlier. It allows an attacker to abuse full Administrator permissions to take over Service Fabric clusters and install malicious applications. Researchers at Orca Security found the flaw in August and reported it to Microsoft’s Security Response Center. Microsoft published patches for the flaw during this month’s Patch Tuesday. To protect against the vulnerability, customers should update to the latest SFX version.
Service Fabric Explorer is an application that admins use to manage clusters and inspect applications and services. Administrators can use the application to start and restart clusters, inspect applications, and manage nodes. Microsoft has updated the Service Fabric Explorer in its updates and update guide. This vulnerability affects the deployment name, which is accessed by cluster administrators.
Microsoft has patched several vulnerabilities in its Azure Service Fabric. One of them is the FabriXss vulnerability in Azure Service Fabric Explorer, which has full admin privileges. The vulnerability has been tracked as CVE-2022-35829 and was fixed in the October Patch Tuesday release. However, older versions of this tool are vulnerable to this vulnerability.
Using an Azure Application Gateway Web Application Firewall is a good way to safeguard your web applications against attack. It can block SQL injections, Cross-Site Scripting, and malware uploads. It also protects against DDoS attacks. These are all common vulnerabilities and attacks, and they require a proactive security management strategy.
The Azure Application Gateway Web Application Firewall (WAF) can be used as a standalone service or in conjunction with the Azure Application Gateway and Azure CDN. The WAF provides basic security for clusters, but you’ll likely need more than WAF to protect against attacks. While it offers some important protection, WAF has several limitations that you need to be aware of.
A WAF can block malicious traffic by inspecting traffic. It can also block requests that contain signatures of attacks. The WAF engine in the Azure Application Gateway Web Application Firewall uses two modes to determine the severity of an attack. In the prevention mode, a single Critical rule match will result in a blocked request. In the detection mode, a single Warning rule match will increase the Anomaly Score by three, but not enough to block traffic. You can configure and manage the firewall in the Azure portal or through REST APIs. You can also manage WAF policies using Azure PowerShell and Azure Resource Manager templates. You can also manage your policy at scale with the Firewall Manager integration.
When using Azure Application Gateway, it is important to enable end-to-end SSL to protect against vulnerabilities. Without this protection, you can’t transmit sensitive data to the backend securely. Additionally, you can’t be sure of the authenticity of your instances. A good Azure Application Gateway will protect your infrastructure by providing certificate protection.
Using Azure Application Gateway WAF is a great way to secure your Azure web applications. This product supports web apps that are built using ASP.NET MVC, KnockoutJS, REST API, and other web development technologies. It also provides SSL termination at the Gateway, which frees up your web servers from the overhead of encryption.
Security researchers from Orca Security have discovered a new Azure Synapse Analytics & Azure Data factory vulnerability that may have allowed an attacker to access sensitive data. The vulnerability, called SynLapse, affects the way data is integrated into network environments and has a severe impact on the security of cloud applications. Orca says the vulnerability is due to weaknesses in the architecture of Azure Synapse. Specifically, the flaw affects a part of the Integration Runtime (IR) application that connects to Amazon Redshift. This vulnerability could allow attackers to access user credentials and run code on other customer machines. Microsoft has rolled out mitigations for the vulnerability, but it is still important to upgrade self-hosted applications.
The vulnerability can occur in Self-hosted IRs as well as Azure IRs. However, Synapse workspaces can be configured to use a Managed Virtual Network, which provides more isolation for sensitive data. In addition, a Managed Virtual Network is available for Azure Data Factory customers.
Microsoft is recommending that customers update their instances of Azure Synapse and Data Factory as soon as possible. However, the patches for this vulnerability do not affect data that has already been imported into the system. Customers who already subscribe to auto-updates should be able to install the updates without any difficulty.
The vulnerability was discovered in January 2014, but Microsoft has only recently fixed it. Microsoft has since moved the vulnerable shared Synapse integration runtime to a sandbox and limited access to the management server. As a result, this vulnerability has not been exploited in the wild.
Azure Synapse Analytics supports two storage engines: Azure Data Lake Storage Gen2 and Dedicated SQL Pools. Both storage options support read-access extensions, which enable read-only access in the event of a regional or zonal outage. These features help improve data availability SLA.
In high-isolation environments, Synapse can be deployed with a Managed Virtual Network. This method allows the components of the platform to communicate with each other via private endpoints.
