This results in the potential manipulation of the statements performed on the database by the end-user of the application. The following line of code illustrates this vulnerability: However, if the "userName" variable is crafted in a specific way by a malicious user, the SQL statement may do more than the code author intended. For example, setting the "userName" variable as:
Enable auto update or ensure you are running the newest Guest OS. Azure Linux Virtual Machines Install updates from your operating system provider.
For more information, see Linux later in this document. Azure Windows Virtual Machines Install the latest security rollup. Azure automatically keeps your OS versions up-to-date. Additional guidance if you are running untrusted code Customers who allow untrusted users to execute arbitrary code may wish to implement some additional security features inside their Azure Virtual Machines or Cloud Services.
These features protect against the intra-process disclosure vectors that several speculative execution vulnerabilities describe. Example scenarios where additional security features are recommended: You allow code that you do not trust to run inside your VM.
For example, you allow one of your customers to upload a binary or script that you then execute within your application.
You allow users that you do not trust to log into your VM using low privileged accounts. For example, you allow a low-privileged user to log into one of your VMs using remote desktop or SSH. You allow untrusted users access to virtual machines implemented via nested virtualization.
For example, you control the Hyper-V host, but allocate the VMs to untrusted users.
Customers who do not implement a scenario involving untrusted code do not need to enable these additional security features. Enabling additional security You can enable additional security features inside your VM or Cloud Service. Windows Your target operating system must be up-to-date to enable these additional security features.
While numerous speculative execution side channel mitigations are enabled by default, the additional features described here must be enabled manually and may cause a performance impact.
Contact Azure Support to expose updated firmware microcode into your Virtual Machines. Follow the instructions in KB to enable protections via the Session Manager registry keys.
A reboot is required.
For deployments that are using nested virtualization D3 and E3 only: These instructions apply inside the VM you are using as a Hyper-V host. Set the hypervisor scheduler type to Core by following the instructions here.
Follow the instructions in KB to verify protections are enabled using the SpeculationControl PowerShell module. Note If you previously downloaded this module, you will need to install the newest version.
All VMs should show: True kernel VA shadow is enabled: True Linux Enabling the set of additional security features inside requires that the target operating system be fully up-to-date.
Some mitigations will be enabled by default. Enabling these features may cause a performance impact.Assessing for any database vulnerabilities, identifying compromised endpoints and classifying sensitive data.

Need access to an account? If your company has an existing Red Hat account, your organization administrator can grant you access. Introduction. This post introduces principal database vulnerabilities, providing an overview of the possible effects for their exploitation. For each database vulnerability, the principal cyber threats are exposed and a few suggestions are proposed for their mitigation.
Addresses vulnerabilities in the Active Template Libraries for the Microsoft Visual Studio that could allow remote code execution.
Applies to systems with ActiveX controls installed that were built using Visual Studio Active Template Libraries. Impact key.
Critical Vulnerability can be used to run attacker code and install software, requiring no user interaction beyond normal browsing.; High Vulnerability can be used to gather sensitive data from sites in other windows or inject data or code into those sites, requiring no more than normal browsing actions.; Moderate Vulnerabilities that would otherwise be High or Critical except they.
