Osmedeus – A Workflow Engine for Offensive Security
Osmedeus by J3ssie, is a Workflow Engine for Offensive Security. It was designed to build a foundation with the capability and flexibility that allow you to automatic your reconnaissance methodology on a large number of targets.
Performing Bug Bounty or Pentesting against huge companies with many indexed pages requires a special technique, experienced bug bounty hunters create their own methodologies that consist of the way they think of building a tool with speed, less false positives and more accurate results done in the way its coded. This tool, automated all these techniques and lets you focus on the findings and results which is what goes down to at the end. It combines some of the most used bug bounty tools into one whole workflow automated system ready to go! The Engine has successfully found a tremendous number of security vulnerabilities in many big companies out there with its unique reconnaissance methodology such as: Google, Microsoft, Starbucks, Apple, Netflix, PayPal and many more! FeaturesThis latest V4 Release written in GO brings outstanding new features such as:
-Better Architecture
-Faster, Stable and More Flexible
-Easier to Customize and Extend
-Auto Clean Junk Output and Backup
-Cloud Distributed Scans
-Synchronize data across machines

Partially Unpatched VMware Bug Opens Door to Hypervisor Takeover
https://www.blackhatethicalhacking.com/wp-content/uploads/2021/08/Untitled-design-2-1.png Partially Unpatched VMware Bug Opens Door to Hypervisor TakeoverPost Views: 162 https://www.blackhatethicalhacking.com/wp-content/uploads/2021/08/BECOME-A-PATRON-AND-UNLOCK-EXCLUSIVE-VIDEOS-1.png Reading Time: 2 Minutes
A security vulnerability in VMware’s Cloud Foundation, ESXi, Fusion and Workstation platforms could pave the way for hypervisor takeover in virtual environments – and a patch is still pending for some users.
The issue affects a wide swath of the virtualization specialist’s portfolio and affects Windows, Linux and Mac users. Details about the platforms:
* Cloud Foundation is VMware’s multicloud management platform, providing software-defined services for compute, storage, network, security, Kubernetes and so on.
* ESXi is a bare-metal hypervisor that installs on a server and partitions it into multiple virtual machines (VMs).
* Fusion is a software hypervisor that allows Intel-based Macs to run VMs with guest operating systems – such as Microsoft Windows, Linux, NetWare, Solaris or macOS.
* Workstation enables users to set up VMs on a single physical machine.
The bug (CVE-2021-22045) is a high-severity heap-overflow vulnerability carrying a CVSS rating of 7.7 out of 10. Heap overflows are memory issues that can result in data corruption or unexpected behavior by any process that accesses the affected memory area – in some cases resulting in remote code execution (RCE).
In this case, the problem specifically exists in the CD-ROM device emulation function of the affected products.
“A malicious actor with access to a virtual machine with CD-ROM device emulation may be able to exploit this vulnerability in conjunction with other issues, to execute code on the hypervisor from a virtual machine,” the vendor noted in its advisory. “Successful exploitation requires a CD image to be attached to the virtual machine.”

Reno Robert, senior vulnerability researcher for Trend Micro’s Zero Day Initiative, told Threatpost that the issue results from “the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer.” Complex but Dangerous ExploitationRobert added that even though the bug allows an untrusted guest OS user to execute code on the hypervisor, “an attacker would not have control over the data written, so exploitation this would be difficult.”
Hence the need to be used “in conjunction with other issues.” Reno explained that an example of other issues “could be an information-disclosure vulnerability that provide details on the memory layout. This would making exploitation more feasible.”
If successful though, attackers could compromise the host operating system of the hypervisor. Taking over a hypervisor, which is the highly privileged software that creates and runs VMs and governs how resources are shared among them (such as memory and processing), can give cybercriminals a clear path to accessing any of the data or applications stored in the VMs it controls, and executing code or installing files on those VMs, depending on the security controls that are implemented.
Researcher “Jaanus K\xc3\xa4\xc3\xa4p” with Clarified Security and Trend Micro’s ZDI were credited with discovering the bug.

Reno Robert, senior vulnerability researcher for Trend Micro’s Zero Day Initiative, told Threatpost that the issue results from “the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer.” Complex but Dangerous ExploitationRobert added that even though the bug allows an untrusted guest OS user to execute code on the hypervisor, “an attacker would not have control over the data written, so exploitation this would be difficult.”
Hence the need to be used “in conjunction with other issues.” Reno explained that an example of other issues “could be an information-disclosure vulnerability that provide details on the memory layout. This would making exploitation more feasible.”
If successful though, attackers could compromise the host operating system of the hypervisor. Taking over a hypervisor, which is the highly privileged software that creates and runs VMs and governs how resources are shared among them (such as memory and processing), can give cybercriminals a clear path to accessing any of the data or applications stored in the VMs it controls, and executing code or installing files on those VMs, depending on the security controls that are implemented.
Researcher “Jaanus K\xc3\xa4\xc3\xa4p” with Clarified Security and Trend Micro’s ZDI were credited with discovering the bug.
