Exploit development can be an advanced penetration testing skill that takes time to master. Additionally, when on a job, pen testers often don’t have the resources to create a new exploit. Many resort to searching for and using pre-written exploits that have not been tested and must go through the timely effort of quality assurance testing in order to ensure they are secure and effective.
Core Impact users can save time by finding all the up-to-date exploits they need in one place. We provide a robust library of exploits designed to enable pen testers to safely and efficiently conduct successful penetration tests. Witten by our own internal team, you can trust they have been thoroughly tested and validated by our experts.
The universe of vulnerabilities is huge and not all of them represent the same risk for the customers. Vulnerabilities do not all have the same level of criticality. Some may be easily exploitable by a low-level user, while others may not be exploitable at all. To increase the efficiency of the attacks and the quality of the exploits provided, the Core Impact team has developed selection criteria to prioritize its analysis and implementation. We determine which exploits warrant creation based on the following questions:
What are the most critical attacks from the attacker’s perspective?
What new vulnerabilities are more likely to be exploited in real attacks?
What exploits are the most valuable for Core Impact?
Once an exploit is approved, its priority order considers the following variables:
Vulnerability Properties: CVE, disclosure date, access mechanism and privileges needed.
Target Environment Setup: OS, application prevalence, version and special configurations needed.
Value Provided to Core Impact: Customer request, usage in multiple attacks, allows the installation of an agent, etc.
Technical Cost vs. Benefit: An analysis weighing the resources needed to build an exploit with the internal and external knowledge gained in its creation.
Each one of these variables has a different weight and provides a ranking of the potential exploits to be developed. Following those criteria, the top of the list would contain, for example, a vulnerability on Windows (most popular OS) that can be exploited remotely, without authentication and that provides super user privileges.
Correspondingly, a vulnerability on an application that is rarely installed, needs special configurations, and requires User Interaction, would be at the bottom.

Product Name
Linux Kernel eBPF OOB Read Write ALU32 Local Privilege Escalation Exploit
The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e ("bpf: Fix alu32 const subreg bound tracking on bitwise operations") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37.
MSI Dragon Center Local Privilege Escalation Exploit
The MsIo64.sys driver before 1.1.19.1016 in MSI Dragon Center exposes functionality that allows low-privileged users to interact with the device and exploit a stack buffer overflow via specially crafted IOCTL requests and elevate system privileges.
This module exploits a JSON deserialization vulnerability present in the test alert actions of SolarWinds Orion Network Performance Monitor. The deployed agent will run with the privileges of the "IIS Worker Process" process (NT AUTHORITY\NETWORK SERVICE).
Microsoft Windows Print Spooler PrintNightmare Remote Code Execution Exploit
The vulnerability has been dubbed PrintNightmare and is tracked as CVE-2021-34527. The flaw is due to the Windows Print Spooler service improperly performing privileged file operations. Microsoft says the flaw can be exploited by an authenticated user calling RpcAddPrinterDriverEx(). When exploited, an attacker gains SYSTEM privileges and can execute arbitrary code, install programs, view, change, or delete data or create new accounts with full user rights.
A vulnerability in Pulse Connect Secure could allow an authenticated administrator to perform a file write via a maliciously crafted archive uploaded in the administrator web interface. The deployed agent will run with ROOT privileges.
Microsoft Windows Print Spooler PrintNightmare Local Privilege Escalation Exploit
A Local Privilege Escalation vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges.
Cisco AnyConnect Posture Security Service TOCTOU Local Privilege Escalation Exploit
The Security Service of Cisco AnyConnect Posture (HostScan) for Windows incorrectly restricts access to internal IPC commands. This could enable low-privileged users to achieve NT AUTHORITY\SYSTEM privileges by sending crafted IPC commands. This module bypasses CVE-2021-1366 by abusing a Time-of-check Time-of-use (TOCTOU) Race Condition in the priv_file_copy command.
Linux OverlayFS Attr Local Privilege Escalation Exploit
The overlayfs implementation in the linux kernel did not properly validate with respect to user namespaces the setting of file capabilities on files in an underlying file system. Due to the combination of unprivileged user namespaces along with a patch carried in the Ubuntu kernel to allow unprivileged overlay mounts, an attacker could use this to gain elevated privileges.
This module first uses hard-coded credentials for the diagnostics user to authenticate in the UCMDB component. Then a java deserialization vulnerability present in several endpoints of the UCMDB service is used to execute commands. The deployed agent will run with the SYSTEM privileges on Windows and root on Linux.
A vulnerability in the admin web interface could allow an authenticated attacker to upload a custom template to perform an arbitrary code execution. These templates can be used to display customised login and meeting pages and are rendered using the Perl Template Toolkit engine. This engine can be coerced into executing code by creating a new "BLOCK" by abusing the "template" global object to create a new block to be evaluated. The deployed agent will run with ROOT privileges.
Cisco AnyConnect Posture Security Service Local Privilege Escalation Exploit
Multiple vulnerabilities in Cisco AnyConnect Posture for Windows could allow an authenticated local attacker, to execute arbitrary commands with SYSTEM user privileges.
FreeBSD Sendmsg Compat32 Local Privilege Escalation Exploit
This module exploits a vulnerability in FreeBSD. The sendmsg system call in the compat32 subsystem on 64-bit platforms has a time-of-check to time-of-use vulnerability allowing a mailcious userspace program to modify control message headers after they were validation.
Microsoft Windows Print Spooler Service Arbitrary File Write Elevation of Privilege Vulnerability Exploit (CVE-2020-1337)
An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly allows arbitrary writing to the file system bypassing CVE-2020-1048.
