Library of expert validated exploits for safe and effective pen tests
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. Whether written by our own internal team or by a third party like ExCraft, 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.

Linux NVIDIA exploit
The NVIDIA Binary Graphics Driver for Linux is vulnerable to a buffer overflow that allows an attacker to run arbitrary code as root.
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.
Linux Overlayfs Local Privilege Escalation Exploit
This module exploits a vulnerability in Linux. The overlayfs filesystem does not correctly check file permissions when creating new files in the upper filesystem directory. This can be exploited by an unprivileged process in kernels with CONFIG_USER_NS=y and where overlayfs has the FS_USERNS_MOUNT flag, which allows the mounting of overlayfs inside unprivileged mount namespaces.
Linux Overlayfs ovl_setattr Local Privilege Escalation Exploit
This module exploits a vulnerability in Linux. The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application.
This module exploits a vulnerability in Linux for x86_64. The IA32 system call emulation functionality does not zero extend the eax register after the 32bit entry path to ptrace is used, which might allow local users to trigger an out-of-bounds access to the system call table using the %RAX register and escalate privileges.
Linux PTRACE_TRACEME Local Privilege Escalation Exploit
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker).
Linux snapd dirty_sock Local Privilege Escalation Exploit
This module exploits a vulnerability in snapd which incorrectly validates and parses the remote socket address when performing access controls on its UNIX socket.
A local attacker could use this to access privileged socket APIs and obtain administrator privileges.
Linux snapd dirty_sock Local Privilege Escalation Exploit Update
This module exploits a vulnerability in snapd which incorrectly validates and parses the remote socket address when performing access controls on its UNIX socket.
A local attacker could use this to access privileged socket APIs and obtain administrator privileges.
A logical error in sudo when the env_reset option is disabled allows local attackers to define environment variables that were supposed to be blacklisted by sudo. This can be exploited by a local unprivileged attacker to gain root privileges by manipulating the environment of a command that the user is legitimately allowed to run with sudo.
The suid_dumpable support in Linux kernel 2.6.13 up to versions before 2.6.17.4, and 2.6.16 before 2.6.16.24, allows a local user to cause a denial of service (disk consumption) and possibly gain privileges via the PR_SET_DUMPABLE argument of the prctl function and a program that causes a core dump file to be created in a directory for which the user does not have permissions.
do_command.c in Vixie cron (vixie-cron) 4.1 does not check the return code of a setuid call, which might allow local users to gain root privileges if setuid fails in cases such as PAM failures or resource limits, as originally demonstrated by a program that exceeds the process limits as defined in /etc/security/limits.conf
The waitid implementation in upstream kernels did not restrict the target destination to copy information results. This can allow local users to write to otherwise protected kernel memory, which can lead to privilege escalation.

Lotus Notes LZH Attachment Exploit
This module exploits a buffer overflow vulnerability in Lotus Notes when parsing a malformed, specially crafted LZH file received as an email attachment.
There is a buffer overflow in lasr.dll when parsing an AMI Pro document(.sam) file. The unsafe lstrcpy() function is used to copy each line read from the file into fixed sized stack and heap buffers, with no length checks being performed. Hence, it is possible to create an AMI Pro file that contains overly long lines that will trigger the buffer overflow when viewed within Lotus Notes. In order to exploit this vulnerability successfully, the user must be convinced to view a malicious AMI Pro document file attachment using the built-in viewer in Lotus Notes.
This module exploits a buffer overflow vulnerability in Lotus Notes 8.5 when parsing a malformed, specially crafted WK3 (SpreadSheet Lotus 1-2-3 Document) file.
