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.

Apple Mac OS X HFS Plus Local Privilege Escalation Exploit
This module exploits a vulnerability in the XNU 1228.9.59 and earlier that does not properly restrict interaction between user space and the HFS IOCTL handler, which allows local users to overwrite kernel memory and gain privileges by attaching an HFS+ disk image
This module exploits a vulnerability in Avast Antivirus ASWMON.SYS driver when handling a specially crafted IOCTL request. The vulnerability allows local users to overwrite memory and execute arbitrary code via malformed Interrupt Request Packet (Irp) parameters.
Blue Coat K9 Web Protection Referer Privilege Escalation Exploit
K9 Web Protection's local administration interface is vulnerable to a stack based buffer overflow while processing ''Referer'' HTTP headers. Local attackers could use this vulnerability to escalate privileges.
cdrecord in the cdrtools package before 2.01, when installed setuid root, does not properly drop privileges before executing a program specified in the RSH environment variable, which allows local users to gain privileges. This module exploits this vulnerability.
Stack-based buffer overflow in WINSRV.DLL in the Client Server Runtime System (CSRSS) process of Microsoft Windows 2000, Windows XP SP1 and SP2, and Windows Server 2003 allows local users to gain privileges via a specially-designed application that provides console window information with a long FaceName value.
This module exploits a vulnerability in OpenBSD crontab entries that allow arbitrary commands execution as root. To exploit the vulnerability this exploit will create an agent in the target filesystem which will be automatically executed later (with root privileges) by a crontab vulnerable security entry (/etc/daily | mail). Once the agent gets executed, it is possible to connect to it. If the exploit succeeds, a new agent will be installed with root privileges.
This module exploits a vulnerability in ElbyCDIO.SYS driver when handling a specially crafted IOCTL request. The vulnerability allows local users to overwrite memory and execute arbitrary code via malformed Interrupt Request Packet (Irp) parameters.
ESET Smart Security EPFW.SYS Privilege Escalation Exploit
This module exploits a vulnerability in ESET Smart Security EPFW.SYS driver when handling a specially crafted IOCTL request. The vulnerability allows local users to overwrite memory and execute arbitrary code via malformed Interrupt Request Packet (Irp) parameters.
The FreeBSD kernel provides support for a variety of different types of communications sockets, including IPv4, IPv6, ISDN, ATM, routing protocol, link-layer, netgraph(4), and bluetooth sockets.Some function pointers for netgraph and bluetooth sockets are not properly initialized. This can be exploited to e.g. read or write to arbitrary kernel memory via a specially crafted "socket()" system call, and allows an unprivileged process to elevate privileges to root or escape a FreeBSD jail.
This module exploits a vulnerability in FreeBSD. The FreeBSD virtual memory system allows files to be memory-mapped. All or parts of a file can be made available to a process via its address space. The process can then access the file using memory operations rather than filesystem I/O calls. Due to insufficient permission checks in the virtual memory system, a tracing process (such as a debugger) may be able to modify portions of the traced process's address space to which the traced process itself does not have write access.
Stack-based buffer overflow in sys/kern/vfs_mount.c in the kernel in FreeBSD 7.0 and 7.1, when vfs.usermount is enabled, allows local users to gain privileges via a crafted mount or nmount system call, related to copying of "user defined data" in "certain error conditions".
Improper input validation in the FreeBSD kernel's NFS client-side implementation allows local unprivileged users to escalate their privileges and execute arbitrary code with root permissions. The function nfs_mount() in file src/sys/nfsclient/nfs_vfsops.c, which is reachable from the mount and nmount system calls, employs an insufficient input validation method for copying data passed in a structure of type nfs_args from userspace to kernel. Specifically, the file handle buffer to be mounted (args.fh) and its size (args.fhsize) are completely user-controllable.
Due to spurious call to pfs_unlock() in pfs_getattr() (as defined in sys/fs/pseudofs/pseudofs_vnops.c), null pointer is dereferenced after calling extattr_get_attribute() on pseudofs vnode. By allocating page at address 0x0, attacker can overwrite arbitrarily chosen portion of kernel memory, leading to crash or local root escalation. This module exploits the vulnerability via the procfs file system, obtaining root privileges.
On Intel CPUs, sysret to non-canonical addresses causes a fault on the sysret instruction itself after the stack pointer is set to guest value but before the current privilege level (CPL) is changed. FreeBSD is vulnerable to this issue due to insufficient sanity checks when returning from a system call. This module exploits the vulnerability and installs an agent with root privileges.
FreeBSD Telnetd Server Privilege Escalation Exploit
Local attackers can exploit this issue to execute arbitrary code with superuser privileges. Successfully exploiting this issue will facilitate the complete compromise of affected computers.
The bdfReadCharacters() function in the libXfont component of X.Org is prone to a stack-based buffer overflow vulnerability when parsing a specially crafted BDF font file. This vulnerability can be exploited by a local unprivileged attacker to gain root privileges.
GNU Glibc ld.so ORIGIN Privilege Escalation Exploit
The GNU C library (GNU glibc) is prone to a local privilege-escalation vulnerability. This module exploits the vulnerability to install an agent with root privileges.
GNU ld.so Arbitrary Dlopen Privilege Escalation Exploit
The GNU C dynamic linker (ld.so) is prone to a local privilege-escalation vulnerability. This module exploits the vulnerability to create a world writable file in the /etc/cron.d directory. Then it uses the file to install an agent with root privileges. Finally the world writable file is deleted.
IBM Director CIM Server Privilege Escalation Exploit
IBM Director is prone to a privilege-escalation vulnerability that affects the CIM server. Attackers can leverage this issue to execute arbitrary code with elevated privileges in the context of the CIM server process.
There is an exploitable buffer overflow in the SSINC.DLL file used by Microsoft IIS 5.0. The problem is triggered while including long enough filenames in any ASP file. After successful exploitation an agent will be installed. The process being exploited is usually run as an IUSR or IWAM user, specially created for IIS to answer anonymous requests. If this condition is present, the newly deployed agent will run with an unprivileged user.
Libdbus 1.5.x and earlier, when used in setuid processes not clearing the environment variables, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS environment variable. This module exploits the vulnerability as present on the Xorg setuid binary and installs an agent with root privileges.
This module exploits a buffer overflow vulnerability in linuxconf. The vulnerability is due to insufficient bounds checking of the LINUXCONF_LANG environment variable.
