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.

Apache CouchDB Cluster Default Cookie Remote OS Command Injection Exploit
A default erlang cluster node cookie in Apache CouchDB allows attackers to access, gain admin privileges and execute system commands with couchdb user privileges.
An authentication bypass vulnerability present in com.vmware.vcops.ui.util.MainPortalFilter class, an information disclosure vulnerability present in com.vmware.vcops.ui.action.SupportLogsAction and a local privilege escalation in the generateSupportBundle.py script; allows unauthenticated remote attackers to execute system commands as root in VMware vRealize Operations Manager by using a dashboard shared link.

Impact
VMware Workspace ONE Access Hekate Remote Code Execution Exploit
An authentication bypass in OAuth2TokenResourceController access control service, a JDBC injection that allows remote code execution in DBConnectionCheckController dbCheck and a local privilege escalation via publishCaCert.hzn and gatherConfig.hzn; allows unauthenticated remote attackers to execute system commands as root.
A java deserialization vulnerability in Zoho ManageEngine Pro before 12101 and PAM360 before 5510 allows unauthenticated attackers to send crafted XML-RPC requests with malicious serialized data to execute system commands as SYSTEM.
Linux Kernel Legacy Parse Param IU HO Local Privilege Escalation Exploit
A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system
Microsoft Windows SMBv3 FileNormalizedNameInformation DoS
Microsoft Windows SMBv3 suffers from a null pointer dereference in versions of Windows prior to the April, 2022 patch set. By sending a malformed FileNormalizedNameInformation SMBv3 request over a named pipe, an attacker can cause a Blue Screen of Death (BSOD) crash of the Windows kernel. For most systems, this attack requires authentication, except in the special case of Windows Domain Controllers, where unauthenticated users can always open named pipes as long as they can establish an SMB session. Typically, after the BSOD, the victim SMBv3 server will reboot.
IBM DB2 Web Query for IBM i Log4shell Vulnerability Checker
JNDI features used in configuration, log messages, and parameters present in Apache Log4j2 do not protect against attacker controlled LDAP and other JNDI related endpoints. This library, used by IBM DB2 Web Query for IBM i, allows unauthenticated attackers to execute system commands.
Atlassian Questions for Confluence Hardcoded Credentials Vulnerability Checker
Atlassian Questions for Confluence creates a Confluence user account with the username disabledsystemuser.
The disabledsystemuser account is created with a hardcoded password and is added to the confluence-users group, which allows viewing and editing all non-restricted pages within Confluence by default
A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence and access any pages the confluence-users group has access to.
A server side request forgery present in getKeyInfoData function of oracle.security.xmlsec.keys.RetrievalMethod and a deserialization vulnerability present in the ADF Faces framework allows a unauthenticated attacker with network access via HTTP to execute system commands.
Microsoft Windows Networks File System 4.1 Remote DoS
Microsoft Windows could allow a remote attacker to execute arbitrary code or BSOD the system, caused by a design flaw in the Network File System component.
Linux Kernel Netfilter Dup Netdev OOB Write Local Privilege Escalation Exploit
net/netfilter/nf_dup_netdev.c in the Linux kernel 5.4 through 5.6.10 allows local users to gain privileges because of a heap out-of-bounds write. This is related to nf_tables_offload.
A vulnerability was discovered in RealVNC VNC Server installations on Windows when running MSI repair, which can lead to a local user privilege escalation.
Linux Kernel eBPF OR NULL Pointer Local Privilege Escalation Exploit
The bpf verifier(kernel/bpf/verifier.c) did not properly restrict several *_OR_NULL pointer types which allows these types to do pointer arithmetic. An unprivileged user could use this flaw to escalate their privileges on a system. Setting parameter "kernel.unprivileged_bpf_disabled=1" prevents such privilege escalation by restricting access to bpf(2) call.
An OGNL injection vulnerability present in ActionChainResult class of xwork jar file would allow an unauthenticated attacker to execute arbitrary code on a Confluence Server or Data Center instance.
Microsoft Windows Support Diagnostic Tool (MSDT) Remote Code Execution Exploit
This module exploits a vulnerability in Microsoft MSDT, which can be leveraged to execute arbitrary code on vulnerable machines by convincing an unsuspecting user to open a malicious document.
This update adds a new parameter to the "Ransomware Simulation" module: "RENAME FILES"; if set to TRUE, encrypted files will also be renamed by adding the .1mp4ct extension to them.
Microsoft Windows Point-to-Point Tunneling Protocol DoS
A denial of service vulnerability exists in Point-to-Point Tunneling Protocol service when an unauthenticated attacker connects to the target system and sends specially crafted requests.
This update adds a couple modules to simulate a ransomware attack in a previously exploited host. "Ransomware Simulation" to run the simulated ransomware attack. "Files Decryption after Ransomware Simulation" to decrypt previously encrypted files.
