Team82 has made freely available a tool called AccessDB Parser
The Python-based AccessDB Parser supports software testing, fuzzing, research, and other activities
It supports Microsoft Access versions 1995 up to 2010
Team82 today shares AccessDB Parser, a new, purpose-built tool we developed to support activities such as testing, automation, fuzzing, and reverse-engineering research, among others. The standalone tool—which can be used to quickly parse through Microsoft AccessDB files (.mdb/.accdb)—is fully written in Python, thus eliminating any external binary dependencies.
Our parser supports Microsoft Access versions 1995 up to 2010. Microsoft Access is a database management system from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface (GUI) and software-development tools. It is a member of the Microsoft Office suite of applications, included in the Professional and higher editions or sold separately.
According to Claroty Researcher Uri Katz, who led the development of AccessDB Parser, the initial purpose of the tool was to support Claroty Continuous Threat Detection (CTD)'s Application DB (AppDB) scanning capabilities. Unique to Claroty, AppDB provides a safe, effective, and non-intrusive method for identifying and managing assets in operational technology (OT) environments by parsing artifacts such as programmable logic controller (PLC) and remote terminal unit (RTU) project configuration files.
As part of Claroty's efforts to deliver the highest level of visibility into OT environments, we sought to develop a tool that would allow AppDB to process additional types of SCADA project files containing .mdb files. In addition, we wanted this tool to allow us to create multiple tests, verify test results, and automate some of our testing processes.
To address these needs, we decided to invest time in developing our own parsing tool, below, which could easily be modified and improved on an ongoing basis as our needs evolve. We ensured to make the tool open-source, knowing that it would likely prove useful for other reverse engineers.
C Implementation: Our library of tools relies heavily on the well-documented work of mdb-tools, which can be accessed here.
Java Implementation: We also benefited greatly from Jackcess, an all-Java library for reading from and writing to MS Access databases, currently supporting versions 2000-2016. Jackcess is not an application and does not have a GUI. Rather, it is intended to help developers build Java applications.
OLE fields are currently not supported.
Only a subset of memo fields are parsed.
This library was tested on a limited subset of database files. Due to the differences between database versions and the complexity of the parsing, we expect to find more parsing edge-cases.
To help us resolve issues faster, please provide as much data as possible when opening an issue, including the DB file if possible, as well as full trace, including log messages.

CWE-121 STACK-BASED BUFFER OVERFLOW:
Affected Vertiv products contain a stack based buffer overflow vulnerability. An attacker could exploit this vulnerability to gain code execution on the device.
Vertiv recommends users take the following actions:
CVSS v3: 9.8
CWE-288 AUTHENTICATION BYPASS USING AN ALTERNATE PATH OR CHANNEL:
Affected Vertiv products do not properly protect webserver functions that could allow an attacker to bypass authentication.
Vertiv recommends users take the following actions:
CVSS v3: 9.8
CWE 287: Improper Authentication
An Improper Authentication vulnerability exists in Danfoss AK-SM8xxA Series, resulting in an authentication bypass. Install the latest patch with number 4.2 to remediate this vulnerability. This flaw could enable an attacker to generate a web report that discloses sensitive information such as internal IP addresses, usernames, store names, and other sensitive information.e
CVSS v3: 8.2
CWE-798 USE OF HARD-CODED CREDENTIALS:
In Optigo Networks ONS NC600 versions 4.2.1-084 through 4.7.2-330, an attacker could connect with the device's ssh server and utilize the system's components to perform OS command executions.
Optigo Networks recommends users implement at least one of the following additional mitigations:
CVSS v3: 9.8
CWE-78 Improper Neutralization of Special Elements used in an OS Command:
A remote unauthenticated attacker who has bypassed authentication could execute arbitrary OS commands to disclose, tamper with, destroy or delete information in Mitsubishi Electric smartRTU, or cause a denial-of service condition on the product.
Mitsubishi Electric Europe B.V. recommends that users take note of the following mitigation measures to minimize the risk of exploiting this vulnerability:
CVSS v3: 9.8
