The Security Implications of an Apparent Memory Leak in the Microsoft Access Database

Published

on

In January 2019, Mimecast Research Labs discovered and disclosed CVE-2019-0560, a Microsoft Office product vulnerability. Recently the lab discovered and disclosed a startingly similar new vulnerability called MDB Leaker that required a patch (CVE-2019-1463) in Microsoft’s Access database application.

If this vulnerability is left unpatched, it could leave 85,000 companies – nearly 60% of which are in the U.S. – exposed to a leak of sensitive data.

How are these two vulnerabilities similar? Because of how a common coding mistake – in this case the improper management of system memory by an application – can lead to the unintended disclosure of sensitive or private information.

False Positives Can be Good

While false negatives such as missing malicious files or emails should always be minimized, counterintuitively, not all false positives are inherently bad. For instance, with MDB Leaker, as with the January 2019 Microsoft Office vulnerability, the report of a potential false positive proved to be critical to this discovery. Here’s how.

After receiving a false positive report for a particular Microsoft Access file flagged through static file analysis, Mimecast researchers swung into action and determined that there were code fragments in what should clearly be a data-only file type, a Microsoft Access MDB file. From there, the team suspected improperly-managed system memory in the Microsoft Access application, and they were able to reverse-engineer Microsoft Access and quickly reproduce the problem and track it back through multiple older versions of Microsoft Access.

What is the Security Vulnerability?

MDB Leaker is nearly identical to the broader Office memory leak discovered early in 2019, which causes the content of uninitiated memory elements to be saved into every file – at least since Access 2002 – that is saved with an unpatched version of Access. While in many cases, due to the randomness of memory content at play here, the data unintentionally saved into the file will often be valueless content fragments. However, this will certainly not always be true.

In some cases, the unintended data saved into the MDB file could be sensitive information such as passwords, certificates, web requests, and domain/user information. There is no way of knowing without looking! In other words, think about how a memory leak can be a security vulnerability: fundamentally, it isn’t the actual vulnerability, but it’s what the memory leak can lead to that is the actual problem.

Consider another example from researchers. If a malicious actor was able to get on a machine which contained MDB files or could get ahold of large drops of MDB files, they could conduct an automated “dumpster diving” hunt through all of them to look for and collect sensitive information residing in these files that could be applied in any number of malicious uses.

Fortunately, to date, Mimecast researchers have not seen an exploit of this vulnerability in the wild, but it is easy to presume that it will soon be added to the repertoire of malicious actors in short order. To avoid this, follow security best practices, and patch Access database executables.

How to Defend Your Organization

  • Regularly update your systems and applications for security vulnerabilities as they are patched by the vendor.
  • Once patched, consider opening and resaving existing Microsoft Access MDB files to eliminate any unwanted content that may be resident in them.
  • Use an email security system with sophisticated malware detection capabilities which includes both static file analysis as well as sandboxing to filter malicious files from entering the organization as well as sensitive content from leaving.
  • Monitor network traffic for connections to likely command-and-control services and for the exfiltration of potentially sensitive files.
  • Continuously update endpoint security system to increase the likelihood of detecting malicious software running on these hosts.

Free Mineral Water for All: UAE Startup to Launch Groundbreaking Public Hydration Initiative

Published

on

Ourwatr

Staying hydrated just got easier, and greener, thanks to Ourwatr, that’s launching a nationwide free mineral water programme starting June 2025. It’s a first in the region: clean, refreshing mineral water made freely available across the country, delivered through a unique model that blends sustainability, community care, and social impact.

From metro stations and shopping malls to parks and government offices, thousands of chilled bottles of mineral water, sourced locally from Dibba, Fujairah, will soon be within everyone’s reach, every day. Ourwatr’s mission is simple: hydration is a right, not a privilege.

“At Ourwatr, we believe that drinking water should be accessible to all,” says Abhinav Murali, Co-founder.

“That’s why we’re giving away premium mineral water for free, and every bottle supports communities in need. It’s hydration with heart, proudly made right here in the UAE.”

Stamp of UAE quality

All Ourwatr bottles carry the prestigious EQM (Emirates Quality Mark) certification, guaranteeing they meet strict UAE national and international quality standards. When you grab a bottle, you’re assured of top-quality water, safe, pure, refreshing and approved by the country’s standardisation authority.

Mission in a bottle

With temperatures rising across the UAE, especially during summer, access to clean drinking water is more important than ever, for workers, families, children, and the elderly alike.

“In our desert climate, hydration isn’t just healthy; it’s life-saving,” adds co-founder Bharath Mohan.
“Each bottle we provide is a small act of kindness toward our community.”

Ourwatr is more than just a startup, it’s a mission in a bottle. Launched by three young, UAE-based entrepreneurs, the idea was sparked by a simple but powerful observation: access to free, convenient hydration isn’t always a given.

Wanting to change that, the trio built a business with heart at its core. The team is also in talks with various UAE charitable organisations and government agencies to expand its reach and impact. For every bottle distributed, a portion will be donated to local charities, turning everyday hydration into a meaningful act of giving.

A Model Built on Purpose and Sustainability
Ourwatr isn’t just about water, it’s about doing good. Instead of selling to consumers, the company partners with brands and organisations who cover the production and distribution costs. In return, sponsors co-brand the bottles, using them as a platform to share positive messages and shared values, while making a real difference.

“Sustainability isn’t just about less waste,  it’s about creating lasting, meaningful change,” explains Sharat Nair, Co-founder.

The bottles are crafted from recyclable materials, aligning with the UAE’s zero-waste goals and green agenda.

Backing UAE Vision 2030
Ourwatr’s initiative supports the UAE’s Vision 2030 goals around health, sustainability, and quality of life. The startup is already collaborating with local authorities to expand water access and reach as many people as possible.

More than just water, Ourwatr is delivering hope, equality, and care, one bottle at a time.
