United Nations data breach exposed over 100k UNEP staff records

Today, researchers have responsibly disclosed a security vulnerability by exploiting which they could access over 100,000 private employee records of United Nations Environmental Programme (UNEP).

The data breach stemmed from exposed Git directories and credentials, which allowed the researchers to clone Git repositories and gather a large amount of personally identifiable information (PII) associated with UNEP employees.

Git directory exposed WordPress DB and Git credentials

Ethical hacking and security research group Sakura Samurai have now disclosed their findings on a vulnerability that let them access over 100,000 private records of United Nations Environment Programme (UNEP) employees.

The documents and screenshots shared with BleepingComputer provide extensive details on the nature of this security flaw and all that it exposed.

Having come across the United Nation’s Vulnerability Disclosure Program and InfoSec Hall of Fameresearchers Jackson Henry, Nick Sahler, John Jackson, and Aubrey Cottle of Sakura Samurai set out to hunt for any security flaws impacting UN systems.

They then came across exposed Git directories (.git) and Git credential files (.git-credentials) on domains associated with the UNEP and United Nation’s International Labour Organization (ILO).

The researchers were able to dump the contents of these Git files and clone entire repositories from the *.ilo.org and *.unep.org domains using git-dumper.

The .git directory contents comprised sensitive files, such as WordPress configuration files (wp-config.php) exposing the administrator’s database credentials.

Likewise, different PHP files exposed as a part of this data breach contained plaintext database credentials associated with other online systems of the UNEP and UN ILO.

In addition, the publicly accessible .git-credentials files enabled the researchers to get their hands on UNEP’s source code base.

Exfiltrated data contains over 100,000 employee records

Using these credentials, researchers were able to exfiltrate over 100,000 UN employee records from multiple systems.

The data set obtained by the group exposed travel history of UN staff, with each row containing: Employee ID, Names, Employee Groups, Travel Justification, Start and End Dates, Approval Status, Destination, and the Length of Stay.

Likewise, other UN databases accessed by the researchers as a part of their analysis exposed HR demographic data (nationality, gender, pay grade) on thousands of employees, project funding source records, generalized employee records, and employment evaluation reports.

In an email interview with BleepingComputer, the group said:

“When we started researching the UN, we didn’t think it would escalate so quickly. Within hours, we already had sensitive data and had identified vulnerabilities. Overall, in less than 24 full hours we obtained all of this data,” Sakura Samurai told BleepingComputer.

“In total, we found 7 additional credential-pairs which could have resulted in unauthorized access of multiple databases. We decided to stop and report this vulnerability once we were able to access PII that was exposed via Database backups that were in the private projects,” state the researchers in their blog post.

Threat actors likely already accessed the data

The researchers shared a series of emails with BleepingComputer that showed they had originally reported the vulnerability to UN privately on January 4th, 2021.

UN Office of Information and Communications Technology (OICT) initially acknowledged their report, but, without realizing the vulnerability concerned UNEP, responded:

“The reported vulnerability does not pertain to the United Nations Secretariat, and is for ILO (International Labour Organization),” according to the emails seen by BleepingComputer, and something the UN is known to do in the past.

Eventually, according to these emails, Saiful Ridwan, Chief of Enterprise Solutions at UNEP thanked the researchers for their vulnerability report while stating that their DevOps team had taken immediate steps to patch the vulnerability and that an impact assessment of this vulnerability was in progress.

Further, in a follow-up email to researchers, seen by BleepingComputer, UNEP stated that a data breach disclosure notice was in the works but that it was “challenging as we have not done this before.”

Overall, the researchers told BleepingComputer, United Nations was quick to patch this security issue within under a week.

“Honestly, I commend Saiful for the quick fixes. Even though he stated that this was fairly new to him, they patched in record speed and secured the data.”

“At this point, our only concern is informing the affected users. Particularly, Aubrey Cottle A.K.A. Kirtaner had noted that if it was this easy to obtain the data, threat actors likely already have the data.

“The group was in agreement that the UNEP should analyze the trajectory of the exposed PII to determine how many threat actors, if any, have the data,” Sakura Samurai founder John Jackson told BleepingComputer.

This is not the first time UN systems have suffered a data breach.

In 2019, the UN did not disclose a cyberattack that had severely compromised their networks and databases.

In 2020, a disclosure finally came out from the UN which pinned the blame for the hack on a SharePoint vulnerability.

BleepingComputer reached out to UNEP for comment and we were told, “Thank you for informing us about this issue. We are contacting our experts and colleagues and we will revert as soon as we have the relevant information.”

We are awaiting further response from UNEP.
