Understanding the Datalake

...

The Armor data lake is a centralized repository for storing Armor collected data. With regards to vulnerabilities, the data lake contains all the data for every report created for an environment and all the historical data from when the reports are run. This can be a lot of data so narrowing down the scope of information is critical to making sense of it all.

Accessing the Datalake

...

Users can access the Datalake in two ways:

...

titleOption 2: Log Search in AMP

  1. Select a Report from the Report List and click the report name to access the details.

  2. Copy its unique report Id by navigating into the report's detail page.

  3. Navigate to Security -> Log Search and SSO into Chaos Search.

  4. Create a filter by doing the following:

    1. Click on Add filter.

    2. In Field select event.ReportId

    3. Select is for Operator.

    4. Paste the report Id from the report details page into the Value field.

    5. Click Save.

  5. Now set the date range to encompass the report date or dates to show and click Refresh.

Amazon Linux Security Advisory for e2fsprogs: ALAS2-2020-1509

vulnerability.diagnosis

&lt;DIV&gt; Issue Overview: <P>An exploitable code execution vulnerability exists in the quota file functionality of E2fsprogs 1.45.3. A specially crafted ext4 partition can cause an out-of-bounds write on the heap, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability. (<A HREF="https://access.redhat.com/security/cve/CVE-2019-5094" TARGET="_blank">CVE-2019-5094 </A>)</P><P>A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.
