Update December 15, 2020: This blog is updated with the FAQ section for customers to get more insight into QID details.
Original Post: Securing Java instances has become critical for organizations because Java’s wide use as an open-source component in applications has made it a captivating target for attackers.
According to a recent research, Java is the most common programming language used by developers with 90% of all Fortune 500 companies making use of the technology. It has therefore become critical for organizations to identify and secure Java installations in their environments.
Building on Qualys’ ability to discover and secure middleware technologies, a recent update to the vulnerability signature library adds discovery of Oracle Java instances in non-standard locations. Qualys now provides comprehensive visibility into all Oracle Java instances in both standard and non-standard locations, their current vulnerabilities, and what you must do to protect them.
Current Capabilities and Enhancements
One of the biggest challenges in today’s dynamic environment for security teams is identifying applications installed in non-standard locations.
The current method for discovering Java in Qualys VMDR QID signatures is based on detecting installation via the PATH environment variable. Although this approach provides customers accurate and quick discovery of a wide variety of technologies, it has limitations with respect to finding applications in non-standard locations.
With the enhanced discovery of Oracle Java instances, VMDR QID signatures add the capability to discover Oracle Java instances using OS utilities like ‘find’ (to discover Java binaries on the file system), ‘locate’, ‘whereis’, ‘which’, and ‘update-alternatives’ (to identify the system paths for Java), and by checking if a running process was started using Java. We then extract the underlying version after verifying the installation is an Oracle Java instance. The enhancement is optimized to consider timeouts so that it doesn’t negatively impact systems.
The following existing QIDs are being updated as part of this enhancement: 119956, 120274, 120443, 120443, 120604, 120799, 120832, 45188, 120879, 120970, 121061, 105490, 121279, 121515, 121712, 122007, 122362, 122741, 123168, 123519, 105618, 123714, 124169, 124567, 124882, 370087, 370161, 370280, 370371, 370469, 370610, 45285, 45286, 370727, 45301, 370887, 105750, 371079, 371265, 371528, 371749, 105801, 372013, 372163, 372333, 372508, 373156, 373540, 105412
Gain Visibility into Oracle Java Assets
Start by identifying middleware technologies running in your environment. Qualys Global IT Asset Inventory allows you to gain visibility into Oracle Java assets using hybrid data collection sensors such as network scanners and cloud agents.
Once the hosts are identified, they can be grouped together with a ‘dynamic tag’, let’s say “Oracle Java”. This automatically groups existing hosts running Oracle Java as well as any new hosts running Oracle Java that spin up in your environment. Tagging makes these grouped assets available for querying, reporting and management throughout the Qualys Cloud Platform.

Customers may also notice some older closed detections may reopen as more Oracle Java installations are discovered on their hosts.
Oracle Java QID changes are available in vulnerability signature version VULNSIGS-2.5.54-4 and above.
For customers using scanning, authenticated scanning is required to access system data used in this detection. For customers using Qualys Cloud Agent, it is required to use Cloud Agent version 2.4.0.x or later running manifest version 220.127.116.11-2 and above.
In addition, Qualys released IG QID 48157 to help customers identify which assets have Oracle Java instances running in their environment along with multiple Java instance versions on those assets.
QID 48157 : Oracle Java Version Detected
Previous Reporting of Oracle Java QID 371528
New Updated Reporting of Oracle Java QID 371528

A: The QID status will continue to follow the standard QID status workflow.
Q: What impact would this change have on Java related QIDs on assets?
A: As a part of this change, newly ran reports could show more vulnerable Oracle Java instances than earlier. Customers may also notice some older closed detections may reopen as more Oracle Java installations are discovered on their hosts.
Q: Is it likely that with the enhanced discovery, scans will take longer and customers may need to adjust their scan schedules?
A: Yes it is possible, because we run find commands to discover Java instances on non-standard locations.
Q: Would this reopen older Oracle Java related QIDs?
A: Yes, if there are vulnerable instances on the hosts.
Q: Would I see a QID posted even if I have applied the patch ?
A: QID would be posted as long as there is at least one instance of Oracle Java which is not patched.
Q: I had applied a patch for a Oracle Java QID long time ago. Why is the QID now reopened?
A: With Oracle Java Extended Discovery we were able to identify more instance on the host and found at least one Oracle Java instance that was not patched.
Q: How do I resolve the Issue?
A: Please navigate to the “Vulnerability Result” section and check for all the Oracle Java “Install Location” paths. Apply the patches for vulnerable instances to resolve this issue.
Q: Were additional CVE’s added to old Oracle Java QIDs?
A: No CVEs were added/removed from QIDs as a part of Oracle Java Extended Discovery.
Q: Why is Oracle Java Enhanced Discovery logic added now?
A: The Qualys research team is continuously looking for better ways to identify and accurately report vulnerabilities. As part of this effort, we updated Oracle Java vulnerability detection logic to give our customers better visibility into vulnerable instances of Oracle Java installed in non-standard locations.
Q: How does the new Oracle Java Enhanced Discovery logic work?
A: These are the steps:
- Discover all Java instances (including non-standard locations) on the host. The discovery of Java instances is done using commands such as ‘find’, ‘locate’, ‘whereis’, ‘which’, ‘update-alternatives’, and checking for running Oracle Java processes.
- Once Java instances are discovered on the host, vendor information (Oracle) is verified using Java lib files ex: ‘<Java_Home>/lib/rt.jar’, and more.
- Finally, the Oracle Java version is extracted from the Java binary.
Q: How do I report inaccurate results?
A: File a support request, and inform your TAM as well.
Q: How will Qualys notify customers of similar changes in future?
A: Qualys research team will implement a 15-day notification process for any bulk modification of QIDs or significant changes to underlying QID detection logic for major applications.
See all notifications: https://notifications.qualys.com
Q: Will Qualys add similar detection support for other technologies?
A: Yes. Qualys research team plans to add similar detection capabilities for other technologies. The team will provide a 15-day notification before such changes are made live. In addition to that we will allow customers to opt-in into enhanced detection capabilities in future.
