Article contents:
This release addresses two ePO product code vulnerabilities and updates three libraries that ePO uses. The third-party libraries are listed, as we have received a number of queries from customers asking about our status. Third-party libraries are updated regularly and only called out in Security Bulletins if we receive a significant number of queries.
The third-party libraries updated in this release are as follows:
To remediate this issue, customers using ePO 5.10 should update to ePO 5.10 Update 14.

Frequently Asked Questions (FAQs)
How do I know if my product is vulnerable or not?
For ePO/server products:
Use the following instructions for server-based products:
Common Vulnerability Scoring System (CVSS) is the result of the National Infrastructure Advisory Council's effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to determine how critical a vulnerability is and plan accordingly. For more information, visit the CVSS website.
When calculating CVSS scores, we've adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We don't factor into a score any potential follow-on exploits that might be made possible by the successful exploitation of the issue being scored.
What are the CVSS scoring metrics?
All Security Bulletins are published on our Knowledge Center. Security Bulletins are retired (removed) once a product is both End of Sale and End of Support (End of Life).
How do I report a product vulnerability to you?
If you have information about a security issue or vulnerability with a product, follow the instructions provided in KB95563 - Report a vulnerability.
How do you respond to this and any other reported security flaws?
Our key priority is the security of our customers. If a vulnerability is found within any of our software or services, we work closely with the relevant security software development team to ensure the rapid and effective development of a fix and communication plan.
We only publish Security Bulletins if they include something actionable such as a workaround, mitigation, version update, or hotfix. Otherwise, we would simply be informing the hacker community that our products are a target, putting our customers at greater risk. For products that are updated automatically, a non-actionable Security Bulletin might be published to acknowledge the discoverer.

This release addresses two ePO product code vulnerabilities and updates three libraries that ePO uses. The third-party libraries are listed, as we have received a number of queries from customers asking about our status. Third-party libraries are updated regularly and only called out in Security Bulletins if we receive a significant number of queries.
The third-party libraries updated in this release are as follows:
- Java has been updated to the July 2022 update (1.8.0_345).
Details on the CVEs published by Java are in the Java Security Advisory.
- Apache HTTP Server has been updated to 2.4.54.
Apache Security Advisory
For other Apache HTTP Server CVEs that don't impact ePO, see KB94982 - ePolicy Orchestrator documentation for Apache CVEs.
- OpenSSL has been updated to 1.0.2.zf. We have a support agreement with the maintainers of OpenSSL and receive security updates on 1.0.2.
OpenSSL Security Advisory
- CVE-2022-3338
An External XML entity (XXE) vulnerability in ePO prior to 5.10 Update 14 can lead to an unauthenticated remote attacker to potentially trigger a Server Side Request Forgery attack. This can be exploited by mimicking the Agent Handler call to ePO and passing the carefully constructed XML file through the API.
NIST CVE-2022-3338
MITRE CVE-2022-3338
To exploit this XXE, the attacker would have to reverse engineer the ePO XML format and then use detailed knowledge of the ePO server's internal structure to exploit it. The Data channel extension isn't installed by default.
- CVE-2022-3339
A reflected cross-site scripting (XSS) vulnerability in ePO prior to 5.10 Update 14 allows a remote unauthenticated attacker to potentially obtain access to an ePO administrator's session by convincing the authenticated ePO administrator to click on a carefully crafted link. This would lead to limited access to sensitive information and limited ability to alter some information in ePO.
NIST CVE-2022-3339
MITRE CVE-2022-3339
To remediate this issue, customers using ePO 5.10 should update to ePO 5.10 Update 14.

Frequently Asked Questions (FAQs)
How do I know if my product is vulnerable or not?
For ePO/server products:
Use the following instructions for server-based products:
- Check the version and build of ePO that's installed. For instructions, see KB52634 - How to determine what hotfix is installed for ePO.
- Create a query in ePO for the product version of the product installed within your organization.
