This Security Bulletin contains details of vulnerabilities discovered in the ePO code base and in third-party libraries. They range in severity from Low to High and we recommend you update to the latest ePO version.
Third-party libraries:
Tomcat
- CVE-2020-13935
The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service.
- CVE-2020-9484
When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed.

These issues only affect the on-premises version of ePO.
- CVE-2020-7317
Cross-Site Scripting vulnerability in ePolicy Orchestrator (ePO) prior to 5.10.9 Update 9 allows administrators to inject arbitrary web script or HTML via parameter values for "syncPointList" not being correctly sanitized.
- CVE-2020-7318
Cross-Site Scripting vulnerability in ePolicy Orchestrator (ePO) prior to 5.10.9 Update 9 allows administrators to inject arbitrary web script or HTML via multiple parameters where the administrator's entries were not correctly sanitized.
To remediate this issue:
- Customers using ePO 5.10: Update to ePO 5.10.0 Update 9.
- Customers using ePO 5.9.1 and earlier: Do either of the following:
- Upgrade to ePO 5.10.0 Update 9 to receive fixes for the Java, Tomcat, and XSS issues.
- Upgrade to ePO 5.9.1 (if not on it already) and apply ePO 5.9.1 Hotfix EPO-919400 to receive fixes for only the Java and Tomcat issues.
NOTE: ePO 5.9.1 Hotfix EPO-919400 does not address the XSS issue applicable to ePO 5.9.1 (CVE-2020-7317). To remediate this low risk issue, upgrade to ePO 5.10 Update 9.
| Product | Version | Type | Release Date |
| ePO | 5.10.0 Update 9 | Update | October 13, 2020 |
| ePO | 5.9.1 EPO-919400 | Hotfix | November 10, 2020 |

Frequently Asked Questions (FAQs)
How do I know if my product is vulnerable?
For ePO/server products:
Use the following instructions for server-based products:
- Check the version and build of ePO that is installed. For information about how to check the version, see KB52634.
- Create a query in ePO for the product version of the product installed within your organization.
CVSS, or Common Vulnerability Scoring System, 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 judge 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 do not 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?
- CVE-2020-7317: ePO Cross-Site Scripting vulnerability

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.
To view our PSIRT policy, see KB95564 - About PSIRT.
