Vulnerability Description
This release addresses multiple issues affecting MA for Linux, macOS, and
Windows.
o CVE-2022-1256 affects MA for Windows, with local access as a low privileged
user required.
o CVE-2022-1257 affects the agent for Linux, macOS, and Windows through the
way sensitive information is stored on the endpoint.
o CVE-2022-1258 requires the ePO extension to be updated, with the update
remediating for agents installed on any of the supported operating systems.
1. CVE-2022-1256
A local privilege escalation vulnerability in MA for Windows prior to 5.7.6
allows a local low privileged user to gain system privileges through
running the repair functionality. Temporary file actions were performed on
the local user's %TEMP% directory with System privileges through
manipulation of symbolic links.
NVD CVE-2022-1256
MITRE CVE-2022-1256
2. CVE-2022-1257
Insecure storage of sensitive information vulnerability in MA for Linux,
macOS, and Windows prior to 5.7.6 allows a local user to gain access to
sensitive information through storage in ma.db . The sensitive information
has been moved to encrypted database files.
NVD CVE-2022-1257
MITRE CVE-2022-1257
3. CVE-2022-1258
A blind SQL injection vulnerability in the ePolicy Orchestrator (ePO)
extension of MA prior to 5.7.6 can be exploited by an authenticated
administrator on ePO to perform arbitrary SQL queries in the back-end
database, potentially leading to command execution on the server.
NVD CVE-2022-1258
MITRE CVE-2022-1258
Remediation
To remediate this issue, customers should update to the MA 5.7.6 April 2022

KB52634 - How to determine what hotfix is installed for ePO .
o Create a query in ePO for the product version of the product installed
within your organization.
What is CVSS
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 adopt 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.

Where can I find a list of all Security Bulletins
All Security Bulletins are published on our external PSIRT website . To see
Security Bulletins, click Enterprise Security Bulletins . 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,
go to the PSIRT website , click Report a Security Vulnerability , and follow
the instructions.
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 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.
