Article contents: Vulnerability Description
DBSec is designed to be installed on a private network. As such all administrative, and server to database, connections are within a secured network.
- CVE-2021-23894
Deserialization of untrusted data vulnerability in McAfee Database Security (DBSec ) prior to 4.8.2 allows a remote unauthenticated attacker to create a reverse shell with administrator privileges on theDBSec server via carefully constructed Java serialized object sent to theDBSec server.

https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23894
- CVE-2021-23895
Deserialization of untrusted data vulnerability in McAfee Database Security (DBSec ) prior to 4.8.2 allows a remote authenticated attacker to create a reverse shell with administrator privileges on theDBSec server via carefully constructed Java serialized object sent to theDBSec server.
https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-23895
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23895
- CVE-2021-23896
Cleartext Transmission of Sensitive Information vulnerability in the administrator interface of McAfee Database Security (DBSec ) prior to 4.8.2 allows an administrator to view the unencrypted password of the McAfee Insights Server used to pass data to the Insights Server. This user is restricted to only have access toDBSec data in the Insights Server.

https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23896
- CVE-2021-31830
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in McAfee Database Security (DBSec ) prior to 4.8.2 allows an administrator to embed JavaScript code when configuring the name of a database to be monitored. This would be triggered when any authorized user logs into theDBSec interface and opens the properties configuration page for this database.
https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-31830
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-31830
- CVE-2021-31831
Incorrect access to deleted scripts vulnerability in McAfee Database Security (DBSec ) prior to 4.8.2 allows a remote authenticated attacker to gain access to signed SQL scripts which have been marked as deleted or expired within the administrative console. This access was only available through the REST API.
The scripts are retained to allow them to be used when analyzing older events should they be required in the future. The impact has been judged to be low as it is expected that the scripts are created in good faith.

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?

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.
