As such all administrative, and server to database, connections are within a secured network. 1. 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 the DBSec server via carefully constructed Java serialized object sent to the DBSec server. https://web.nvd.nist.gov/view/vuln/detailvulnId=CVE-2021-23894 https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2021-23894 2. 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 the DBSec server via carefully constructed Java serialized object sent to the DBSec server. https://web.nvd.nist.gov/view/vuln/detailvulnId=CVE-2021-23895 https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2021-23895 3. 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 to DBSec data in the Insights Server. https://web.nvd.nist.gov/view/vuln/detailvulnId=CVE-2021-23896 https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2021-23896 4. 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 the DBSec interface and opens the properties configuration page for this database. https://web.nvd.nist.gov/view/vuln/detailvulnId=CVE-2021-31830 https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2021-31830 5. 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. https://web.nvd.nist.gov/view/vuln/detailvulnId=CVE-2021-31831 https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2021-31831 Remediation To remediate this issue, update to DBSec 4.8.2.

The product version displays. What is CVSS 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 at: https://www.first.org/cvss/ . When calculating CVSS scores, McAfee has 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 1.

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 McAfee If you have information about a security issue or vulnerability with a McAfee product, visit the McAfee PSIRT website for instructions at https:// www.mcafee.com/us/threat-center/product-security-bulletins.aspx . To report an issue, click Report a Security Vulnerability . How does McAfee 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 McAfee 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. McAfee only publishes 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.
