CVE-2021-23895: 
McAfee Database Security vulnerability analysis and mitigation

CVE-2021-23895 is a deserialization of untrusted data vulnerability discovered in McAfee Database Security (DBSec) versions prior to 4.8.2. The vulnerability was disclosed in June 2021 and affects McAfee Database Security systems. This security flaw allows remote authenticated attackers to create a reverse shell with administrator privileges on the DBSec server (MITRE, NVD).

The vulnerability is classified under CWE-502 (Deserialization of Untrusted Data). The attack vector involves sending a carefully constructed Java serialized object to the DBSec server, which when processed by the application, leads to unauthorized privilege escalation (MITRE).

When successfully exploited, the vulnerability allows attackers to establish a reverse shell with administrator privileges on the affected DBSec server, potentially leading to complete system compromise (MITRE).

The vulnerability has been addressed in McAfee Database Security version 4.8.2. Organizations running affected versions should upgrade to version 4.8.2 or later to mitigate this security risk (NVD).
