CVE-2019-10091: 
Java vulnerability analysis and mitigation

Apache Geode (CVE-2019-10091) is a security vulnerability where the system fails to perform hostname verification of the entries in the certificate SAN during the SSL handshake when TLS is enabled with ssl-endpoint-identification-enabled set to true. This vulnerability was discovered in Apache Geode version 1.9.0 (NVD).

The vulnerability has been assigned a CVSS v3.1 Base Score of 7.4 (HIGH) with the vector string CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N. The vulnerability is classified under CWE-295 (Improper Certificate Validation), indicating a fundamental flaw in the certificate validation process (NVD).

The vulnerability could potentially compromise intra-cluster communication through man-in-the-middle attacks. This could lead to unauthorized access to sensitive data and potential manipulation of cluster communications (NVD).

The vulnerability requires network access and high attack complexity to exploit. While no authentication is required, the technical complexity of executing a successful attack is considered high due to the nature of TLS certificate manipulation (NVD).

Users should update to a patched version of Apache Geode. The vulnerability affects systems where TLS is enabled with ssl-endpoint-identification-enabled set to true (NVD).
