Tenable Security Center Multiple Vulnerabilities (TNS-2026-19)

critical Nessus Plugin ID 328966

Synopsis

An instance of Security Center installed on the remote system is affected by multiple vulnerabilities.

Description

According to its self-reported version, the Tenable Security Center running on the remote host is between 6.6.0 and 6.8.0. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2026-19 advisory.

 - Tenable Security Center is affected by a SQL injection vulnerability. (CVE-2026-64877)

 - Double Free and possible RCE vulnerability in Apache HTTP Server with the HTTP/2 protocol. This issue affects Apache HTTP Server: 2.4.66. Users are recommended to upgrade to version 2.4.67, which fixes the issue. (CVE-2026-23918)

 - Stack buffer overflow in PostgreSQL module refint allows an unprivileged database user to execute arbitrary code as the operating system user running the database. A distinct attack is possible if the application declares a user-controlled column as a refint cascade primary key and facilitates user- controlled updates to that column. In that case, a SQL injection allows a primary key update value provider to execute arbitrary SQL as the database user performing the primary key update. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected. (CVE-2026-6637)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Apply security patch SC-202607.1 or later.
