The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3283 advisory.

  - The OWASP ModSecurity Core Rule Set (CRS) is affected by a partial rule set bypass for HTTP multipart     requests by submitting a payload that uses a character encoding scheme via the Content-Type or the     deprecated Content-Transfer-Encoding multipart MIME header fields that will not be decoded and inspected     by the web application firewall engine and the rule set. The multipart payload will therefore bypass     detection. A vulnerable backend that supports these encoding schemes can potentially be exploited. The     legacy CRS versions 3.0.x and 3.1.x are affected, as well as the currently supported versions 3.2.1 and     3.3.2. Integrators and users are advised upgrade to 3.2.2 and 3.3.3 respectively. The mitigation against     these vulnerabilities depends on the installation of the latest ModSecurity version (v2.9.6 / v3.0.8).
    (CVE-2022-39956)

  - In ModSecurity before 2.9.6 and 3.x before 3.0.8, HTTP multipart requests were incorrectly parsed and     could bypass the Web Application Firewall. NOTE: this is related to CVE-2022-39956 but can be considered     independent changes to the ModSecurity (C language) codebase. (CVE-2022-48279)

  - Incorrect handling of '\0' bytes in file uploads in ModSecurity before 2.9.7 may allow for Web Application     Firewall bypasses and buffer overflows on the Web Application Firewall when executing rules that read the     FILES_TMP_CONTENT collection. (CVE-2023-24021)

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