The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:4629 advisory.

  - apr: integer overflow/wraparound in apr_encode (CVE-2022-24963)

  - httpd: mod_proxy_ajp: Possible request smuggling (CVE-2022-36760)

  - httpd: mod_proxy: HTTP response splitting (CVE-2022-37436)

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

The version of mod_security installed on the remote host is prior to 2.9.7-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2098 advisory.

  - 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 over-reads on the Web Application Firewall when executing rules that read the     FILES_TMP_CONTENT collection. (CVE-2023-24021)

This Solaris system is missing necessary patches to address critical security updates :

According to the versions of the mod_security package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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 over-reads on the Web Application Firewall when executing rules that read the     FILES_TMP_CONTENT collection. (CVE-2023-24021)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6370-1 advisory.

  - ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with     nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests.
    Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes     for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly     vulnerable: the affected versions include 2.8.0 through 2.9.4. (CVE-2021-42717)

  - 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 over-reads on the Web Application Firewall when executing rules that read the     FILES_TMP_CONTENT collection. (CVE-2023-24021)
