The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3293 advisory.

  - A SQL injection bypass (aka PL1 bypass) exists in OWASP ModSecurity Core Rule Set (owasp-modsecurity-crs)     through v3.1.0-rc3 via {`a`b} where a is a special function name (such as if) and b is the SQL statement     to be executed. (CVE-2018-16384)

  - Modsecurity owasp-modsecurity-crs 3.2.0 (Paranoia level at PL1) has a SQL injection bypass vulnerability.
    Attackers can use the comment characters and variable assignments in the SQL syntax to bypass Modsecurity     WAF protection and implement SQL injection attacks on Web applications. (CVE-2020-22669)

  - OWASP ModSecurity Core Rule Set 3.1.x before 3.1.2, 3.2.x before 3.2.1, and 3.3.x before 3.3.2 is affected     by a Request Body Bypass via a trailing pathname. (CVE-2021-35368)

  - The OWASP ModSecurity Core Rule Set (CRS) is affected by a partial rule set bypass by submitting a     specially crafted HTTP Content-Type header field that indicates multiple character encoding schemes. A     vulnerable back-end can potentially be exploited by declaring multiple Content-Type charset names and     therefore bypassing the configurable CRS Content-Type header charset allow list. An encoded payload can     bypass CRS detection this way and may then be decoded by the backend. 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 to upgrade to 3.2.2 and 3.3.3 respectively. (CVE-2022-39955)

  - 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)

  - The OWASP ModSecurity Core Rule Set (CRS) is affected by a response body bypass. A client can issue an     HTTP Accept header field containing an optional charset parameter in order to receive the response in an     encoded form. Depending on the charset, this response can not be decoded by the web application     firewall. A restricted resource, access to which would ordinarily be detected, may therefore bypass     detection. 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 to upgrade to 3.2.2 and 3.3.3 respectively.
    (CVE-2022-39957)

  - The OWASP ModSecurity Core Rule Set (CRS) is affected by a response body bypass to sequentially exfiltrate     small and undetectable sections of data by repeatedly submitting an HTTP Range header field with a small     byte range. A restricted resource, access to which would ordinarily be detected, may be exfiltrated from     the backend, despite being protected by a web application firewall that uses CRS. Short subsections of a     restricted resource may bypass pattern matching techniques and allow undetected access. 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 to upgrade to 3.2.2 and 3.3.3 respectively and to configure a CRS     paranoia level of 3 or higher. (CVE-2022-39958)

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

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)
