    CVE ID         : CVE-2021-33178 CVE-2022-3979 CVE-2022-46945 CVE-2023-46287
                     CVE-2024-13722 CVE-2024-13723 CVE-2024-47093

    Multiple vulnerabilities were discovered in nagvis, a visualization
    addon for Nagios or Icinga.

    CVE-2021-33178

       Due to an authenticated path traversal vulnerability, a malicious actor
       has the ability to arbitrarily delete files on the local system.

    CVE-2022-3979

       Due to a type juggling vulnerability, a remote attacker could
       successfully guess an authentication cookie.

    CVE-2022-46945

       An attacker can read arbitrary files.

    CVE-2023-46287

       A XSS vulnerability exists in a function.

    CVE-2024-13722 / CVE-2024-47093

       Multiple XSS vulnerabilities exist.

    CVE-2024-13723 / CVE-2024-47093

       Multiple RCE vulnerabilities exist. An authenticated attacker with
       administrative level privileges is able to upload a malicious PHP file
       and modify specific settings to execute the contents of the file as
       PHP.

    For Debian 11 bullseye, these problems have been fixed in version
    1:1.9.25-2+deb11u1.

    We recommend that you upgrade your nagvis packages.
