"The version of Delta DOPSoft installed on the remote host is prior to or equal to 2.00.07. It is, therefore, affected
by multiple vulnerabilities as referenced in the CISA ICSA-21-252-02 advisory.

  - Delta Electronic DOPSoft 2 (Version 2.00.07 and prior) lacks proper validation of user-supplied data when
    parsing specific project files. This could lead to a stack-based buffer overflow while trying to copy to a
    buffer during font string handling. An attacker could leverage this vulnerability to execute code in the
    context of the current process. (CVE-2021-38402)

  - Delta Electronic DOPSoft 2 (Version 2.00.07 and prior) lacks proper validation of user-supplied data when
    parsing specific project files. This could result in a heap-based buffer overflow. An attacker could
    leverage this vulnerability to execute code in the context of the current process. (CVE-2021-38404)

  - Delta Electronic DOPSoft 2 (Version 2.00.07 and prior) lacks proper validation of user-supplied data when
    parsing specific project files. This could result in multiple out-of-bounds write instances. An attacker
    could leverage this vulnerability to execute code in the context of the current process. (CVE-2021-38406)

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