"The remote NewStart CGSL host, running version MAIN 7.02, has texlive-base packages installed that are affected by a
vulnerability:

  - LuaTeX before 1.17.0 allows execution of arbitrary shell commands when compiling a TeX file obtained from
    an untrusted source. This occurs because luatex-core.lua lets the original io.popen be accessed. This also
    affects TeX Live before 2023 r66984 and MiKTeX before 23.5. (CVE-2023-32700)

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