"The remote NewStart CGSL host, running version MAIN 7.02, has busybox packages installed that are affected by multiple
vulnerabilities:

  - BusyBox through 1.35.0 allows remote attackers to execute arbitrary code if netstat is used to print a DNS
    PTR record's value to a VT compatible terminal. Alternatively, the attacker could choose to change the
    terminal's colors. (CVE-2022-28391)

  - A heap-buffer-overflow was discovered in BusyBox v.1.36.1 in the next_token function at awk.c:1159.
    (CVE-2023-42366)

  - In tar in BusyBox through 1.37.0, a TAR archive can have filenames hidden from a listing through the use
    of terminal escape sequences. (CVE-2025-46394)

  - BusyBox wget thru 1.3.7 accepted raw CR (0x0D)/LF (0x0A) and other C0 control bytes in the HTTP request-
    target (path/query), allowing the request line to be split and attacker-controlled headers to be injected.
    To preserve the HTTP/1.1 request-line shape METHOD SP request-target SP HTTP/1.1, a raw space (0x20) in
    the request-target must also be rejected (clients should use %20). (CVE-2025-60876)

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