Config::IniFiles versions before 3.001000 for Perl allow OS command injection and file overwrite via a 2-arg open() of the -file argument in _make_filehandle. Config::IniFiles::_make_filehandle opens a filename argument with Perl's 2-arg open(), so a filename that begins or ends with a pipe ("| cmd", "cmd |") or begins with a redirect ("> path", ">> path") is run as a command or redirect rather than opened as a file. The helper is the open path behind the documented -file argument: new(-file => $thing) reaches it through ReadConfig. An in-memory scalar reference (-file => \$text) does not open a path and is unaffected. Any caller that forwards untrusted input to the -file argument can run an arbitrary command or truncate a file under the process UID.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Config::IniFiles versions before 3.001000 for Perl allow OS command injection and file overwrite via a
    2-arg open() of the -file argument in _make_filehandle. Config::IniFiles::_make_filehandle opens a
    filename argument with Perl's 2-arg open(), so a filename that begins or ends with a pipe ("| cmd", "cmd
    |") or begins with a redirect ("> path", ">> path") is run as a command or redirect rather than opened as
    a file. The helper is the open path behind the documented -file argument: new(-file => $thing) reaches it
    through ReadConfig. An in-memory scalar reference (-file => \$text) does not open a path and is
    unaffected. Any caller that forwards untrusted input to the -file argument can run an arbitrary command or
    truncate a file under the process UID. (CVE-2026-11527)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Config::IniFiles versions before 3.001000 for Perl allow OS command injection and file overwrite via a     2-arg open() of the -file argument in _make_filehandle. Config::IniFiles::_make_filehandle opens a     filename argument with Perl's 2-arg open(), so a filename that begins or ends with a pipe (| cmd, cmd     |) or begins with a redirect (> path, >> path) is run as a command or redirect rather than opened as     a file. The helper is the open path behind the documented -file argument: new(-file => $thing) reaches it     through ReadConfig. An in-memory scalar reference (-file => \$text) does not open a path and is     unaffected. Any caller that forwards untrusted input to the -file argument can run an arbitrary command or     truncate a file under the process UID. (CVE-2026-11527)

Note that Nessus relies on the presence of the package as reported by the vendor.
