Metasploit Framework

Msf::Exploit::Remote::Postgres#postgres_upload_binary_data

Writes data to disk on the target server.

This is accomplished in 5 steps:
1. Create a new object with "select lo_create(-1)"
2. Delete any resulting rows in pg_largeobject table.
   On 8.x and older, postgres inserts rows as a result of the call to
   lo_create. Deleting them here approximates the state on 9.x where no
   such insert happens.
3. Break the data into LOBLOCKSIZE-byte chunks.
4. Insert each of the chunks as a row in pg_largeobject
5. Select lo_export to write the file to disk
