A variation to the theme:

UPDATE table SET field = substr(FIELD,1,3)|| '08' || substr(FIELD,6)
WHERE substr(FIELD,4,2) = '18';

Oracle has the Replace function but that will replace all occurrences of one value to another. So if you can have multiple "15" in the field, replace can't be used for your situation. For your example of replacing 15 with 08, try something like this:

update table 
set field = substr(field,1,3) || '08' || substr(field,6,4))
where substr(field,4,2)='15';

If the rows will only have a 15 in position 4 and 5, you could use:

update table
set field = replace(field,'15','08');
