We had to automate this challenge, the goal was to answer all the math questions. Hint : All answers are integers !
Here is the script :
from selenium import webdriver
from bs4 import BeautifulSoup as soup
import time
url = "http://workshop.web1.sunshinectf.org/"
mydriver = webdriver.Firefox()
mydriver.get(url)
mydriver.find_element_by_xpath("(//*[text()='Start'])[1]").click()
time.sleep(0.8)
while True:
time.sleep(1)
pageSoup = soup(mydriver.page_source, "html.parser")
question = pageSoup.find("h1", {"id": "question"}).text
q1 = question.split(' ')[-3]
q2 = question.split(' ')[-1]
find = mydriver.find_element_by_xpath("//*[@{}='{}']".format(q1, q2))
split = find.text.split()
answer = str(int(eval("{}{}{}".format(split[0], split[1], split[2]))))
try:
find.find_element_by_name("input").send_keys(answer)
except:
for x in find.find_elements_by_xpath(".//input"):
if x.get_attribute("text") == answer:
x.click()
break
find.find_element_by_tag_name("button").click()
time.sleep(10)
mydriver.quit()
After running the script you got the flag :
