BugBounty Tips

Collection of #bugbountytips from twitter and my bash-jutsu.

Recon

Google the company copyright footer to get more domains.
Use whoxy.com to perform reverse whois lookups with the email used to register the main domain/
Search for slide,docs,demos and video tutorials by your target. Manny innocent examples could leak juicy endpoints.
Use OpenSSL to get certificates. They can contain valuable info and common names form finding more subdomains.
Try to recreate data from deleted accounts by siging up with the old email address.
Check text version of HTML e-mail for template injections
When testing Rails Application add .json to url endpoints.
cat file | grep -Eo "(http|https)://[a-zA-Z0-9./?=_-]*"*
curl http://host.xx/file.js | grep -Eo "(http|https)://[a-zA-Z0-9./?=_-]*"* 
grep -EHirn "accesskey|admin|aes|api_key|apikey|checkClientTrusted|crypt|http:|https:|password|pinning|secret|SHA256|SharedPreferences|superuser|token|X509TrustManager|insert into|DB_USER|DB_PASSWORD" folder/

Subdomain Enumeration

sublist3r -d $1 -o $1.txt
mkdir thirdlevel
echo "Gathering full third-level domain with sublister"
for domain in $(cat $1.txt); do sublist3r -d $domain -o thirdlevel/$domain.txt; cat thirdlevel/$domain.txt | sort -u >> final.txt; done 
echo "Probing for alive third-levels..."
cat final.txt | httprobe > probed.txt

subdomain level extraction

Regex pattern	Domain level match
grep -P '^(?:[a-z0-9]+.){1}[^.]*$'	2nd level domains only
grep -P '^(?:[a-z0-9]+.){2}[^.]*$'	3rd level domains only
grep -P '^(?:[a-z0-9]+.){2,}[^.]*$'	3rd level domains or higher
grep -P '^(?:[a-z0-9]+.){2,3}[^.]*$'	3rd to 4th level domains only
grep -P '^(?:[a-z0-9]+.){3,}[^.]*$'	4th level domains or higher

Check live

cat GREPABLENMAP.gnmap | grep 443/open | cut -d "(" -f 1 | cut -d : -f 2| tr -d " " | sed -E 's#https?://##I' | sed -E 's#/.*##' | sed -E 's#^\*\.?##' | sed -E 's#,#\n#g' | tr '[:upper:]' '[:lower:]' | uniq | sed -e 's/^/https:\/\//' | httpx -silent -timeout 2 -threads 100 -status-code -mc 200,302 |anew

Check live webapps from sublis3r

cat subdomains.txt | sed -E 's#https?://##I' | sed -E 's#/.*##' | sed -E 's#^\*\.?##' | sed -E 's#,#\n#g' | tr '[:upper:]' '[:lower:]' | uniq | sed -e 's/^/https:\/\//' | httpx -silent -timeout 2 -threads 100 -status-code -mc 200,302 |anew

Filter ffuf output

cat * | jq | grep "url\"" | grep -v "replayproxyurl" |grep -v "proxyurl"  | grep -v "FUZZ" | cut -d \" -f4

Extract juicy data from js

go install -v github.com/punishell/gofinder@v0.1.1
echo example.com | assetfinder | httprobe| subjs | gofinder

Tools

Use exiftool to extract metadata from documents, it might reveal vulnerable htmltopdf generators
Use cloud_enum to find open google buckets or azure accounts 
Use Grep to extract endpoints with grep: grep -o -E '(https?://)?/?[{}a-z0-9A-Z_\.-]{2,}/[{}/a-z0-9A-Z_\.-]+'
Use WayBackmachine combined with paraminer or parameth
Passive parameter mining web.archive.org /cdx/search/cdx?url=*.target.com/*&output=text&fl=original&collapse=urlkey
Burp Collaborator alternative https://app.interactsh.com/#/

Payloads

Inject payloads in parameter names, ?<script>alerty</script>=true
Use youtube(olx, etc...) videos with xss in names.
Use round brackets to inject payload into valid e-mail address.
X-Forwarded-For: ${payload}
Use longstring parameters for stacktrace.
WAFBYPASS ?page=";confirm`1`//   Rightwards -> 302; ?pag%65=";confirm`1`//   Rightwards -> 200 + XSS!
Redirect bypass %26next=http://example.com 
When testing nodejs site add %ff at the end of url https://target.com/%ff, most of times cause error and return stacktrace with full path
Add [] to name of parrameter: pwd= ->pwd[]=
when interacting with db try to put % in parameter  ?item=%

Authentication & Autorization

UUID Idor Trick, Register user with the same name, it maybe return uuid.
Try to bruteforce login endpoint. /login/${oauth_provider}, login/facebook, login/oauth/twitter login/oauth/v2/yahoo
403 Forbidden bypass, https://host.com/path =403, https://host.com/%2e/path = 200, 
Bypass paywalls by using Google Bot user agent.
User securitytrails.com to find the originating server IP
Do match and replace form false to true.
Set your birthday for today ot tomorrow to get discounts.
Skip steps: /step/shipping ->  ~~/step/payment~~ -> /step/confirm
Check does blackfriday coupon codes expires.
Use blind xss as password.
Login to site using Facebook and try tochange userid during POST requests
/api/v1/users/profile?id=MYID&id=ANOTHERUSERID -> HTTP 200

Data leakage through .json

Here’s a tip to achieve sensitive data leak using .json extension.

Request:
GET /ResetPassword HTTP/1.1
{"email":"victim@example.com"}

Response:
HTTP/1.1 200 OK
Now let’s try this instead:

Request:
GET /ResetPassword.json HTTP/1.1
{"email":"victim@example.com"}

Response:
HTTP/1.1 200 OK
{"success":"true","token":"596a96-cc7bf-9108c-d896f-33c44a-edc8a"}
