Kutumia SSRF katika mazingira ya AWS EC2

Endpoint ya metadata inaweza kufikiwa kutoka ndani ya mashine yoyote ya EC2 na inatoa habari muhimu kuhusu hiyo. Inapatikana kwa url: http://169.254.169.254 (habari kuhusu metadata hapa).

Kuna toleo 2 la endpoint ya metadata. La kwanza inaruhusu kufikia endpoint kupitia maombi ya GET (hivyo SSRF yoyote inaweza kuidhuru). Kwa toleo 2, IMDSv2, unahitaji kuomba tokeni kwa kutuma ombi la PUT na HTTP header kisha kutumia tokeni hiyo kufikia metadata na HTTP header nyingine (hivyo ni ngumu zaidi kuidhuru na SSRF).

{% hint style="danger" %} Tambua kwamba ikiwa kifaa cha EC2 kinafuata IMDSv2, kulingana na nyaraka, jibu la ombi la PUT litakuwa na kikomo cha hatua 1, kufanya iwe haiwezekani kufikia metadata ya EC2 kutoka kwenye chombo ndani ya kifaa cha EC2.

Zaidi ya hayo, IMDSv2 pia itazuia maombi ya kupata tokeni ambayo yanajumuisha kichwa cha X-Forwarded-For. Hii ni ili kuzuia wakala wa kurudisha misimamo iliyopangwa vibaya kutoka kuweza kufikia hiyo. {% endhint %}

Unaweza kupata habari kuhusu endpoints ya metadata katika nyaraka. Katika hati ya kufuatia, habari muhimu inapatikana kutoka kwake:

Kama mfano wa vyeti vya IAM vilivyofichuliwa kwa umma unaweza kutembelea: http://4d0cf09b9b2d761a7d87be99d17507bce8b86f3b.flaws.cloud/proxy/169.254.169.254/latest/meta-data/iam/security-credentials/flaws

Unaweza pia kuangalia vyeti vya usalama vya EC2 vya umma katika: http://4d0cf09b9b2d761a7d87be99d17507bce8b86f3b.flaws.cloud/proxy/169.254.169.254/latest/meta-data/identity-credentials/ec2/security-credentials/ec2-instance

Kisha unaweza kuchukua vyeti hivyo na kuvitumia na AWS CLI. Hii itakuruhusu kufanya chochote ambacho jukumu hilo lina ruhusa kufanya.

Kutumia vyeti vipya, utahitaji kuunda wasifu mpya wa AWS kama huu:

Tambua aws_session_token, hii ni muhimu kwa wasifu kufanya kazi.

PACU inaweza kutumika na siri zilizopatikana kujua haki zako na jaribu kuinua haki

SSRF katika AWS ECS (Huduma ya Kontena) siri

ECS, ni kikundi la mantiki la visa vya EC2 ambavyo unaweza kukimbia programu bila kuhitaji kupanua miundombinu yako ya usimamizi wa kikundi kwa sababu ECS inasimamia hilo kwa niaba yako. Ikiwa unafanikiwa kudhoofisha huduma inayotumika katika ECS, vifaa vya mwisho vya metadata hubadilika.

Ikiwa unafikia http://169.254.170.2/v2/credentials/<GUID> utapata siri za mashine ya ECS. Lakini kwanza unahitaji kupata <GUID>. Ili kupata <GUID> unahitaji kusoma mazingira ya kipekee AWS_CONTAINER_CREDENTIALS_RELATIVE_URI ndani ya mashine.
Unaweza kuisoma kwa kutumia Path Traversal kwa file:///proc/self/environ
Anwani ya http iliyotajwa inapaswa kukupa AccessKey, SecretKey na token.

curl "http://169.254.170.2$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI" 2>/dev/null || wget "http://169.254.170.2$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI" -O -

{% hint style="info" %} Tafadhali elewa kwamba katika baadhi ya kesi utaweza kupata ufikivu wa taarifa ya EC2 metadata instance kutoka kwenye kontena (angalia vikwazo vya IMDSv2 TTL vilivyotajwa hapo awali). Katika hali hizi kutoka kwenye kontena unaweza kupata ufikivu wa jukumu la IAM la kontena na jukumu la IAM la EC2. {% endhint %}

SSRF kwa AWS Lambda

Katika kesi hii vyeti vimehifadhiwa kwenye mazingira ya env. Kwa hivyo, ili kuzipata unahitaji kupata kitu kama file:///proc/self/environ.

Jina la mazingira ya env yanayovutia ni:

AWS_SESSION_TOKEN
AWS_SECRET_ACCESS_KEY
AWS_ACCES_KEY_ID

Zaidi ya hayo, mbali na vyeti vya IAM, Lambda functions pia zina data ya tukio ambayo hupitishwa kwa kazi wakati inapoanzishwa. Data hii inapatikana kwa kazi kupitia interface ya runtime na inaweza kuwa na taarifa nyeti (kama vile ndani ya stageVariables). Tofauti na vyeti vya IAM, data hii inapatikana kupitia SSRF ya kawaida kwa http://localhost:9001/2018-06-01/runtime/invocation/next.

{% hint style="warning" %} Tafadhali elewa kwamba vyeti vya lambda vimo ndani ya mazingira ya env. Kwa hivyo, ikiwa mnyororo wa kufuatilia wa nambari ya lambda unachapisha mazingira ya env, ni rahisi kuzipata kwa kusababisha kosa katika programu. {% endhint %}

URL ya SSRF kwa AWS Elastic Beanstalk

Tunapata accountId na region kutoka kwenye API.

http://169.254.169.254/latest/dynamic/instance-identity/document
http://169.254.169.254/latest/meta-data/iam/security-credentials/aws-elasticbeanorastalk-ec2-role

Tunakisha kupata AccessKeyId, SecretAccessKey, na Token kutoka kwenye API.

http://169.254.169.254/latest/meta-data/iam/security-credentials/aws-elasticbeanorastalk-ec2-role

Kisha tunatumia siri za aws s3 ls s3://elasticbeanstalk-us-east-2-[ACCOUNT_ID]/.

echo $IDENTITY_ENDPOINT

# You should also be able to find the folder:
