OWASP Top 10 Coverage Matrix for Dispatcher

OWASP Top 10 2021 - Dispatcher Controls

A01:2021 - Broken Access Control

Dispatcher Controls:

• Filter rules (allow/deny)
• Virtual host restrictions
• Method-based access controls

Audit Checks:

• Deny-by-default filter posture
• Admin paths blocked (/crx/*, /system/*)
• Sensitive servlets protected (/bin/querybuilder*)
• Method restrictions enforced (POST/PUT/DELETE)
• No glob wildcard allows

MCP Validation:

trace_request({"url":"/crx/de/index.jsp","method":"GET"})          # Should deny
trace_request({"url":"/content/site/en.html","method":"POST"})     # Should deny (read-only)
trace_request({"url":"/bin/querybuilder.json","method":"GET"})     # Should deny

Severity if Failed: Critical

A02:2021 - Cryptographic Failures

Dispatcher Controls:

• SSL/TLS configuration
• HSTS headers
• Secure cookie attributes (forwarded from backend)

Audit Checks:

• TLS 1.2+ only (SSLv2/3, TLS 1.0/1.1 disabled)
• Strong cipher suites only
• Valid SSL certificates (not expired, not self-signed)
• HSTS header present on HTTPS
• No sensitive data cached unencrypted

MCP Validation:

# Check HTTPS config statically (vhost content)
validate({"config":"<vhost.conf content>","type":"httpd"})
lint({"mode":"directory","target":"/path/to/dispatcher/src","strict_mode":true})

# MCP does not directly return live response headers.
# Verify HSTS via config presence and, when available, external HTTP probe:
# curl -sI https://site.com/content/site/en.html | grep Strict-Transport-Security

Severity if Failed: High to Critical

A03:2021 - Injection

Dispatcher Controls:

• Query parameter filtering
• Selector/extension validation
• Path traversal prevention

Audit Checks:

• Query parameters sanitized before caching
• No SQL/NoSQL injection vectors via dispatcher
• Path traversal blocked (../* patterns)
• Selector/extension bypass prevented

MCP Validation:

trace_request({"url":"/content/site/../../../etc/passwd","method":"GET"})        # Should deny/400
trace_request({"url":"/content/site/en.html?query=<script>","method":"GET"})     # Should sanitize
trace_request({"url":"/content/site/en.json;.css","method":"GET"})                # Should handle safely

Severity if Failed: High

A04:2021 - Insecure Design

Dispatcher Controls:

• Configuration architecture (immutable files, includes)
• Least-privilege defaults

Audit Checks:

• Deny-by-default architecture
• Immutable files unmodified (ams)
• Least-privilege filter rules
• Security-first cache policy
• Include structure follows best practices

MCP Validation:

lint({"mode":"directory","target":"/path/to/dispatcher/src","strict_mode":true})
sdk({"action":"check-files","config_path":"/path/to/dispatcher/src"})
validate({"config":"<dispatcher.any content>","type":"ams"})

Severity if Failed: Medium

A05:2021 - Security Misconfiguration

Dispatcher Controls:

• Default deny filters
• Security headers
• Version disclosure prevention
• Error page configuration

Audit Checks:

• No default/example configs left enabled
• Security headers configured
• Server version hidden
• Directory listing disabled
• Error pages sanitized (no stack traces)

MCP Validation:

lint({"mode":"directory","target":"/path/to/dispatcher/src","strict_mode":true})
validate({"config":"<httpd/vhost header config content>","type":"httpd"})
inspect_cache({"url":"/content/site/en.html","show_metadata":true})
# For live header proof, use external HTTP probe in environment:
# curl -sI https://site.com/content/site/en.html

Severity if Failed: Medium to High

A06:2021 - Vulnerable and Outdated Components

Dispatcher Controls:

• Dispatcher version management
• Apache version management

Audit Checks:

• Dispatcher version is latest stable
• Apache version is patched
• No known CVEs in deployed versions
• Regular update schedule documented

MCP Validation:

# Check dispatcher version
# Verify against: https://experienceleague.adobe.com/en/docs/experience-manager-dispatcher/using/getting-started/release-notes

Severity if Failed: High (if CVEs present)

A07:2021 - Identification and Authentication Failures

Dispatcher Controls:

• Pass-through to AEM (dispatcher doesn't handle auth)
• Session cookie security (forwarded from AEM)
• Protected admin paths

Audit Checks:

• Admin paths require backend auth
• No auth bypass via dispatcher filters
• Secure cookie attributes forwarded
• No credentials in logs

MCP Validation:

trace_request({"url":"/system/console","method":"GET"})  # Should deny before reaching AEM
tail_logs({"lines":1000})
# Review returned entries for sensitive tokens/password patterns.

Severity if Failed: Critical (if bypass possible)

A08:2021 - Software and Data Integrity Failures

Dispatcher Controls:

• Immutable file integrity (ams)
• Configuration baseline monitoring
• Cache integrity

Audit Checks:

• Immutable files match baseline (ams)
• Config changes tracked
• Cache invalidation prevents stale data
• No unauthorized config modifications

MCP Validation:

sdk({"action":"diff-baseline","config_path":"/path/to/dispatcher/src"})
sdk({"action":"check-files","config_path":"/path/to/dispatcher/src"})

Severity if Failed: Medium

A09:2021 - Security Logging and Monitoring Failures

Dispatcher Controls:

• Access logging
• Error logging
• Security event logging (denies, errors)

Audit Checks:

• Filter denies logged
• 4xx/5xx errors logged
• Access logs enabled
• Log rotation configured
• No sensitive data in logs

MCP Validation:

tail_logs({"lines":100})
monitor_metrics({"window_minutes":60,"breakdown_by":"status_code"})

Severity if Failed: Low to Medium

A10:2021 - Server-Side Request Forgery (SSRF)

Dispatcher Controls:

• Filter rules blocking metadata and service endpoints
• Backend origin validation

Audit Checks:

• Metadata and service endpoints blocked
• No open proxy behavior
• Loopback requests denied
• Link-local or metadata IP ranges blocked (if applicable)

MCP Validation:

trace_request({"url":"/content/site/proxy?url=http://<loopback-target>","method":"GET"})           # Should deny
trace_request({"url":"/content/site/proxy?url=http://<metadata-service-address>","method":"GET"})  # Should deny

Severity if Failed: High

Finding Template

## OWASP A01:2021 - Broken Access Control

**Severity:** Critical
**Status:** Failed

**Finding:**
Admin console accessible without authentication via `/crx/de/index.jsp`.

**Evidence:**
```text
trace_request({"url":"/crx/de/index.jsp","method":"GET"})
status: passed/allowed

Impact:

• Direct system access
• Full content tree access
• Potential system compromise

Recommendation: Add deny rule for admin paths with highest priority. Place the deny after any allow that matches the path (last-applied filter wins).

/filter {
    /0000 { /glob "*" /type "deny" }
    /0001 { /glob "/crx/*" /type "deny" }
    /0002 { /glob "/system/*" /type "deny" }
    # ... other allows ...
}

Verification:

trace_request({"url":"/crx/de/index.jsp","method":"GET"})
# Expected: filter stage status = denied

## Automated OWASP Check Pattern

```text
Use your automation runner to execute MCP calls and score checks:

1) access = trace_request({"url":"/crx/de/index.jsp","method":"GET"})
2) traversal = trace_request({"url":"/content/../../../etc/passwd","method":"GET"})
3) static_check = lint({"mode":"directory","target":"/path/to/dispatcher/src","strict_mode":true})
4) integrity = sdk({"action":"check-files","config_path":"/path/to/dispatcher/src"})
5) drift = sdk({"action":"diff-baseline","config_path":"/path/to/dispatcher/src"})

Then score pass/fail using returned stage statuses and issue severities.
For live response-header checks (HSTS/CSP/etc), add external HTTP probes in the same pipeline.
