Goal

Detect OGNL injection attempts on routes with errors related to OGNL parsing. Such security activity generally indicates that an attacker is trying to exploit a potential OGNL vulnerability.

Strategy

Monitor OGNL injection attempts ((@appsec.rule_id:dog-000-002 or @appsec.security_activity:attack_attempt.java_code_injection)) on services generating errors related to OGNL expression parsing (@_dd.appsec.enrichment.error_types:ognl.ExpressionSyntaxException).

Generate an Application Security Signal with High severity.

Triage and response

Consider blocking the attacking IP(s) temporarily to prevent them from reaching deeper parts of your production systems.
Investigate the errors generated by this attack to identify if any vulnerabilities need to be fixed.
