What Changed
Check Point revised its advisory after observing exploitation attempts against Spark customers beginning September 12. The vendor directs customers to install the applicable fix and review anomalous certificate-based Mobile Access logins and subsequent internal scanning.
What To Validate Now
- Inventory. Locate Check Point Security Gateways and Spark appliances in the affected R81 and R82 streams deployments, versions, enabled features, exposure paths, owners, and dependent services.
- Establish applicability. Compare each deployment with the authority's affected-version statement: Security Gateway and Spark Firewall releases R81, R81.10, R81.10.X, R81.20, R82, R82.00.X, and R82.10 as listed by Check Point Do not infer applicability from product family or severity alone.
- Remediate. Apply Install the applicable fix published in sk1000117; replace unsupported R81 and R81.10 releases through the supported vendor or project channel, following the current advisory and change-control requirements.
- Validate. Confirm the resulting version or managed-service state, exercise representative functionality and recovery paths, monitor for regressions, and document exceptions.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Use the exact supported release stream and repository. Test dependencies, clusters, integrations, and rollback before broad deployment; a CVSS rating or reachable feature is not evidence of exploitation.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
