CVE-2018-2439 — Sap Internet Graphics Server security vulnerability

Medium CVSS 5.9

The SAP Internet Graphics Server (IGS), 7.20, 7.20EXT, 7.45, 7.49, 7.53, has insufficient request validation (for example, where the request is validated for authenticity and validity) and under certain conditions, will process invalid requests. Several areas of the SAP Internet Graphics Server (IGS) did not require sufficient input validation. Namely, the SAP Internet Graphics Server (IGS) HTTP and RFC listener, SAP Internet Graphics Server (IGS) portwatcher when registering a portwatcher to the multiplexer and the SAP Internet Graphics Server (IGS) multiplexer had insufficient input validation and thus allowing a malformed data packet to cause a crash.

Matched remediation archetype

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
