Apache OpenOffice documents can contain links
Why It Matters
Analysis dossierWhy It Matters
Apache OpenOffice documents can contain links. A missing Authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In the affected versions of Apache OpenOffice, documents that used "floating frames" linked to external files would load the contents of those frames without prompting the user for permission to do so. This issue affects Apache OpenOffice: through 4.1.15. Users are recommended to upgrade to version 4.1.16, which fixes the issue. The LibreOffice suite reported this issue as CVE-2023-2255

Suggested hunting (rule-based inference)
SecOps Signal recommendation (rule-based inference). These steps are hunting hypotheses from the vulnerability class; they do not state or imply that exploitation occurred here or anywhere.
Matched authorization-bypass (CWE-862); network-unauthenticated (CVSS AV:N, CVSS PR:N, CVSS UI:N)
Exposure
- Locate affected authorization controls and verify deployed versions.Telemetry: Application inventory · The source must identify the affected control. · Rule authorization-bypass
- Identify devices reporting this CVE and note which expose the affected service to untrusted networks.Telemetry: DeviceTvmSoftwareVulnerabilities · A network-reachable, no-privilege vector makes internet-facing instances the first exposure question. · Rule network-unauthenticated
Exploitation evidence
- Review privileged operations performed by unexpected users on affected deployments.Telemetry: Application audit logs · Authorization anomalies can support a targeted hunt. · Rule authorization-bypass

Exploitation evidence
- Review inbound connections to the affected service from unexpected sources since the advisory date.Telemetry: DeviceNetworkEvents · Hunting hypothesis from the CVSS vector; it does not show that exploitation occurred. · Rule network-unauthenticated
Response
- Confirm the vendor mitigation and recheck access decisions.Telemetry: Application audit logs · Access testing verifies the local fix. · Rule authorization-bypass
