Vulnerability Data

Apache OpenOffice documents can contain links that call internal macros with arbitrary arguments. Several URI Schemes are defined for this purpose. Links can be activated by clicks, or by automatic document events. The execution of such links must be subject…

to user approval. In the affected versions of OpenOffice, approval for certain links is not requested; when activated, such links could therefore result in arbitrary script execution. This is a corner case of CVE-2022-47502.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

PM-14 Testing, Training, and Monitoring
addresses: CWE-20

Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.

SA-11 Developer Testing and Evaluation
addresses: CWE-20

Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.

SI-10 Information Input Validation
addresses: CWE-20

Directly implements checks on information inputs to reject invalid data before processing.

SI-8 Spam Protection
addresses: CWE-20

Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-20, a class-level weakness, and none of its children carries one either.
