CVE-2024-6472

Macro execution via forgeable certificate identity prompt

Published Aug 5, 2024 · Updated Aug 5, 2024

Certificate-validation failure in LibreOffice 24.2 before 24.2.5 allows attackers to execute signed macros through crafted documents. The SfxObjectShell macro-security flow allowed hasTrustedScriptingSignature to add a signer after validation failed while emphasizing a forgeable Common Name. Exploitation requires a user to open the document and approve the invalid signer, after which its macros execute with that user's privileges.
