Nas versões afetadas do WordPress, arquivos com um nome especialmente criado, quando enviados para a seção Mídia, podem levar à execução de scripts ao acessar o arquivo. Isso requer um usuário autenticado com privilégios para enviar arquivos. A vulnerabilidade está relacionada a medidas de proteção insuficientes nos componentes `formatting.php` e `SanitizeFileName.php`, o que pode permitir que um invasor remoto comprometa a integridade dos dados.

Name of the Vulnerable Software and Affected Versions: Microsoft Visual Basic 6.0 Microsoft Visual FoxPro versions 8.0 SP1 through 9.0 SP2 Description: The issue is related to multiple integer overflows in the Hierarchical FlexGrid ActiveX control, which allows remote attackers to execute arbitrary code. This is achieved by crafting specific properties, such as `Rows` and `Cols`, to the `ExpandAll` and `CollapseAll` methods. The exploitation is linked to the access of incorrectly initialized objects and the corruption of the system state. Recommendations: For Microsoft Visual Basic 6.0, update to a version that includes the fix for the Hierarchical FlexGrid Control Memory Corruption issue. For Microsoft Visual FoxPro versions 8.0 SP1 through 9.0 SP2, update to a version that includes the fix for the Hierarchical FlexGrid Control Memory Corruption issue. As a temporary workaround, consider restricting access to the Hierarchical FlexGrid ActiveX control until a patch is available.
