8DescriptionNVD
A security vulnerability has been detected in Collabora KodExplorer up to 4.52. Affected by this issue is some unknown functionality of the file /app/controller/share.class.php of the component fileUpload Endpoint. The manipulation of the argument fileUpload leads to improper authorization. Remote exploitation of the attack is possible. The attack's complexity is rated as high. The exploitation is known to be difficult. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Improper authorization in Collabora KodExplorer up to version 4.52 allows remote unauthenticated attackers to bypass authentication via manipulation of the fileUpload parameter in the /app/controller/share.class.php endpoint, potentially enabling unauthorized file access or modification with low confidentiality, integrity, and availability impact. Publicly available exploit code exists; however, the attack requires high complexity and is described as difficult to execute in practice, limiting real-world exploitation despite public disclosure and vendor non-responsiveness.
