Description
A flaw was found in SSSD. When configured with the Entra ID identity provider, input lookup names containing single quotes are not properly escaped before being included in Microsoft Graph Open Data Protocol (OData) queries. A low-privileged local user can exploit this flaw by submitting a crafted search request, altering query filters to broaden user or group searches. This can lead to information disclosure by retrieving unintended directory objects, as well as a Denial of Service (DoS) through excessive processing and cache population.
