This is a follow up to GHSA-887w-pv2r-x8pm/CVE-2021-41276, the initial fix was incomplete. Tuleap does not sanitize properly the search filter built from the ldap_id attribute of a user during the daily synchronization. A malicious user could force accounts to be suspended or take over another account by forcing the update of the ldap_uid attribute. Note that the malicious user either need to have site administrator capability on the Tuleap instance or be an LDAP operator with the capability to create/modify account. The Tuleap instance needs to have the LDAP plugin activated and enabled for this issue to be exploitable. The following versions contain the fix: Tuleap Community Edition 13.2.99.83, Tuleap Enterprise Edition 13.1-6, and Tuleap Enterprise Edition 13.2-4."

Esto es un seguimiento de GHSA-887w-pv2r-x8pm/CVE-2021-41276, la correcci\u00f3n inicial era incompleta. Tuleap no sanea adecuadamente el filtro de b\u00fasqueda construido a partir del atributo ldap_id de un usuario durante la sincronizaci\u00f3n diaria. Un usuario malicioso podr\u00eda forzar la suspensi\u00f3n de cuentas o tomar el control de otra cuenta al forzar la actualizaci\u00f3n del atributo ldap_uid. Ten en cuenta que el usuario malicioso debe tener capacidad de administrador del sitio en la instancia de Tuleap o ser un operador LDAP con capacidad para crear/modificar cuentas. La instancia de Tuleap necesita tener el plugin LDAP activado y habilitado para que este problema sea explotable. Las siguientes versiones contienen la correcci\u00f3n: Tuleap Community Edition versi\u00f3n 13.2.99.83, Tuleap Enterprise Edition versi\u00f3n 13.1-6, y Tuleap Enterprise Edition versi\u00f3n 13.2-4"
