https://notcve.org/view.php?id=CVE-2022-4254
sssd: libsss_certmap fails to sanitise certificate data used in LDAP filters A vulnerability was found in SSSD, in the libsss_certmap functionality. PKINIT enables a client to authenticate to the KDC using an X.509 certificate and the corresponding private key, rather than a passphrase or keytab. FreeIPA uses mapping rules to map a certificate presented during a PKINIT authentication request to the corresponding principal. The mapping filter is vulnerable to LDAP filter injection. The search result can be influenced by values in the certificate, which may be attacker controlled. • https://access.redhat.com/security/cve/CVE-2022-4254 https://bugzilla.redhat.com/show_bug.cgi?id=2149894 https://github.com/SSSD/sssd/commit/a2b9a84460429181f2a4fa7e2bb5ab49fd561274 https://github.com/SSSD/sssd/issues/5135 https://lists.debian.org/debian-lts-announce/2023/05/msg00028.html • CWE-90: Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection') •
CVSS: 5.2EPSS: 0%CPEs: 6EXPL: 0CVE-2019-3811 – sssd: fallback_homedir returns '/' for empty home directories in passwd file
https://notcve.org/view.php?id=CVE-2019-3811
A vulnerability was found in sssd. If a user was configured with no home directory set, sssd would return '/' (the root directory) instead of '' (the empty string / no home directory). This could impact services that restrict the user's filesystem access to within their home directory through chroot() etc. All versions before 2.1 are vulnerable.

sssd versions from 1.13.0 to before 2.0.0 did not properly restrict access to the infopipe according to the "allowed_uids" configuration parameter. If sensitive information were stored in the user directory, this could be inadvertently disclosed to local attackers. sssd, desde la versión 1.13.0 hasta antes de la 2.0.0, no restringió correctamente el acceso a la infopipe según el parámetro de configuración "allowed_uids". Si se almacena información sensible en el directorio de usuario, esto podría divulgarse de forma inadvertida a los atacantes locales. • http://www.securityfocus.com/bid/106264 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16883 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2018-10852
The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD has too wide permissions, which means that anyone who can send a message using the same raw protocol that sudo and SSSD use can read the sudo rules available for any user. This affects versions of SSSD before 1.16.3. El pipe de Unix que utiliza sudo para contactar SSSD y leer las reglas sudo disponibles desde SSSD tiene permisos demasiado laxos, lo que significa que cualquiera que pueda enviar un mensaje utilizando el mismo protocolo raw que utilizan sudo y SSSD puede leer reglas sudo disponibles para cualquier usuario.

https://notcve.org/view.php?id=CVE-2017-12173
It was found that sssd's sysdb_search_user_by_upn_res() function before 1.16.0 did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated attacker could use this flaw to retrieve it. Se ha encontrado que la función sysdb_search_user_by_upn_res() de sssd en versiones anteriores a la 1.16.0 no saneaba las peticiones al consultar su caché local y era vulnerable a inyecciones.
