The krb5_save_ccname_done function in providers/krb5/krb5_auth.c in System Security Services Daemon (SSSD) 1.5.x before 1.5.7, when automatic ticket renewal and offline authentication are configured, uses a pathname string as a password, which allows local users to bypass Kerberos authentication by listing the /tmp directory to obtain the pathname.

CVE-2011-1758 sssd: automatic TGT renewal overwrites cached password with value of predicatable filename
bugzilla·2011-04-29·CVSS 3.7
CVE-2011-1758 [LOW] CVE-2011-1758 sssd: automatic TGT renewal overwrites cached password with value of predicatable filename
CVE-2011-1758 sssd: automatic TGT renewal overwrites cached password with value of predicatable filename
A flaw was introduced in SSSD 1.5.0 that, under certain conditions, would have sssd overwrite a cached password with the filename of the kerberos credential store (defined by krb5_ccache_template in sssd.conf). This could allow an attacker to gain access to an account without knowing the password if they knew the cached-credential string.
This flaw does not affect earlier versions of SSSD that did not have support for automatic ticket renewal services.
