Detailsinfo

A vulnerability was found in realmd (the affected version unknown). It has been classified as critical. This affects an unknown part of the file sssd.conf of the component LDAP Response Handler. The manipulation with an unknown input leads to a injection vulnerability (Config). CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:

realmd allows remote attackers to inject arbitrary configurations in to sssd.conf and smb.conf via a newline character in an LDAP response.
