Elevation of Privilege Vulnerability in Samba Active Directory
CVE-2022-45141
9.8CRITICAL
What is CVE-2022-45141?
The Samba Active Directory Domain Controllers are susceptible to an elevation of privilege vulnerability due to the use of the rc4-hmac encryption algorithm. Despite the presence of better encryption options such as aes256-cts-hmac-sha1-96, vulnerable Samba DCs can issue rc4-hmac encrypted tickets. This flaw arises from the deprecation of rc4-hmac as weak encryption as established by RFC8429, presenting a risk for unauthorized access and exploitation. Organizations must assess their systems to mitigate associated risks.
