CVE-2022-45141
Last modified
CVE-2022-45141 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Since the Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability was disclosed by Microsoft on Nov 8 2022 and per RFC8429 it is assumed that rc4-hmac is weak, Vulnerable Samba Active Directory DCs will issue rc4-hmac encrypted tickets despite the target server supporting better encryption (eg aes256-cts-hmac-sha1-96).. EPSS estimates a 0.45% chance of exploitation in the next 30 days.
