HighCVSS 8.5 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 4.2% (FIRST EPSS); higher than 91.2% of all records.
  • Fixed version: samba (Debian:12) 2:4.1.17+dfsg-1.

Low priority for now. Upgrade to samba (Debian:12) 2:4.1.17+dfsg-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Samba 4.0.x before 4.0.24, 4.1.x before 4.1.16, and 4.2.x before 4.2rc4, when an Active Directory Domain Controller (AD DC) is configured, allows remote authenticated users to set the LDB userAccountControl UF_SERVER_TRUST_ACCOUNT bit, and consequently gain privileges, by leveraging delegation of authority for user-account or computer-account creation.
