CVE-2004-0815: The unix_clean_name function in Samba 2.2.x through 2.2.11, and 3.0.x before 3.0.2a, trims certain directory names down to absolute paths…
Noroxi assessment
Priority: Monitor (action score 31/100)
- 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: 4.8% (FIRST EPSS); higher than 92.1% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: samba (Debian:12) 3.0.6-1; samba (Debian:3.0) 2.2.3a-14.1.
Low priority for now. Upgrade to samba (Debian:12) 3.0.6-1; samba (Debian:3.0) 2.2.3a-14.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
The unix_clean_name function in Samba 2.2.x through 2.2.11, and 3.0.x before 3.0.2a, trims certain directory names down to absolute paths, which could allow remote attackers to bypass the specified share restrictions and read, write, or list arbitrary files via "/.////" style sequences in pathnames.
