Noroxi assessment
Priority: Monitor (action score 33/100)
- 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: 1.8% (FIRST EPSS); higher than 78.1% of all records.
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
MailEnable Enterprise Premium 10.23 was vulnerable to multiple directory traversal issues, with which authenticated users could add, remove, or potentially read files in arbitrary folders accessible by the IIS user. This could lead to reading other users' credentials including those of SYSADMIN accounts, reading other users' emails, or adding emails or files to other users' accounts.

Root cause
A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
