QNAP QuMagie: Path traversal allows reading unexpected files
Summary
QuMagie, a photo management application for QNAP NAS devices, contains a relative path traversal vulnerability (CWE-23). An attacker who already holds an administrator account on QuMagie can use it to read the contents of unexpected files or system data. The CNA describes the issue as affecting QuMagie 2.9.x before 2.9.1, and the default configuration is not affected.
Affected
- QNAP QuMagie 2.9.x before 2.9.1 (according to the CNA; the CVE Daily Brief lists 2.9.x before 2.9.2, see recommendation)
- Default configuration: not affected
Fixed in
- QuMagie 2.9.1 and later (according to the CNA and QNAP's CVE record)
- Conflicting information: some sources list 2.9.2 as the fixed version; unverified
Workaround
Unknown.
Exploitation
- No evidence of exploitation in the wild found.
- CISA SSVC (ADP): exploitation none, automatable no, technical impact total.
- EPSS about 0.5%.
- No public proof of concept found; this does not rule one out.
Our recommendation
- Update QuMagie to the newest fixed version listed in QNAP's release notes (2.9.2 if in doubt), as the fixed version is conflicting across sources.
- Make sure the NAS admin interface is not exposed to the internet; use a VPN for remote access.
- Enforce strong passwords and MFA on all NAS admin accounts, and limit the number of administrators.
- Review NAS admin logins for unexpected activity.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
