CVE-2025-34171CasaOS <= 0.4.15 Unauthenticated File and Debug Data Exposure
Medium 6.9
In plain English
A medium-severity missing authorization in CasaOS from IceWhale Tech. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.7% (higher than 53% of all known vulnerabilities). Ready-made attack tooling exists: public proof-of-concept code.
Official description
CasaOS versions up to and including 0.4.15 expose multiple unauthenticated endpoints that allow remote attackers to retrieve sensitive configuration files and system debug information. The /v1/users/image endpoint can be abused with a user-controlled path parameter to access files under /var/lib/casaos/1/, which reveals installed applications and configuration details. Additionally, /v1/sys/debug discloses host operating system, kernel, hardware, and storage information. The endpoints also return distinct error messages, enabling file existence enumeration of arbitrary paths on the underlying host filesystem. This information disclosure can be used for reconnaissance and to facilitate targeted follow-up attacks against services deployed on the host.
