What is CVE-2025-34171?
CVE-2025-34171 is a medium-severity vulnerability in IceWhale Tech CasaOS, published on 3 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
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.
