Source: CVE Database V5

Description

The locally served web site on the Garmin WDU (v1 1.4.6 and v2 5.0) allows a symlink attack. If a malicious graphics package containing symlinks is uploaded, the web server follows the supplied links when serving content. No mechanisms to restrict those link targets to a specific area of the filesystem is enabled. This allows an attacker to retrieve arbitrary files from the device.

Technical Analysis

The Garmin WDU device web server in versions v1 1.4.6 and v2 5.0 is vulnerable to a symlink attack (CWE-59). When a malicious graphics package containing symlinks is uploaded, the server follows these links when serving content. Because there are no mechanisms to restrict link targets to a specific filesystem area, an attacker can retrieve arbitrary files from the device. This vulnerability does not require privileges or user interaction and has a CVSS 3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). No patch or official remediation guidance is currently available.

Potential Impact

An attacker can retrieve arbitrary files from the Garmin WDU device by exploiting the symlink vulnerability in the web server. This leads to a high confidentiality impact as sensitive files on the device may be exposed. There is no indication of impact on integrity or availability. The vulnerability can be exploited remotely without authentication or user interaction.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the Garmin WDU web interface to trusted networks and users to reduce exposure. Avoid uploading untrusted graphics packages to the device. Monitor vendor communications for updates on patches or mitigations.
