The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L with a score of 7.4.
Potential Impact
Successful exploitation allows remote attackers with low privileges to execute arbitrary commands on the affected device, potentially leading to partial compromise of confidentiality, integrity, and availability. The vulnerability affects the device's administrative CGI interface, which could be leveraged to control or disrupt device operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are currently available.
