Risk: Medium
CVSSv3.1: 6.9 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2019-15276
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the web interface due to a failure of the HTTP parsing engine to handle specially crafted URLs. A remote authenticated attacker can send a specially crafted URL to the web interface of the affected device and cause a denial of service condition on the target system.
Conversely, an unauthenticated attacker could exploit this vulnerability by persuading a user of the web interface to click the crafted URL.
MitigationInstall updates from vendor's website.
