Description

This security bulletin contains information about 3 vulnerabilities.


1) Path traversal (CVE-ID: CVE-2018-13812)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to obtain potentially sensitive information.

The vulnerability exists due to directory traversal. A remote attacker with network access to the integrated web server can conduct directory traversal attack and download of arbitrary files from the device.


2) Open redirect (CVE-ID: CVE-2018-13813)

CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to redirect victims to arbitrary URI.

The vulnerability exists due to improper sanitization of user-supplied data. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary URI.

Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information


3) HTTP header injection (CVE-ID: CVE-2018-13814)

CWE-ID: CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to inject HTTP header on the target system.

The vulnerability exists due to insufficient validation of user-supplied input. A remote unauthenticated attacker can trick the victim into clicking on a malicious link and use integrated web server (Port 80/TCP and Port 443/TCP) inject HTTP headers.
