Description

This security bulletin contains information about 4 vulnerabilities.


1) Improper restriction of excessive authentication attempts (CVE-ID: CVE-2019-13918)

CWE-ID: CWE-307 - Improper Restriction of Excessive Authentication Attempts

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


The vulnerability allows a remote attacker to gain access to the web interface.

The vulnerability exists due to the web interface has no means to prevent password guessing attacks. A remote attacker can gain full access to the web interface.

2) Cross-site request forgery (CVE-ID: CVE-2019-13920)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

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

A remote attacker who is able to trigger requests of a logged-in user to the application can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website, such as switching the connectivity state of a user or a device.


3) Use of password hash with insufficient computational effort (CVE-ID: CVE-2019-13922)

CWE-ID: CWE-916 - Use of Password Hash With Insufficient Computational Effort

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


The vulnerability allows a remote attacker to access to privileged user and device information.

The vulnerability exists due to the software generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort. A remote authenticated administrator can obtain the hash of a connected device’s password.

4) Information disclosure (CVE-ID: CVE-2019-13919)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

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


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to improper access restriction on some pages. A remote authenticated attacker with valid credentials for the web interface can gain unauthorized read access to sensitive information on the system.

Note: The information affected by this vulnerability does not include passwords.
