Description

This security bulletin contains information about 6 vulnerabilities.


1) Cross-site request forgery (CVE-ID: CVE-2018-13993)

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

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


The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.


2) Security restrictions bypass (CVE-ID: CVE-2018-13990)

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

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


The vulnerability allows a remote attacker to bypass security restrictions.

The vulnerability exists due to lack of a login time-out feature to prevent high-speed automated username and password combination guessing. A remote attacker can conduct brute forcing attack against usernames and passwords and bypass security restrictions.


3) Information disclosure (CVE-ID: CVE-2018-13992)

CWE-ID: CWE-319 - Cleartext Transmission of Sensitive Information

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


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

The vulnerability exists due to default setting of the Web UI (HTTP) allows user credentials to be transmitted unencrypted. A remote attacker can gain access to these credentials.


4) Resource exhaustion (CVE-ID: CVE-2018-13994)

CWE-ID: CWE-400 - Resource exhaustion

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


The vulnerability allows a remote attacker to cause DoS condition.

The vulnerability exists due to resource exhaustion. A remote attacker can initiate a web denial-of-service attack by producing an excessive number of Web UI connections.


5) Information disclosure (CVE-ID: CVE-2018-13991)

CWE-ID: CWE-922 - Insecure Storage of Sensitive Information

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/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 obtain potentially sensitive information.

The vulnerability exists due to insecure storage of sensitive information. A remote attacker can extract the switch’s default private keys from its firmware image.


6) Out-of-bounds read (CVE-ID: CVE-2017-3735)

CWE-ID: CWE-125 - Out-of-bounds read

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


The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to one-byte out-of-bounds read when parsing an IPAddressFamily extension in an X.509 certificate. A remote attacker can disguise text display of the certificate.
