Security Bulletin

This security bulletin contains information about 9 vulnerabilities.

1) Cross-site scripting

EUVDB-ID: #VU56022

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-33195

CWE-ID: -

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of data passed from DNS lookups. A remote attacker can send a specially crafted DNS reqponse and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

OpenShift Virtualization: before 4.10.0

Q & A

Can this vulnerability be exploited remotely?

Is there known malware, which exploits this vulnerability?

2) Input validation error

EUVDB-ID: #VU56829

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-29923

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to insufficient validation of user-supplied input in net.ParseIP and net.ParseCIDR, as the Go interpreter does not properly consider extraneous zero characters at the beginning of an IP address octet. A remote attacker can bypass access control that is based on IP addresses, because of unexpected octal interpretation.

Mitigation

Install updates from vendor's website.

3) Improper Certificate Validation

EUVDB-ID: #VU55665

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-34558

CWE-ID: CWE-295 - Improper Certificate Validation

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper certificate verification in crypto/tls package in Go when processing X.509 certificates. The application does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic.

Mitigation

Install updates from vendor's website.

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-44716

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's website.
