Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Cross-site scripting

EUVDB-ID: #VU56022

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-33195

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

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

kubevirt (Red Hat package): 4.8.3-251.el7 - 4.8.3-251.el8

OpenShift Virtualization: before 4.8.5

CPE2.3 External links

http://access.redhat.com/errata/RHSA-2022:1329

Q & A

Can this vulnerability be exploited remotely?

Is there known malware, which exploits this vulnerability?

EUVDB-ID: #VU56023

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-33197

CWE-ID: CWE-862 - Missing Authorization

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authorization process.

The vulnerability exists due to an error in some configurations of ReverseProxy (from net/http/httputil). A remote attacker can drop arbitrary headers and bypass authorization process. 

Mitigation

Install updates from vendor's website.

Vulnerable software versions

kubevirt (Red Hat package): 4.8.3-251.el7 - 4.8.3-251.el8

3) Resource management error

EUVDB-ID: #VU56024

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-33198

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

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

The vulnerability exists due to improper management of internal resources within the application when handling a large exponent to the math/big.Rat SetString or UnmarshalText method.  A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

kubevirt (Red Hat package): 4.8.3-251.el7 - 4.8.3-251.el8

4) 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.
