Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Stored cross-site scripting (CVE-ID: CVE-2021-21684)

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

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can inject 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.


2) Incorrect permission assignment for critical resource (CVE-ID: CVE-2022-0532)

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

The vulnerability exists due to incorrect sysctls validation in CRI-O. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace.


3) Improper Certificate Validation (CVE-ID: CVE-2014-3577)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to improper certificate validation. A remote attacker can perform a man-in-the-middle (MitM) attack and spoof SSL servers via a "CN=" string in a field in the distinguished name (DN) of a certificate.


4) Type Confusion (CVE-ID: CVE-2021-41190)

The vulnerability allows a remote attacker to compromise the system.

The vulnerability exists due to a type confusion error. A remote authenticated attacker can pass specially crafted data to the application, trigger a type confusion error and interpret the resulting content differently.


5) Resource exhaustion (CVE-ID: CVE-2021-44717)

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

The vulnerability exists due to application does not properly control consumption of internal resources when processing HTTP/2 requests. A remote attacker can send multiple HTTP/2 requests to the server and exhaust all available memory resources.


6) Input validation error (CVE-ID: CVE-2021-44716)

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.


7) Input validation error (CVE-ID: CVE-2012-6153)

The vulnerability allows a remote attacker to modify files on the system.

The vulnerability exists due to Apache Commons HttpClient does not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate. A remote attacker can pass specially crafted input to the application and modify files on the system.
