Description
This security bulletin contains information about 6 vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2021-33195)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Green
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.
2) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2020-8565)
CWE-ID: CWE-532 - Information Exposure Through Log Files
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to authorization and bearer tokens will be written to log files if the logging level is set to at least 9. A local user can read the log files and gain access to sensitive data.
3) Resource management error (CVE-ID: CVE-2021-33198)
CWE-ID: CWE-399 - Resource Management Errors
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:Green
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.
4) Missing Authorization (CVE-ID: CVE-2021-33197)
CWE-ID: CWE-862 - Missing Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
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.
5) Improper Certificate Validation (CVE-ID: CVE-2021-34558)
CWE-ID: CWE-295 - Improper Certificate Validation
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:P/U:Green
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.
6) Unprotected storage of credentials (CVE-ID: CVE-2019-11250)
CWE-ID: CWE-256 - Unprotected Storage of Credentials
CVSSv4: CVSS:4.0/AV:L/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 local user to gain access to other users' credentials.
The vulnerability exists due Kubernetes client-go library logs request headers at verbosity levels of 7 or higher. This can disclose credentials to unauthorized users via logs or command output. Kubernetes components (such as kube-apiserver) prior to v1.16.0, which make use of basic or bearer token authentication, and run at high verbosity levels, are affected. A local user can view contents of the configuration file and gain access to passwords for 3rd party integration.
