Security Bulletin
This security bulletin contains information about 7 vulnerabilities.
1) Resource exhaustion
EUVDB-ID: #VU22824
Risk: Medium
CVSSv4.0: 6.6 [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]
CVE-ID: CVE-2019-11253
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation when processing YAML or JSON data in Kubernetes API server. A remote attacker can pass a malicious file to the API server and consume excessive memory and CPU resources, leading to a denial of service (DoS) attack.
Note, this vulnerability can be exploited by a remote non-authenticated attacker in Kubernetes versions prior to 1.14.0 due to default RBAC policy.

5) Cross-site scripting
EUVDB-ID: #VU27396
Risk: Medium
CVSSv4.0: 1.2 [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]
CVE-ID: CVE-2020-12245
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
