The Kubernetes kube-apiserver in versions v1.6-v1.15, and versions prior to v1.16.13, v1.17.9 and v1.18.6 are vulnerable to an unvalidated redirect on proxied upgrade requests that could allow an attacker to escalate privileges from a node compromise to a full cluster compromise.

Vulnerability in the Oracle Database - Enterprise Edition component of Oracle Database Server. Supported versions that are affected are 12.1.0.2, 12.2.0.1, 18c and 19c. Easily exploitable vulnerability allows high privileged attacker having DBA role account privilege with network access via Oracle Net to compromise Oracle Database - Enterprise Edition. While the vulnerability is in Oracle Database - Enterprise Edition, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Database - Enterprise Edition accessible data. CVSS 3.1 Base Score 4.1 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:L/A:N).

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Security: Roles). Supported versions that are affected are 8.0.20 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Server accessible data. CVSS 3.1 Base Score 4.9 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N).

In Conjur OSS Helm Chart before 2.0.0, a recently identified critical vulnerability resulted in the installation of the Conjur Postgres database with an open port. This allows an attacker to gain full read & write access to the Conjur Postgres database, including escalating the attacker's privileges to assume full control. A malicious actor who knows the IP address and port number of the Postgres database and has access into the Kubernetes cluster where Conjur runs can gain full read & write access to the Postgres database. This enables the attacker to write a policy that allows full access to retrieve any secret. This Helm chart is a method to install Conjur OSS into a Kubernetes environment. Hence, the systems impacted are only Conjur OSS systems that were deployed using this chart. Other deployments including Docker and the CyberArk Dynamic Access Provider (DAP) are not affected. To remediate this vulnerability, clone the latest Helm Chart and follow the upgrade instructions. If you...

HashiCorp Vault and Vault Enterprise logged proxy environment variables that potentially included sensitive credentials. Fixed in 1.3.6 and 1.4.2.

The Kubernetes kube-controller-manager in versions v1.0-1.14, versions prior to v1.15.12, v1.16.9, v1.17.5, and version v1.18.0 are vulnerable to a Server Side Request Forgery (SSRF) that allows certain authorized users to leak up to 500 bytes of arbitrary information from unprotected endpoints within the master's host network (such as link-local or loopback services).

Clusters using Calico (version 3.14.0 and below), Calico Enterprise (version 2.8.2 and below), may be vulnerable to information disclosure if IPv6 is enabled but unused. A compromised pod with sufficient privilege is able to reconfigure the node’s IPv6 interface due to the node accepting route advertisement by default, allowing the attacker to redirect full or partial network traffic from the node to the compromised pod.

A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows malicious containers in Kubernetes clusters to perform man-in-the-middle (MitM) attacks. A malicious container can exploit this flaw by sending rogue IPv6 router advertisements to the host or other containers, to redirect traffic to the malicious container.

Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior (such as by causing excessive memory allocation).

In affected Ops Manager versions there is an exposed http route was that may allow attackers to view a specific access log of a publicly exposed Ops Manager instance. This issue affects: MongoDB Inc. MongoDB Ops Manager 4.0 versions 4.0.9, 4.0.10 and MongoDB Ops Manager 4.1 version 4.1.5.
