MCE: Potential Cluster Level Privilege Escalation In Open Cluster Management

A flaw was found in the Open Cluster Management (OCM) when a user have access to the worker nodes which has the cluster-manager-registration-controller or cluster-manager deployments. A malicious user can take advantage of this and bind the cluster-admin to any service account or using the service account to list all secrets for all kubernetes namespaces, leading into a cluster-level privilege escalation.

Privilege Chaining in GitLab

A privilege escalation vulnerability was discovered in GitLab affecting versions 16.8 prior to 16.8.4 and 16.9 prior to 16.9.2. It was possible for a user with custom role of `manage_group_access_tokens` to rotate group access tokens with owner privileges.

Sysadmin can override existing configs & bypass restrictions like EnableUploads

One of the API in Mattermost version 6.3.0 and earlier fails to properly protect the permissions, which allows the system administrators to combine the two distinct privileges/capabilities in a way that allows them to override certain restricted configurations like EnableUploads.

Command Authentication Bypass in Z/IP Gateway

A logic error in SiLabs Z/IP Gateway SDK 7.18.02 and earlier allows authentication to be bypassed, remote administration of Z-Wave controllers, and S0/S2 encryption keys to be recovered.

Privilege Chaining in hestiacp/hestiacp

Privilege Chaining in GitHub repository hestiacp/hestiacp prior to 1.8.9.

A vulnerability in the ERS API of Cisco ISE could allow an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device. To exploit this vulnerability, an attacker must have valid Administrator-level privileges on the affected device. This vulnerability is due to improper privilege management in the ERS API. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to elevate their privileges beyond the sphere of their intended access level, which would allow them to obtain sensitive information from the underlying operating system. Note: The ERS is not enabled by default. To verify the status of the ERS API in the Admin GUI, choose Administration > Settings > API Settings > API Service Settings.

xen: a malicious PV guest administrator may be able to escalate their privilege to that of the host

An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to gain host OS privileges by leveraging race conditions in pagetable promotion and demotion operations. There are issues with restartable PV type change operations. To avoid using shadow pagetables for PV guests, Xen exposes the actual hardware pagetables to the guest. In order to prevent the guest from modifying these page tables directly, Xen keeps track of how pages are used using a type system; pages must be "promoted" before being used as a pagetable, and "demoted" before being used for any other type. Xen also allows for "recursive" promotions: i.e., an operating system promoting a page to an L4 pagetable may end up causing pages to be promoted to L3s, which may in turn cause pages to be promoted to L2s, and so on. These operations may take an arbitrarily large amount of time, and so must be re-startable. Unfortunately, making recursive pagetable promotion and demotion operations restartable is incredibly complicated, and the code contains several races which, if triggered, can cause Xen to drop or retain extra type counts, potentially allowing guests to get write access to in-use pagetables. A malicious PV guest administrator may be able to escalate their privilege to that of the host. All x86 systems with untrusted PV guests are vulnerable. HVM and PVH guests cannot exercise this vulnerability.

hadoop: Privilege escalation to root (Incomplete fix for CVE-2016-6811)

In Apache Hadoop 2.7.4 to 2.7.6, the security fix for CVE-2016-6811 is incomplete. A user who can escalate to yarn user can possibly run arbitrary commands as root user.
