ghostscript: Safer mode bypass by .forceput exposure in .pdfexectoken and other procedures (701450)

A flaw was found in, ghostscript versions prior to 9.50, in the .pdfexectoken and other procedures where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

ghostscript: Safer mode bypass by .forceput exposure in setsystemparams (701443)

A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

ghostscript: Safer mode bypass by .forceput exposure in .pdf_hook_DSC_Creator (701445)

A flaw was found in, ghostscript versions prior to 9.50, in the .pdf_hook_DSC_Creator procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

edk2: DxeImageVerificationHandler() fails open in case of dbx signature check

Logic issue in DxeImageVerificationHandler() for EDK II may allow an authenticated user to potentially enable escalation of privilege via local access.

On NXP Kinetis KV1x, Kinetis KV3x, and Kinetis K8x devices, Flash Access Controls (FAC) (a software IP protection method for execute-only access) can be defeated by observing CPU registers and the effect of code/instruction execution.

On STMicroelectronics STM32L0, STM32L1, STM32L4, STM32F4, STM32F7, and STM32H7 devices, Proprietary Code Read Out Protection (PCROP) (a software IP protection method) can be defeated by observing CPU registers and the effect of code/instruction execution.

chromium-browser: Service worker state error

Insufficient policy enforcement in service workers in Google Chrome prior to 78.0.3904.70 allowed a remote attacker to bypass navigation restrictions via a crafted HTML page.

search-guard: information disclosure in field level security (FLS)

Search Guard versions before 24.0 had an issue that field caps and mapping API leak field names (but not values) for fields which are not allowed for the user when field level security (FLS) is activated.

In CentOS-WebPanel.com (aka CWP) CentOS Web Panel 0.9.8.846, a hidden action=9 feature in filemanager2.php allows attackers to execute a shell command, i.e., obtain a reverse shell with user privilege.

In WESEEK GROWI before 3.5.0, the site-wide basic authentication can be bypassed by adding a URL parameter access_token (this is the parameter used by the API). No valid token is required since it is not validated by the backend. The website can then be browsed as if no basic authentication is required.

An issue was discovered in GitLab Community and Enterprise Edition 11.9 and later through 12.0.2. GitLab Snippets were vulnerable to an authorization issue that allowed unauthorized users to add comments to a private snippet. It allows authentication bypass.

The Java API in accesuniversitat.gencat.cat 1.7.5 allows remote attackers to get personal information of all registered students via several API endpoints.

Cisco IOS XE Software Consent Token Bypass Vulnerability

A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker to gain shell access on an affected device and execute commands on the underlying operating system (OS). The vulnerability is due to insufficient enforcement of the consent token in authorizing shell access. An attacker could exploit this vulnerability by authenticating to the CLI and requesting shell access on an affected device. A successful exploit could allow the attacker to gain shell access on the affected device and execute commands on the underlying OS.

Cisco IOx for IOS Software Guest Operating System Unauthorized Access Vulnerability

A vulnerability in the IOx application environment for Cisco IOS Software could allow an authenticated, remote attacker to gain unauthorized access to the Guest Operating System (Guest OS) running on an affected device. The vulnerability is due to incorrect role-based access control (RBAC) evaluation when a low-privileged user requests access to a Guest OS that should be restricted to administrative accounts. An attacker could exploit this vulnerability by authenticating to the Guest OS by using the low-privileged-user credentials. An exploit could allow the attacker to gain unauthorized access to the Guest OS as a root user.

Gallagher Command Centre before 7.80.939, 7.90.x before 7.90.961, and 8.x before 8.00.1128 allows arbitrary event creation and information disclosure via the FT Command Centre Service and FT Controller Service services.

cxf: OpenId Connect token service does not properly validate the clientId

Apache CXF before 3.3.4 and 3.2.11 provides all of the components that are required to build a fully fledged OpenId Connect service. There is a vulnerability in the access token services, where it does not validate that the authenticated principal is equal to that of the supplied clientId parameter in the request. If a malicious client was able to somehow steal an authorization code issued to another client, then they could exploit this vulnerability to obtain an access token for the other client.

Mozilla: Retired site input.mozilla.org has remote troubleshooting permissions

Application permissions give additional remote troubleshooting permission to the site input.mozilla.org, which has been retired and now redirects to another site. This additional permission is unnecessary and is a potential vector for malicious attacks. This vulnerability affects Firefox < 68.

Zoho ManageEngine Remote Access Plus 10.0.258 does not validate user permissions properly, allowing for privilege escalation and eventually a full application takeover.

CAPI leaks service broker URLs and GUIDs to space developers

Cloud Foundry Cloud Controller API (CAPI), version 1.88.0, allows space developers to list all global service brokers, including service broker URLs and GUIDs, which should only be accessible to admins.

Kubernetes kube-apiserver allows access to custom resources via wrong scope

The Kubernetes kube-apiserver mistakenly allows access to a cluster-scoped custom resource if the request is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are enforced using roles and role bindings within the namespace, meaning that a user with access only to a resource in one namespace could create, view update or delete the cluster-scoped resource (according to their namespace role privileges). Kubernetes affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions prior to 1.15.2, and versions 1.7, 1.8, 1.9, 1.10, 1.11, 1.12.
