Improper URL validation in GreenBrowser

GreenBrowser before version 1.2 has a vulnerability where apps that rely on URL Parsing to verify that a given URL is pointing to a trust server may be susceptible to many different ways to get URL parsing and verification wrong, which allows an attacker to circumvent the access control. This problem has been patched in version 1.2.

In the Password Reset Module in VESTA Control Panel through 0.9.8-25 and Hestia Control Panel before 1.1.1, Host header manipulation leads to account takeover because the victim receives a reset URL containing an attacker-controlled server name.

In PowerShell App Deployment Toolkit (aka PSAppDeployToolkit) through 3.8.0, an incorrect access control vulnerability in the default configuration may allow an authenticated user to potentially enable escalation of privilege via local access.

This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of NETGEAR R6700 V1.0.4.84_10.0.58 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of URLs. The issue results from the lack of proper routing of URLs. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-9618.

This vulnerability allows a firewall bypass on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of IPv6 connections. The issue results from the lack of proper filtering of IPv6 SSH connections. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-9663.

kernel: kernel stack information leak on s390/s390x

A stack information leak flaw was found in s390/s390x in the Linux kernel’s memory manager functionality, where it incorrectly writes to the /proc/sys/vm/cmm_timeout file. This flaw allows a local user to see the kernel data.

containernetworking/plugins: IPv6 router advertisements allow for MitM attacks on IPv4 clusters

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.

Infinispan: REST and HotRod APIs unsecured locally by default

A flaw was found in Infinispan (org.infinispan:infinispan-server-runtime) version 10, where it permits local access to controls via both REST and HotRod APIs. This flaw allows a user authenticated to the local machine to perform all operations on the caches, including the creation, update, deletion, and shutdown of the entire server.

ceph: authorization bypass in monitor and manager daemons

An authorization bypass vulnerability was found in Ceph versions 15.2.0 before 15.2.2, where the ceph-mon and ceph-mgr daemons do not properly restrict access, resulting in gaining access to unauthorized resources. This flaw allows an authenticated client to modify the configuration and possibly conduct further attacks.

wildfly: exposed setting of TCCL via the EmbeddedManagedProcess API

A flaw was found in Wildfly before wildfly-embedded-13.0.0.Final, where the embedded managed process API has an exposed setting of the Thread Context Classloader (TCCL). This setting is exposed as a public method, which can bypass the security manager. The highest threat from this vulnerability is to confidentiality.

rubygem-foreman_ansible: "User input" entry from Job Invocation may contain sensitive data

A flaw was found in Red Hat Satellite's Job Invocation, where the "User Input" entry was not properly restricted to the view. This flaw allows a malicious Satellite user to scan through the Job Invocation, with the ability to search for passwords and other sensitive data. This flaw affects tfm-rubygem-foreman_ansible versions before 4.0.3.4.

qemu: weak signature generation in Pointer Authentication support for ARM

A flaw was found in QEMU in the implementation of the Pointer Authentication (PAuth) support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all programs running on QEMU.

Tower: normal users can intercept stdout from jobs running in other organizations

A flaw was found in Ansible Tower when running jobs. This flaw allows an attacker to access the stdout of the executed jobs which are run from other organizations. Some sensible data can be disclosed. However, critical data should not be disclosed, as it should be protected by the no_log flag when debugging is enabled. This flaw affects Ansible Tower versions before 3.6.4, Ansible Tower versions before 3.5.6 and Ansible Tower versions before 3.4.6.

Tower: memcached deployment is insecure on OpenShift

A flaw was found in Ansible Tower when running Openshift. Tower runs a memcached, which is accessed via TCP. An attacker can take advantage of writing a playbook polluting this cache, causing a denial of service attack. This attack would not completely stop the service, but in the worst-case scenario, it can reduce the Tower performance, for which memcached is designed. Theoretically, more sophisticated attacks can be performed by manipulating and crafting the cache, as Tower relies on memcached as a place to pull out setting values. Confidential and sensitive data stored in memcached should not be pulled, as this information is encrypted. This flaw affects Ansible Tower versions before 3.6.4, Ansible Tower versions before 3.5.6 and Ansible Tower versions before 3.4.6.

che: pods in kubernetes cluster can bypass JWT proxy and send unauthenticated requests to workspace pods

A flaw was found in the Eclipse Che up to version 7.8.x, where it did not properly restrict access to workspace pods. An authenticated user can exploit this flaw to bypass JWT proxy and gain access to the workspace pods of another user. Successful exploitation requires knowledge of the service name and namespace of the target pod.

keycloak: remove other users MFA devices

A flaw was found in Keycloak version 8.0.2 and 9.0.0, and was fixed in Keycloak version 9.0.1, where a malicious user registers as oneself. The attacker could then use the remove devices form to post different credential IDs and possibly remove MFA devices for other users.

Insulet Omnipod Insulin Management System insulin pump product ID 19191 and 40160 is designed to communicate using a wireless RF with an Insulet manufactured Personal Diabetes Manager device. This wireless RF communication protocol does not properly implement authentication or authorization. An attacker with access to one of the affected insulin pump models may be able to modify and/or intercept data. This vulnerability could also allow attackers to change pump settings and control insulin delivery.

In BD Pyxis MedStation ES System v1.6.1 and Pyxis Anesthesia (PAS) ES System v1.6.1, a restricted desktop environment escape vulnerability exists in the kiosk mode functionality of affected devices. Specially crafted inputs could allow the user to escape the restricted environment, resulting in access to sensitive data.

RVD#3317: MAVLink version handshaking allows for an attacker to bypass authentication

The Micro Air Vehicle Link (MAVLink) protocol presents authentication mechanisms on its version 2.0 however according to its documentation, in order to maintain backwards compatibility, GCS and autopilot negotiate the version via the AUTOPILOT_VERSION message. Since this negotiation depends on the answer, an attacker may craft packages in a way that hints the autopilot to adopt version 1.0 of MAVLink for the communication. Given the lack of authentication capabilities in such version of MAVLink (refer to CVE-2020-10282), attackers may use this method to bypass authentication capabilities and interact with the autopilot directly.

RVD#2562: Booting from a live image leads to exfiltration of sensible information and privilege escalation

There is no mechanism in place to prevent a bad operator to boot from a live OS image, this can lead to extraction of sensible files (such as the shadow file) or privilege escalation by manually adding a new user with sudo privileges on the machine.
