ovirt-engine: Redirect to arbitrary URL allows for phishing

An Open redirect vulnerability was found in ovirt-engine versions 4.4 and earlier, where it allows remote attackers to redirect users to arbitrary web sites and attempt phishing attacks. Once the target has opened the malicious URL in their browser, the critical part of the URL is no longer visible. The highest threat from this vulnerability is on confidentiality.

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.

QEMU: nbd: reachable assertion failure in nbd_negotiate_send_rep_verr via remote client

An assertion failure issue was found in the Network Block Device(NBD) Server in all QEMU versions before QEMU 5.0.1. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service.

dpdk: librte_vhost Malicious guest could cause segfault by sending invalid Virtio descriptor

A flaw was found in DPDK version 19.11 and above that allows a malicious guest to cause a segmentation fault of the vhost-user backend application running on the host, which could result in a loss of connectivity for the other guests running on that host. This is caused by a missing validity check of the descriptor address in the function `virtio_dev_rx_batch_packed()`.

Tower: OAuth2 refresh tokens do not respect the expiration

A security flaw was found in Ansible Tower when requesting an OAuth2 token with an OAuth2 application. Ansible Tower uses the token to provide authentication. This flaw allows an attacker to obtain a refresh token that does not expire. The original token granted to the user still has access to Ansible Tower, which allows any user that can gain access to the token to be fully authenticated to Ansible Tower. This flaw affects Ansible Tower versions before 3.6.4 and Ansible Tower versions before 3.5.6.

samba: LDAP Denial of Service (stack overflow) in Samba AD DC

A flaw was found when using samba as an Active Directory Domain Controller. Due to the way samba handles certain requests as an Active Directory Domain Controller LDAP server, an unauthorized user can cause a stack overflow leading to a denial of service. The highest threat from this vulnerability is to system availability. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2.

WebAccess/NMS (versions prior to 3.0.2) does not sanitize XML input. Specially crafted XML input could allow an attacker to read sensitive files.

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.

Multiple session validity check issues in several administration functionalities of Invigo Automatic Device Management (ADM) through 5.0 allow remote attackers to read potentially sensitive data hosted by the application.

An issue was discovered in Janus through 0.9.1. janus_audiobridge.c has a double mutex unlock when listing private rooms in AudioBridge.

RVD#3323: Mismanaged permission implementation leads to privilege escalation, exfiltration of sensitive information, and DoS

the main user account has restricted privileges but is in the sudoers group and there is not any mechanism in place to prevent sudo su or sudo -i to be run gaining unrestricted access to sensible files, encryption, or issue orders that disrupt robot operation.

RVD#3321: No Authentication required to exert manual control of the robot

No authentication is required to control the robot inside the network, moreso the latest available user manual shows an option that lets the user to add a password to the robot but as in xarm_studio 1.3.0 the option is missing from the menu. Assuming manual control, even by forcefully removing the current operator from an active session.

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.

RVD#2555: MiR ROS computational graph is exposed to all network interfaces, including poorly secured wireless networks and open wired ones

MiR100, MiR200 and other MiR robots use the Robot Operating System (ROS) default packages exposing the computational graph to all network interfaces, wireless and wired. This is the result of a bad set up and can be mitigated by appropriately configuring ROS and/or applying custom patches as appropriate. Currently, the ROS computational graph can be accessed fully from the wired exposed ports. In combination with other flaws such as CVE-2020-10269, the computation graph can also be fetched and interacted from wireless networks. This allows a malicious operator to take control of the ROS logic and correspondingly, the complete robot given that MiR's operations are centered around the framework (ROS).

An issue was discovered in Joomla! before 3.9.16. Various actions in com_templates lack the required ACL checks, leading to various potential attack vectors.

Macrium Reflect includes an OpenSSL component that specifies an OPENSSLDIR variable as C:\openssl\. Macrium Reflect contains a privileged service that uses this OpenSSL component. Because unprivileged Windows users can create subdirectories off of the system root, a user can create the appropriate path to a specially-crafted openssl.cnf file to achieve arbitrary code execution with SYSTEM privileges.

Acronis True Image 2021 includes an OpenSSL component that specifies an OPENSSLDIR variable as a subdirectory within C:\jenkins_agent\. Acronis True Image contains a privileged service that uses this OpenSSL component. Because unprivileged Windows users can create subdirectories off of the system root, a user can create the appropriate path to a specially-crafted openssl.cnf file to achieve arbitrary code execution with SYSTEM privileges.

Acronis Cyber Backup 12.5 and Cyber Protect 15 include an OpenSSL component that specifies an OPENSSLDIR variable as a subdirectory within C:\jenkins_agent\. Acronis Cyber Backup and Cyber Protect contain a privileged service that uses this OpenSSL component. Because unprivileged Windows users can create subdirectories off of the system root, a user can create the appropriate path to a specially-crafted openssl.cnf file to achieve arbitrary code execution with SYSTEM privileges.

CVE-2020-10130

SearchBlox before Version 9.1 is vulnerable to business logic bypass where the user is able to create multiple super admin users in the system.

GitLab 8.11 through 12.8.1 allows a Denial of Service when using several features to recursively request eachother,
