Cisco ThousandEyes Enterprise Agent Virtual Appliance version thousandeyes-va-64-18.04 0.218 suffers from an unpatched vulnerability in sudoedit, allowed by sudo configuration, which permits a low-privilege user to modify arbitrary files as root and subsequently execute arbitrary commands as root.
Red Hat Security Advisory 2023-3742-02 - Red Hat OpenShift Data Foundation is software-defined storage integrated with and optimized for the Red Hat OpenShift Container Platform. Red Hat OpenShift Data Foundation is a highly scalable, production-grade persistent storage for stateful applications running in the Red Hat OpenShift Container Platform. Issues addressed include bypass, denial of service, and remote SQL injection vulnerabilities.
[PROBLEMTYPE] in [COMPONENT] in [VENDOR] [PRODUCT] [VERSION] on [PLATFORMS] allows [ATTACKER] to [IMPACT] via [VECTOR]
This exploit takes advantage of a vulnerability in sudoedit, part of the sudo package. The sudoedit (aka sudo -e) feature mishandles extra arguments passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. by appending extra entries on /etc/sudoers allowing for execution of an arbitrary payload with root privileges. Affected versions are 1.8.0 through 1.9.12.p1. However, this module only works against Ubuntu 22.04 and 22.10. This module was tested against sudo 1.9.9-1ubuntu2 on Ubuntu 22.04 and 1.9.11p3-1ubuntu1 on Ubuntu 22.10.

Ubuntu Security Notice 5811-2 - USN-5811-1 fixed a vulnerability in Sudo. This update provides the corresponding update for Ubuntu 16.04 ESM. Matthieu Barjole and Victor Cutillas discovered that Sudo incorrectly handled user-specified editors when using the sudoedit command. A local attacker that has permission to use the sudoedit command could possibly use this issue to edit arbitrary files.
Ubuntu Security Notice 5811-1 - Matthieu Barjole and Victor Cutillas discovered that Sudo incorrectly handled user-specified editors when using the sudoedit command. A local attacker that has permission to use the sudoedit command could possibly use this issue to edit arbitrary files. It was discovered that the Protobuf-c library, used by Sudo, incorrectly handled certain arithmetic shifts. An attacker could possibly use this issue to cause Sudo to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS.
Debian Linux Security Advisory 5321-1 - Matthieu Barjole and Victor Cutillas discovered that sudoedit in sudo, a program designed to provide limited super user privileges to specific users, does not properly handle '--' to separate the editor and arguments from files to edit. A local user permitted to edit certain files can take advantage of this flaw to edit a file not permitted by the security policy, resulting in privilege escalation.
In Sudo before 1.9.12p2, the sudoedit (aka -e) feature mishandles extra arguments passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. Affected versions are 1.8.0 through 1.9.12.p1. The problem exists because a user-specified editor may contain a "--" argument that defeats a protection mechanism, e.g., an EDITOR='vim -- /path/to/extra/file' value.
