A locking protection bypass flaw was found in some versions of gnome-shell as shipped within CentOS Stream 8, when the "Application menu" or "Window list" GNOME extensions are enabled. This flaw allows a physical attacker who has access to a locked system to kill existing applications and start new ones as the locked user, even if the session is still locked.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of CentOS Web Panel cwp-e17.0.9.8.923. Authentication is not required to exploit this vulnerability. The specific flaw exists within ajax_dashboard.php. When parsing the service_stop parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-9726.

Bubblewrap (bwrap) before version 0.4.1, if installed in setuid mode and the kernel supports unprivileged user namespaces, then the `bwrap --userns2` option can be used to make the setuid process keep running as root while being traceable. This can in turn be used to gain root permissions. Note that this only affects the combination of bubblewrap in setuid mode (which is typically used when unprivileged user namespaces are not supported) and the support of unprivileged user namespaces. Known to be affected are: * Debian testing/unstable, if unprivileged user namespaces enabled (not default) * Debian buster-backports, if unprivileged user namespaces enabled (not default) * Arch if using `linux-hardened`, if unprivileged user namespaces enabled (not default) * Centos 7 flatpak COPR, if unprivileged user namespaces enabled (not default) This has been fixed in the 0.4.1 release, and all affected users should update.

In CentOS-WebPanel.com (aka CWP) CentOS Web Panel 0.9.8.851, an insecure object reference allows an attacker to delete databases (such as oauthv2) from the server via an attacker account.

In CentOS-WebPanel.com (aka CWP) CentOS Web Panel 0.9.8.851, an insecure object reference allows an attacker to discover phpMyAdmin passwords (of any user in /etc/passwd) via an attacker account.

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.

CentOS-WebPanel.com (aka CWP) CentOS Web Panel 0.9.8.793 (Free/Open Source Version) and 0.9.8.753 (Pro) is vulnerable to Stored/Persistent XSS for Admin Email fields on the "CWP Settings > "Edit Settings" screen. By changing the email ID to any XSS Payload and clicking on Save Changes, the XSS Payload will execute.

CentOS Web Panel (CWP) 0.9.8.789 is vulnerable to Stored/Persistent XSS for the "Name Server 1" and "Name Server 2" fields via a "DNS Functions" "Edit Nameservers IPs" action.
