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.

Linux distributions that have not patched their long-term kernels with https://git.kernel.org/linus/a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (committed on April 14, 2015). This kernel vulnerability was fixed in April 2015 by commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to Linux 3.10.77 in May 2015), but it was not recognized as a security threat. With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down address allocation strategy, load_elf_binary() will attempt to map a PIE binary into an address range immediately below mm->mmap_base. Unfortunately, load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are that is supposed to be the "gap" between the stack and the binary.

Unspecified vulnerability in EMC Documentum Content Server 6.0, 6.5 before SP2 P02, 6.5 SP3 before SP3 P02, and 6.6 before P02 allows local users to obtain "highest super user privileges" by leveraging system administrator privileges.
