CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
fs: don't silently unmount busy mounts
The propagate_mount_busy() helper exists to decide whether a synchronous
can suceed. It does that by looking at the copies of the victims in the
mounts its parent propagates to. One of those functions from propagation
hell.
It skips a copy that has child mounts except for the case of a single
child mount covering the copy's root. That algorithm used to be exact.
It isn't anymore.
Originally only childless copies were unmounted during propagation.
And 1064f874abc0 ("mnt: Tuck mounts under others instead of creating
shadow/side mounts.") ended up adding covered mounts to both sides in
one go.
Along came 99b19d16471e ("mnt: In propgate_umount handle visiting mounts
in any order") and that started to unmount more than before:
[1]: A copy of a mount is unmounted when each of its children is either
its overmount or a copy of the victim itself. In the former case
the overmount gets reparented. In the latter case the copy of the
victim will end up being unmounted.
So propagate_umount() ended up being rewritten without adjusting
propagate_mount_busy(). And currently propagate_mount_busy() doesn't
look at copies of the victim that have two or more children nor a single
child that is not the overmount.
So any such copy in [1] is not checked for
references. The result is that a synchronous unmount succeeds, pulling
out a mount that is still in use.
A container can run into this with its own mounts. The host shares a
tree with the container and the host has a mount in that tree:
mount -t tmpfs none /mnt
mount --make-shared /mnt
mount -t tmpfs none /mnt/a
The container's /mnt is a slave copy of the host mount. The container
now takes a detached copy of the tree and mounts that copy beneath its
propagated copy of /mnt/a and keeps the file descriptor to the tree
open:
unshare -m --propagation unchanged
mount --make-rslave /
fd = open_tree(AT_FDCWD, "/mnt", OPEN_TREE_CLONE | AT_RECURSIVE)
move_mount(fd, "", AT_FDCWD, "/mnt/a", MOVE_MOUNT_BENEATH)
grep /mnt /proc/self/mountinfo
775 355 ... /mnt ... master:646
777 775 ... /mnt/a ... master:646
776 777 ... /mnt/a ... master:647
778 777 ... /mnt/a/a ... master:647
The now attached tree (777) is now mounted beneath the container's copy
of /mnt/a. That's also where the host mount sits (as seen from the host
mount namespace). So the propagated copy (776) of the host's mount is on
top of its root and the copy of that (778) is inside it. Now the host
runs:
umount /mnt/a
and it succeeds. The moved tree tree and the copy inside of it are gone
from the container. Now only the propagated copy is left and it got
reparented to where it was before:
grep /mnt /proc/self/mountinfo
775 355 ... /mnt ... master:646
776 775 ... /mnt/a ...
But the file descriptor still refers to the moved tree. So a synchronous
umount detached a mount that is still in use.
Teach propagate_mount_busy() the same checks that propagate_umount()
does. It now checks for a single victim mount without children
for which it can assume that MNT_LOCKED is cleared on every copy like
propagate_umount() does. The copies form chains. IOW, when a copy itself
receives propagation from the victim's parent then the mount at the same
mountpoint inside that copy is a copy as well. Whether a mount receives
propagation from the victim's can simply be checked by walking its
masters. Walk each chain once from its top so we are sure that nested
copies stay linear. Check every reference once of every copy that gets
unmounted. |
| Hyland Desktop Host for Windows before 25.1.1 is vulnerable to local privilege escalation. This is caused by a privileged service running from the %PROGRAMDATA%\Hyland\DesktopHost\bin folder with weak permissions. A local user can exploit this to escalate privileges. |
| An incorrect permission assignment vulnerability in the WatchGuard Agent's log directory allows a local, authenticated non-administrative user to create, modify, append to, or delete the agent's log files and write other files into the directory. This allows an attacker to tamper with or destroy the agent's security logs and stage further local attacks by placing executable content in a directory owned by a privileged service. |

| Incorrect default permissions in the Windows installer of Progressive Robot hMailServer 6.0.0 through 6.3.6 allow a local authenticated user to run code as the mail server's high-privileged accounts when the product is installed in a folder whose permissions are inherited from a writable parent, such as the root of a drive. The installer places the server's programs in the Bin folder of the program folder and gives neither the program folder nor Bin any permissions of their own, so they inherit the parent's. Under the default location, Program Files, ordinary users receive only read and execute and the configuration is not affected; but the installer accepts any path without warning, and a program folder at the root of an NTFS volume inherits write access for a broad group - Authenticated Users (Modify) on a Windows client, Users (create files and folders) on Windows Server. A local user without administrator rights can then alter or replace the service program, which runs as LocalSystem or as the service's virtual account, or the programs an administrator runs elevated from Bin during setup and maintenance, or place a library in Bin that those programs load in place of the system copy, gaining code execution with those privileges. The default Program Files installation is not affected. |
| Incorrect Default Permissions vulnerability in Apache Camel PQC component.
This issue affects Apache Camel: from 4.12.0 before 4.18.5, from 4.19.0 before 4.22.1.
When the component wrote generated key material to disk it did so with the permissions the process default umask produced, rather than restricting the file to its owner. On a host whose umask allows group or world read, the private key was therefore readable by other local accounts. The exposure is to a local party rather than to the remote sender that the Camel threat model treats as the primary adversary, which is why the severity is assessed low, but the consequence where it applies is complete: possession of the private key defeats every signature and key exchange the deployment performs with it.
Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. Key material is now written with owner-only permissions. For deployments that cannot upgrade immediately, place the key directory on a path only the service account can traverse, and tighten the process umask. Key material already written with permissive permissions should be treated as exposed and rotated. |
| Mitigation bypass in the File Handling component. This vulnerability was fixed in Firefox ESR 153.5 and Thunderbird 153.5. |
| Incorrect default permission in Samsung Flow prior to version 4.9.22.4 allows local attackers to launch an arbitrary activity with Samsung Flow privileges on the connected device. |
| obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. Prior to 1.3.1, undefined readPaths and writePaths settings allow all paths, strictReadDefault does not protect direct requests, and the .obsidian, .git, and .trash control directories are excluded only during enumeration. An authenticated caller can directly read sensitive files such as .obsidian/plugins/*/data.json, potentially exposing plugin API keys, Obsidian Sync passwords, and other in-vault data. Version 1.3.1 fixes the vulnerability by denying the control directories by default and enforcing strictReadDefault on direct request paths. |
| Incorrect default permissions in Windows Server Update Service allows an authorized attacker to elevate privileges locally. |
| When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended. |
| Vulnerability due to incorrect permissions in TSplus Remote Access shared login scripts. The autostart1.tscr files, located in the shared themes directory, allow users without sufficient privileges to write to them. A local attacker with a valid session on the terminal or remote desktop server could modify these files to execute arbitrary commands within another user’s security context when that user logs in using the same theme or operating mode. Depending on the affected user’s privileges, exploitation could allow lateral movement between users or privilege escalation. |
| FreeRDP from 2.0.0 before 3.32.0 contains an insecure permission vulnerability in winpr-makecert that creates unencrypted private keys without owner-only file modes. Local users on multi-user Unix hosts can read world-readable key files or open PFX files protected by the hard-coded default password to steal private keys. |
| A container privilege escalation flaw was found in certain Ansible Automation Platform images. This issue arises from the /etc/passwd file being created with group-writable permissions during the build process. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This vulnerability allows an attacker to add a new user with any arbitrary UID, including UID 0, gaining full root privileges within the container. |
| ZTE Z80 Ultra has an interface permission validation vulnerability. The callable functions provided by the system lack sufficient access control. An attacker can leverage these functions to read relevant information. |
| Insecure file permissions in the CodeCatalyst connection handler in AWS Toolkit for VS Code before 4.10.0 allowed local users to obtain CodeCatalyst bearer tokens via reading world-readable token cache files.
To mitigate this issue, users should upgrade to version 4.10.0 or later. |
| A vulnerability in the client update process of Cisco AnyConnect Secure Mobility Client Software for Windows and Cisco Secure Client Software for Windows could allow a low-privileged, authenticated, local attacker to elevate privileges to those of SYSTEM. The client update process is executed after a successful VPN connection is established.
This vulnerability exists because improper permissions are assigned to a temporary directory that is created during the update process. An attacker could exploit this vulnerability by abusing a specific function of the Windows installer process. A successful exploit could allow the attacker to execute code with SYSTEM privileges. |
| In Gradle before version 7.0, on Unix-like systems, the system temporary directory can be created with open permissions that allow multiple users to create and delete files within it. Gradle builds could be vulnerable to a local privilege escalation from an attacker quickly deleting and recreating files in the system temporary directory. This vulnerability impacted builds using precompiled script plugins written in Kotlin DSL and tests for Gradle plugins written using ProjectBuilder or TestKit. If you are on Windows or modern versions of macOS, you are not vulnerable. If you are on a Unix-like operating system with the "sticky" bit set on your system temporary directory, you are not vulnerable. The problem has been patched and released with Gradle 7.0. As a workaround, on Unix-like operating systems, ensure that the "sticky" bit is set. This only allows the original user (or root) to delete a file. If you are unable to change the permissions of the system temporary directory, you can move the Java temporary directory by setting the System Property `java.io.tmpdir`. The new path needs to limit permissions to the build user only. For additional details refer to the referenced GitHub Security Advisory. |
