CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
riscv: entry: gate shadow call stack reload on sstatus.SPP, not tp
Under CONFIG_SHADOW_CALL_STACK, handle_exception() reloads the kernel
shadow call stack pointer (gp) only when the trap came from userspace.
It made that decision with scs_load_current_if_task_changed, which
compares the trap-time tp (read back from sscratch into s5) against the
current tp:
beq \prev, tp, _skip_scs
scs_load_current
_skip_scs:
tp is a user-writable register. A user task that sets tp to the
linear-map address of its own task_struct (¤t) before trapping
makes the comparison succeed (can achieve by brute force with KASLR
enable under our test), so the kernel skips scs_load_current and
keeps running with the gp that userspace left in place. Under
CONFIG_SHADOW_CALL_STACK gp is the shadow call stack pointer and
load_global_pointer is a no-op, so the compiler-emitted
"sd ra, -8(gp)" / "ld ra, -8(gp)" in every non-leaf function then write
to, and return through, an attacker-controlled address -- an
unprivileged kernel arbitrary-write and control-flow-hijack primitive.
The poisoned gp is saved to task_struct.scs_sp on return, so the reload
is skipped on every subsequent entry as well.
Decide "came from userspace" from the hardware sstatus.SPP bit (already
in s1 at this point) instead of from tp, mirroring the check that
ret_from_exception already uses a few instructions later. SPP is
written by hardware on trap entry and cannot be forged from U-mode.
Legitimate behaviour is unchanged: user entries (SPP=0) reload the task
shadow call stack, nested kernel entries (SPP=1) skip it. |

| Postiz signs its session, invitation and password reset tokens with one shared secret and without any marker of what a token is for. A route that refreshes the credentials of a browser-extension channel signed data taken from the request itself and stored the result where the requesting user can read it back. A user could therefore obtain a validly signed token containing any claims they choose, which the application accepts as a session, as an organization invitation with a chosen role, as a password reset or as an enterprise provisioning token.
A second, narrower route that creates team invitations signs extra fields from the request body in the same way. |
| A flaw has been found in Travisun Opptrix 0.4.0. This affects an unknown function of the file /api/auth/setup of the component Schedule API. This manipulation causes command injection. It is possible to initiate the attack remotely. The exploit has been published and may be used. The project has been completely taken offline and deprecated. The project maintainer explains: "The mentioned security risk was a design flaw that manifested primarily in local environments during earlier stages of version development. We previously addressed and resolved this specific risk; however, because the project was restricted to a small learning scope and the main versions were intended to run exclusively on localhost, the security fix was only pushed directly to our GitHub repository before it went private." This vulnerability only affects products that are no longer supported by the maintainer. |
| The News Kit Addons For Elementor WordPress plugin before 1.4.9 does not perform a capability check on one of its AJAX actions, allowing authenticated users with subscriber-level access and above to install and activate a specific News Kit Addons For Elementor WordPress plugin before 1.4.9 from the WordPress.org repository. |
| The Front End Users WordPress plugin through 3.2.35 does not restrict which account attributes a visitor may set when registering through its front-end forms, allowing unauthenticated users to assign themselves an arbitrary membership level and to mark their own account as approved, confirmed and paid, bypassing the Front End Users WordPress plugin through 3.2.35's content restrictions and its registration gating. |
| Postiz lets a signed-in user ask the backend to run a function on one of their connected channels. The backend did not restrict which functions can be requested, so a user could call internal helper functions that were never meant to be reachable from the web interface.
One of those helpers reads a file from the server's disk. A user who connects a channel whose stored token is a file path can have the backend return the contents of any file it can read, including its environment, which holds the secret used to sign login sessions, the database address and the credentials of connected services. Another helper makes the backend process exit with a single request. Self-registration is open by default, so no existing account and no action by another user is needed. |
