In the Linux kernel, the following vulnerability has been resolved: ip6_tunnel: clear skb2->cb[] in ip4ip6_err() Oskar Kjos reported the following problem. ip4ip6_err() calls icmp_send() on a cloned skb whose cb[] was written by the IPv6 receive path as struct inet6_skb_parm. icmp_send() passes IPCB(skb2) to __ip_options_echo(), which interprets that cb[] region as struct inet_skb_parm (IPv4). The layouts differ: inet6_skb_parm.nhoff at offset 14 overlaps inet_skb_parm.opt.rr, producing a non-zero rr value. __ip_options_echo() then reads optlen from attacker-controlled packet data at sptr[rr+1] and copies that many bytes into dopt->__data, a fixed 40-byte stack buffer (IP_OPTIONS_DATA_FIXED_SIZE). To fix this we clear skb2->cb[], as suggested by Oskar Kjos. Also add minimal IPv4 header validation (version == 4, ihl >= 5).

ChurchCRM is an open-source church management system. Prior to version 6.5.3, the allowRegistration, acceptKiosk, reloadKiosk, and identifyKiosk functions in the Kiosk Manager feature suffers from broken access control, allowing any authenticated user to allow and accept kiosk registrations, and perform other Kiosk Manager actions such as reload and identify. Version 6.5.3 fixes the issue.

Quadient DS-700 iQ devices through 2025-09-30 might have a race condition during the quick clicking of (in order) the Question Mark button, the Help Button, the About button, and the Help Button, leading to a transition out of kiosk mode into local administrative access. NOTE: the reporter indicates that the "behavior was observed sporadically" during "limited time on the client site," making it not "possible to gain more information about the specific kiosk mode crashing issue," and the only conclusion was "there appears to be some form of race condition." Accordingly, there can be doubt that a reproducible cybersecurity vulnerability was identified; sporadic software crashes can also be caused by a hardware fault on a single device (for example, transient RAM errors). The reporter also describes a variety of other issues, including initial access via USB because of the absence of a "lock-pick resistant locking solution for the External Controller PC cabinet," which is not a cybersecurity vulnerability (section 4.1.5 of the CNA Operational Rules). Finally, it is unclear whether the device or OS configuration was inappropriate, given that the risks are typically limited to insider threats within the mail operations room of a large company.

Missing Authorization vulnerability in oggix Ongkoskirim.id ongkoskirim-id allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Ongkoskirim.id: from n/a through <= 1.0.6.

A flaw has been found in SEAT Queue Ticket Kiosk up to 20250827. This affects an unknown part of the component Java RMI Registry Handler. This manipulation causes deserialization. The attack can only be done within the local network. The attack is considered to have high complexity. It is indicated that the exploitability is difficult. The vendor was contacted early about this disclosure but did not respond in any way.

@akoskm/create-mcp-server-stdio is an MCP server starter kit that uses the StdioServerTransport. Prior to version 0.0.13, the MCP Server is written in a way that is vulnerable to command injection vulnerability attacks as part of some of its MCP Server tool definition and implementation. The MCP Server exposes the tool `which-app-on-port` which relies on Node.js child process API `exec` which is an unsafe and vulnerable API if concatenated with untrusted user input. Version 0.0.13 contains a fix for the issue.

A vulnerability in Imprivata Enterprise Access Management (formerly Imprivata OneSign) allows bypassing the login screen of the shared kiosk workstation and allows unauthorized access to the underlying Windows system through the already logged-in autologon account due to insufficient handling of keyboard shortcuts. This issue affects Imprivata Enterprise Access Management versions 5.3 through 24.2.

Bluebird devices contain a pre-loaded kiosk application. This application exposes an unsecured service provider "com.bluebird.kiosk.launcher.IpartnerKioskRemoteService". A local attacker can bind to the AIDL-type service to modify device's global settings and wallpaper image. This issue affects all versions before 1.1.2.

RomM is a self-hosted rom manager and player. Versions prior to 3.10.3 and 4.0.0-beta.3 have an authenticated path traversal vulnerability in the `/api/raw` endpoint. Anyone running the latest version of RomM and has multiple users, even unprivileged users, such as the kiosk user in the official implementation, may be affected. This allows the leakage of passwords and users that may be stored on the system. Versions 3.10.3 and 4.0.0-beta.3 contain a patch.

The Secure Password extension in One Identity Password Manager before 5.14.4 allows local privilege escalation. The issue arises from a flawed security hardening mechanism within the kiosk browser used to display the Password Self-Service site to end users. Specifically, the application attempts to restrict privileged actions by overriding the native window.print() function. However, this protection can be bypassed by an attacker who accesses the Password Self-Service site from the lock screen and navigates to an attacker-controlled webpage via the Help function. By hosting a crafted web page with JavaScript, the attacker can restore and invoke the window.print() function, launching a SYSTEM-privileged print dialog. From this dialog, the attacker can exploit standard Windows functionality - such as the Print to PDF or Add Printer wizard - to spawn a command prompt with SYSTEM privileges. Successful exploitation allows a local attacker (with access to a locked workstation) to gain SYSTEM-level privileges, granting full control over the affected device.
