Title
Tonec Internet Download Manager Kernel Driver idmwfp.sys access control
Summary
A vulnerability was detected in Tonec Internet Download Manager up to 6.42 Build 63 on Windows. The impacted element is an unknown function of the file idmwfp.sys of the component Kernel Driver. The manipulation results in improper access controls. Attacking locally is a requirement. Internet Download Manager for Windows up to and including 6.42 Build 63 installs idmwfp.sys, a Windows kernel driver that exposes the \.\IDMWFP device interface to authenticated local users. The device object is created with an access control descriptor equivalent to D:P(A;;GA;;;AU), granting Authenticated Users generic access to the driver. The driver's IOCTL 0x12C028 handler accepts registry-operation subcommands 0x0C through 0x0F and processes caller-controlled registry paths and values. These handlers do not authenticate the caller, do not enforce the caller's registry permissions, and do not restrict operations to IDM-owned registry namespaces. A low-privileged local authenticated user can therefore read, create, modify, and delete arbitrary registry values under HKLM and HKU through the kernel driver. This includes registry configuration consumed by privileged Windows services and drivers and enables Local Privilege Escalation, high-privilege persistence, unauthorized system configuration disclosure or modification, and compromise of system confidentiality, integrity, and availability. Exploitation requires local access, low privileges, and no user interaction. A public proof of concept is available. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Title
Incorrect privilege assignment in Temporary Elevated Access Management (TEAM) for AWS IAM Identity Center
Summary
Incorrect privilege assignment in Temporary Elevated Access Management (TEAM) for AWS IAM Identity Center solution before version 1.5.1 might allow an authenticated remote user with application-level access to read, approve, modify, or revoke arbitrary access requests, thereby obtaining unintended temporary elevated access to the AWS accounts accessed using the TEAM deployment.
This issue has been addressed in TEAM version 1.5.1 or later. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.

Title
Import and export users and customers <= 2.4.17 - Authenticated (Subscriber+) Privilege Escalation via CSV Escape-Character Mismatch in Export/Import Round Trip via display_name and nickname Profile Fields
Summary
The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.4.17 via the plugin's own export and re-import workflow. The vulnerability exists because the exporter writes CSV cells using fputcsv() with a NUL byte (\0) as the escape character, while the importer parses the same file using SplFileObject::fgetcsv() with only a single delimiter argument, causing PHP's default backslash escape character to be applied instead; because the export column layout places display_name immediately before the role column and nickname immediately after, an attacker can store crafted values in those two profile fields — saved by WordPress core via the standard profile page — such that the escape mismatch causes the parser to merge the display_name cell into the role field and rebalance the column count via nickname, yielding administrator as the parsed role for their own row when it reaches the import_user function's add_role function. This makes it possible for authenticated attackers with Subscriber-level access or above to escalate their privileges to Administrator. Exploitation requires a site administrator to trigger the plugin's documented export re-import migration with both "Update existing users" and "Update roles for existing users" set to "yes".

Mitigation MIT-1
Architecture and Design
Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-17
Architecture and Design
Operation
Strategy: Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
