BullWall Ransomware Containment supports configurable file and directory exclusions such as '$RECYCLE.BIN' to balance monitoring scope and performance. Certain exclusion patterns could allow an authenticated attacker to rename directories in a way that avoids monitoring. Fixed in 4.6.1.14 and 5.0.0.42, which remove hardcoded exclusion behavior and exposes exclusion handling as configurable settings.Show less

The Dyson MQTT server (2022 and possibly later) allows publications and subscriptions by a client that has the correct values of AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, and device serial number, even if a device (such as a Pure Hot+Cool device) has been removed and is not visible in the supported MyDyson app. This could allow an unexpected actor to obtain control and set the room temperature (up to 37 Celsius) if ownership of the device is transferred without wiping the device. NOTE: the Supplier's position is that this is a potential vulnerability that dates back 4 years ago in 2022 and "we are unable to replicate that anymore." Based on the submitted report, in order to leverage this issue, an attacker needs to own a Dyson device with full privileges, sniff for the AWS credentials, and then transfer ownership of that Dyson device to the victim. Even if these steps were successfully accomplished, the attacker only acquires the ability to configure the Dyson device within its safe operating range, and does not acquire the ability to execute code on the device or obtain sensitive information.Show less

Framelink Figma MCP Server before 0.6.3 allows an unauthenticated remote attacker to execute arbitrary operating system commands via a crafted HTTP POST request with shell metacharacters in input that is used by a fetchWithRetry curl command. The vulnerable endpoint fails to properly sanitize user-supplied input, enabling the attacker to inject malicious commands that are executed with the privileges of the MCP process. Exploitation requires network access to the MCP interface.Show less

An internal product security audit of Lenovo XClarity Orchestrator (LXCO) discovered the below vulnerability: An attacker with access to a device on the local Lenovo XClarity Orchestrator (LXCO) network segment may be able to manipulate the local device to create an alternate communication channel which could allow the attacker, under certain conditions, to directly interact with backend LXCO API services typically inaccessible to users. While access controls may limit the scope of interaction, this could result in unauthorized access to internal functionality or data. This issue is not exploitable from remote networks.Show less

The Microsoft vulnerable driver block list is implemented as Windows Defender Application Control (WDAC) policy. Entries that specify only the to-be-signed (TBS) part of the code signer certificate are properly blocked, but entries that specify the signing certificate's TBS hash along with a 'FileAttribRef' qualifier (such as file name or version) may not be blocked, whether hypervisor-protected code integrity (HVCI) is enabled or not. NOTE: The vendor disputes this CVE ID assignment and states that the driver blocklist is intended for use with HVCI.Show less
