The Zephyr Project Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.3.202 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfilteredhtml has been disabled.

The Zephyr Project Manager plugin for WordPress is vulnerable to limited privilege escalation in all versions up to, and including, 3.3.101. This is due to the plugin not properly checking a users capabilities before allowing them to enable access to the plugin's settings through the updateuseraccess() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to grant themselves full access to the plugin's settings.

Potential buffer overflow vulnerabilities n the Zephyr Bluetooth subsystem.

Two potential signed to unsigned conversion errors and buffer overflow vulnerabilities at the following locations in the Zephyr IPM drivers.

The denial-of-service can be triggered by transmitting a carefully crafted CAN frame on the same CAN network as the vulnerable node. The frame must have a CAN ID matching an installed filter in the vulnerable node (this can easily be guessed based on CAN traffic analyses). The frame must contain the opposite RTR bit as what the filter installed in the vulnerable node contains (if the filter matches RTR frames, the frame must be a data frame or vice versa).

There is an error in the condition of the last if-statement in the function smpcheckkeys. It was rejecting current keys if all requirements were unmet.

usb device bluetooth class includes a buffer overflow related to implementation of netbufaddmem.

There is no check to see if slot 0 is being uploaded from the device to the host. When using encrypted images this means the unencrypted firmware can be retrieved easily.

A malicious / defective bluetooth controller can cause buffer overreads in the most functions that process HCI command responses.

Inconsistent handling of error cases in bluetooth hci may lead to a double free condition of a network buffer.

A malicious / defect bluetooth controller can cause a Denial of Service due to unchecked input in lereadbuffersizecomplete.

Zephyr OS IP packet handling does not properly drop IP packets arriving on an external interface with a source address equal to 127.0.01 or the destination address.

Lack of proper validation in HCI Host stack initialization can cause a crash of the bluetooth stack

The function dnscopyqname in dnspack.c performs performs a memcpy operation with an untrusted field and does not check if the source buffer is large enough to contain the copied data.

A malicious or malformed DNS packet without a payload can cause an out-of-bounds read, resulting in a crash (denial of service) or an incorrect computation.

A lack of input validation allows for out of bounds reads caused by malicious or malformed packets.

Potential buffer overflows in the Bluetooth subsystem due to asserts being disabled in /subsys/bluetooth/host/hcicore.c

Potential off-by-one buffer overflow vulnerability in the Zephyr fuse file system.

When the Global Pointer (GP) relative addressing is enabled (CONFIGRISCVGP=y), the gp reg points at 0x800 bytes past the start of the .sdata section which is then used by the linker to relax accesses to global symbols.

A malicious BLE device can send a specific order of packet sequence to cause a DoS attack on the victim BLE device

An malicious BLE device can crash BLE victim device by sending malformed gatt packet

Possible buffer overflow in ismountpoint

Signed to unsigned conversion esp32ipmsend

can: out of bounds in removerxfilter function

Unchecked length coming from user input in settings shell

At the most basic level, an invalid pointer can be input that crashes the device, but with more knowledge of the device’s memory layout, further exploitation is possible.

Potential buffer overflow vulnerability in the Zephyr CAN bus subsystem

Unchecked user input length in /subsys/net/l2/wifi/wifishell.c can cause buffer overflows.

The SJA1000 CAN controller driver backend automatically attempt to recover from a bus-off event when built with CONFIGCANAUTOBUSOFFRECOVERY=y. This results in calling ksleep() in IRQ context, causing a fatal exception.

Potential buffer overflow vulnerability at the following location in the Zephyr STM32 Crypto driver
