CyberRota Analysis

AI-Generated

A buffer overflow vulnerability exists in the CMOOSSerialPort::GetTelegram() function of MOOS core-moos versions up to 10.4.0, allowing attackers with control over the serial line to exploit an off-by-one write that corrupts the stack. This could lead to potential code execution, making it critical for organizations using affected versions to prioritize patching. Users of this software, particularly those in environments where serial communication is utilized, should take immediate action to mitigate the risk.

Original NVD Description

MOOS core-moos through 10.4.0 contains a buffer overflow vulnerability in CMOOSSerialPort::GetTelegram() that writes a NUL terminator one byte past the serial telegram stack buffer. Attackers controlling the serial line can send a full-length telegram to trigger the off-by-one write, corrupting the stack and potentially enabling code execution.
