Executive brief
MOOS is a lightweight middleware messaging system used in robotics and autonomous systems. A buffer over-read vulnerability in the packet deserialization layer allows unauthenticated remote attackers to read sensitive memory by sending a malformed packet to the MOOSDB server port, potentially exposing credentials, encryption keys, or other sensitive data.
Technical details
The vulnerability is a buffer over-read in CMOOSCommPkt's deserialization logic that occurs when processing an abnormally short (four-byte) packet. The vulnerable component fails to validate packet length before attempting to read structured data from the buffer, resulting in out-of-bounds memory access. Attack vector is network-based via a direct TCP connection to the MOOSDB port; no authentication is required prior to exploitation. An attacker can read arbitrary memory contents from the affected process, disclosing sensitive information such as configuration data, credentials, or cryptographic material. Versions through 10.4.0 are affected.
