CVE-2026-85426

Pre-authentication heap overflow vulnerability in MOOS core-moos through 10.4.0 in MOOSCommPkt packet handling. Attackers can declare a negative packet length, leading to writing arbitrary data past a four-byte heap buffer during the HandShake phase.

Buffer overflow vulnerability in MOOS-IvP through 24.8.1 in StringToIvPFunction(), where dimension, piece, and degree counts from encoded BHV_IPF payloads are used without validation. Attackers can supply crafted payloads to write past the IvPBox weight array.

Multiple buffer overflow vulnerabilities in MOOS-IvP through 24.8.1 in IvP function string decoders that trust attacker-controlled length fields. Crafted encoded strings can overflow heap and stack buffers, potentially enabling remote code execution.

MOOS-IvP uFldNodeBroker through 24.8.1 fails to validate the source of TRY_SHORE_HOST messages, allowing any publisher to enroll attacker-controlled shore routes. Attackers can receive bridged vehicle traffic including sensor data and control information.

MOOS-IvP uFldShoreBroker through 24.8.1 fails to verify node ping authenticity before creating outbound bridge routes. Attackers can publish NODE_BROKER_PING messages with crafted HostRecord data to redirect bridged variables to attacker-controlled addresses.

MOOS essential-moos pShare through 10.0.1 fails to properly authorize PSHARE_CMD messages, allowing any publisher to reconfigure network routes and listeners at runtime. Attackers can send crafted messages to open new listeners and redirect or duplicate traffic.

MOOS essential-moos through 10.0.1 contains an authentication bypass in pShare that accepts UDP datagrams from any source and republishes them with attacker-claimed identity. Attackers can inject messages under spoofed identities or crash the pShare process.

MOOS core-moos through 10.4.0 contains an authentication bypass in the optional MOOSDB HTTP server, allowing unauthenticated clients to write variables. Attackers can modify MOOS variables including actuator and override commands without authentication.

MOOS-IvP iSay through 24.8.1 contains a remote code execution vulnerability in the SAY_MOOS variable handler that passes unsanitized text to a shell command. Attackers can publish messages with command substitution syntax to execute arbitrary commands as the iSay process user.

MOOS core-moos through 10.4.0 lacks authentication in the wire protocol, allowing unauthenticated clients to connect with full publish, subscribe, and database clear privileges. Attackers can bypass the compile-time protocol string check and connect with arbitrary client names to execute privileged operations including DB_CLEAR which resets all variables and clears client mail queues.
