CVE-2026-85430
CriticalCVSS 9.1Summary
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.
Risk Assessment
Potential injection of false messages and denial of service, leading to data integrity and availability issues.
Recommendation
Update essential-moos to a patched version. Restrict UDP sources and implement datagram authentication.
Other vulnerabilities in MOOS essential-moos
See all- CVE-2026-85436High
MOOS essential-moos through 10.0.1 contains a buffer overflow vulnerability in CMOOSUDPLink::ReadPktFromArray() that allows remote attackers to corrupt heap memory by sending UDP datagrams with negative declared lengths. Attackers can send crafted UDP packets to the configured UDPListen port to trigger an oversized memcpy operation that writes past the destination buffer, causing heap corruption and denial of service.
- CVE-2026-85431High
MOOS essential-moos through version 10.0.1 contains an unauthenticated UDP packet injection vulnerability in pMOOSBridge when configured with UDPListen. Attackers can send crafted UDP packets to the configured port to inject arbitrary variables into the local MOOS community with spoofed source and community identifiers.
- CVE-2026-85427High
MOOS essential-moos pAntler through 10.0.1 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary programs by publishing a crafted MISSION_FILE message to the MOOSDB. Attackers can publish a mission file containing malicious Run entries that pAntler parses and executes via execvp() without authentication validation.
Original NVD description (English source)
MOOS essential-moos through 10.0.1 contains an authentication bypass vulnerability in pShare that accepts UDP datagrams from any source and republishes them with the attacker-claimed identity intact. Attackers can send crafted UDP datagrams to pShare input routes to inject messages into the local MOOS community under spoofed identities, or send malformed datagrams to crash the pShare process.
