Impact

Successful exploitation results in a denial-of-service condition for the pMarineViewer operator display. In the context of marine robotic missions, this prevents operators from receiving real-time situational awareness, potentially leading to the loss of control or monitoring of autonomous assets. The vulnerability is unauthenticated and impacts the core visualization utility of the MOOS-IvP software suite.

Recommendation

Prioritized actions for security teams:

• Inventory systems running MOOS-IvP and identify instances of pMarineViewer version 24.8.1 or earlier.
• Implement network-level or middleware access controls to restrict access to the MOOS publish/subscribe communication bus, preventing unauthorized entities from injecting arbitrary NODE_REPORT messages.
• Prioritize the deployment of updates provided by the MOOS-IvP maintainers that implement validation and limiting logic on node identity tracking.

An attacker with network access to the MOOS community can send a malformed or malicious REALMCAST_REQ message containing an unbounded duration or an excessively large variable list. By registering these long-lived pipeways, the attacker forces pRealm to process and generate output indefinitely. This unchecked resource consumption can lead to severe performance degradation or total service unavailability for the pRealm process, impacting the stability and operation of the MOOS-IvP environment. This vulnerability affects all versions up to and including 24.8.1.

Impact

Successful exploitation leads to a denial-of-service condition for the pRealm component. In the context of autonomous marine vehicles, this can compromise the ability of the system to process real-time environmental data or command-and-control telemetry, potentially causing critical system instability or operational failure.

Recommendation

Prioritized actions for security and engineering teams:

• Update MOOS-IvP to the latest version that contains a patch for CVE-2026-85447.
• Implement network-level segmentation to restrict access to the MOOS community communications, ensuring only trusted systems can submit subscription requests to pRealm.
• Monitor system-level resource usage for the pRealm process, specifically looking for sustained high CPU and memory utilization that aligns with periods of unusual network traffic.

This flaw allows an attacker capable of communicating with the uFldNodeComms component to craft malicious NODE_MESSAGE packets. By populating the source identity field in the message payload with the name of a legitimate, trusted node, an attacker can impersonate that node. This allows for the injection of arbitrary variable notifications into the MOOS database, enabling unauthorized control, data corruption, or manipulation of the autonomy behaviors controlled by the MOOS-IvP system.

Impact

Successful exploitation allows for the injection of unauthorized command or state information into the system's database. Given the nature of MOOS-IvP in robotic and autonomous system control, this can result in the subversion of mission-critical behaviors, leading to loss of control, erratic navigation, or data manipulation.

Recommendation

1. Upgrade all instances of MOOS-IvP to a patched version beyond 24.8.1 once available to address the flawed identity validation logic.
2. Implement network-level segmentation to restrict access to the uFldNodeComms communication port to only known and trusted peer addresses, mitigating the impact of the identity spoofing vulnerability.
3. Inspect firewall logs or network monitoring tools for unauthorized traffic attempting to reach the port utilized by uFldNodeComms from unexpected source IPs.

Attack Chain

1. Attacker establishes a TCP/IP connection to the target host on the MOOS communication port.
2. Attacker initiates the HandShake phase of the communication protocol.
3. Attacker crafts a malicious packet header containing a negative integer in the packet length field.
4. The victim application receives the malicious packet via the InflateTo() function.
5. The vulnerability in the signed integer check allows the negative length to pass validation.
6. The application performs a heap-based memory allocation based on the unchecked length.
7. The recv() function processes the attacker-supplied data, resulting in a heap overflow of the internal four-byte buffer.
8. Attacker achieves arbitrary memory write, leading to remote code execution or process termination.

Impact

Successful exploitation of this vulnerability allows unauthenticated remote attackers to execute arbitrary code or cause a denial-of-service condition on affected MOOS installations. This affects systems utilizing MOOS core-moos versions 10.4.0 and earlier. Organizations relying on this software for underwater vehicle communication or similar robotics research environments are at high risk if instances are exposed to untrusted networks.

Recommendation

Prioritized, concrete actions:

• Patch core-moos by upgrading to a version exceeding 10.4.0 immediately upon release of vendor updates.
• Until patching is possible, restrict access to MOOS communication ports via host-based firewalls or network access control lists to known trusted endpoints only.
• Monitor network traffic for anomalous packet headers directed toward MOOS services, specifically looking for TCP streams containing negative length identifiers in the handshake phase.

Impact

Successful exploitation of these vulnerabilities allows an attacker to execute arbitrary code with the privileges of the MOOS-IvP process. In many deployments, these processes operate within critical autonomous systems or research environments. If exploited, an attacker could gain persistent access, exfiltrate sensitive mission data, or disrupt the operation of underwater autonomous vehicles and other marine robotic systems using the MOOS-IvP framework.

Recommendation

• Upgrade all instances of MOOS-IvP to version 24.8.2 or later to address the vulnerable IvP function string decoders identified in CVE-2026-85437.
• Audit all external inputs feeding into MOOS variables and restrict access to alog files to trusted administrative users only.
• Monitor process integrity for abnormal crashes or memory access violations that might indicate attempted exploitation of these buffer overflows.

Impact

Successful exploitation allows for the redirection of sensitive telemetry and control variables to malicious infrastructure. In maritime autonomous systems, this can lead to operational disruption, loss of communication with remote vessels, or the injection of false navigational or control data, potentially causing physical damage or loss of autonomous assets.

Recommendation

• Upgrade uFldShoreBroker to a patched version beyond 24.8.1 immediately upon vendor availability.
• Implement strict network segmentation for systems running MOOS-IvP to limit the exposure of the messaging bus to unauthorized participants.
• Audit and restrict permissions for publishing 'NODE_BROKER_PING' messages to known, authenticated, and trusted sources within the MOOS-IvP network.
• Monitor network traffic for unexpected outbound connections from nodes running uFldShoreBroker to unknown or non-standard external destinations.

Impact

Successful exploitation allows attackers to perform unauthorized message injection, potentially leading to the corruption of operational data or the execution of unauthorized commands within the MOOS community. Denial-of-service attacks against pShare can disrupt communication between critical mission components, rendering autonomous systems inoperable or uncontrollable.

Recommendation

• Monitor network traffic for unexpected UDP communication directed at the port used by the pShare process.
• Implement network-level access control lists (ACLs) to restrict access to the pShare UDP port to trusted IP addresses only.
• Update all instances of MOOS-IvP essential-moos to a version that implements input validation and authentication for incoming UDP datagrams, if available.
• Audit logs for repeated service restarts or process crashes of the pShare binary, which may indicate attempted exploitation of the denial-of-service vulnerability.

Impact

Successful exploitation allows for full command execution on the host running the uMemWatch process. Given the role of MOOS-IvP in autonomous vehicle systems, this could lead to unauthorized control of system resources, manipulation of sensor data, or total system compromise, resulting in mission failure or physical equipment hazards.

Recommendation

• Patch CVE-2026-85426 by upgrading the MOOS-IvP suite to a version greater than 24.8.1 immediately.
• Audit process execution logs for instances where uMemWatch spawns unexpected shells or system utilities (e.g., sh, bash, python).
• Enforce principle of least privilege by running the uMemWatch process with a dedicated, non-privileged service account.

An attacker capable of publishing messages to the MOOS community database (DB) can manipulate the SAY_MOOS variable to include shell command substitution characters, such as backticks or "$( )" syntax. When the iSay process parses these malformed messages, the shell interprets the injected sequences as commands, leading to arbitrary code execution under the privileges of the iSay process. This vulnerability is particularly relevant in autonomous vehicle and robotic systems where MOOS-IvP is deployed to facilitate inter-process communication and task coordination.

Attack Chain

1. Attacker gains network access to the MOOS community database (MOOSDB) via the configured MOOS port.
2. Attacker crafts a malicious MOOS message containing shell command injection syntax (e.g., SAY_MOOS = "test \whoami`"`).
3. Attacker publishes the crafted message to the MOOSDB using standard MOOS communication protocols.
4. The iSay process, subscribed to updates on the SAY_MOOS variable, receives the malicious payload.
5. The iSay process passes the payload string to a system execution function (e.g., popen or system) without sanitization.
6. The underlying system shell executes the attacker's injected command.
7. Attacker achieves remote code execution with the permissions of the iSay application.

Impact

Successful exploitation allows an attacker to execute arbitrary code on the host running the iSay process. Given that MOOS-IvP is frequently utilized in unmanned robotic and autonomous surface vehicles, this could lead to full system compromise, exfiltration of telemetry data, or disruption of mission-critical control software.

Recommendation

• Patch the MOOS-IvP environment by updating to a version beyond 24.8.1 once the vendor provides a remediation.
• Implement strict input validation within the MOOSDB gateway to restrict the characters allowed in the SAY_MOOS variable.
• Monitor the iSay process for anomalous child process spawning, such as /bin/sh or /bin/bash executions that originate from the iSay binary.
• Segment the network to ensure that only authorized nodes can publish to the MOOSDB.
