Buffer Over-Read in MOOS-IvP Due to Whitespace Handling

Executive Summary

This vulnerability is a buffer over-read in MOOS-IvP versions up to 24.8.1. It occurs in functions that strip whitespace from strings but incorrectly calculate buffer indices using the original string length. Attackers can exploit this by sending specially crafted NODE_REPORT messages with leading or trailing whitespace to read beyond allocated memory and access adjacent data.

Detection Guidance

This vulnerability involves buffer over-reads in MOOS-IvP's string handling functions. Detection requires inspecting network traffic for NODE_REPORT messages with unusual whitespace patterns or analyzing the MOOS-IvP application logs for memory access violations. No specific commands are provided in the available context.

Impact Analysis

This vulnerability could allow attackers to read sensitive memory contents, potentially exposing confidential data or system information. It may lead to information disclosure, crashes, or unexpected behavior in affected applications using MOOS-IvP. Systems processing untrusted NODE_REPORT messages are particularly at risk.

Compliance Impact

This vulnerability allows attackers to read adjacent memory via crafted NODE_REPORT messages, which could potentially expose sensitive data. This may impact compliance with GDPR (data protection) and HIPAA (health information privacy) if such data is involved.

Useful 0 Not Useful 0

Mitigation Strategies

Immediate mitigation steps include updating MOOS-IvP to version 24.8.1 or later, monitoring network traffic for suspicious NODE_REPORT messages, and applying input validation to strip or sanitize whitespace in received messages. The vulnerability allows memory access beyond buffer bounds, so patching is critical.
