CVE-2026-85451 Vulnerability Summary

CVE-2026-85451: MOOS core-moos through 10.4.0 contains a remote process termination vulnerability in the SuicidalSleeper component that uses a hard-coded passphrase for multicast command authorization. Any multicast-reachable peer can enumerate MOOS processes and send termination commands to trigger process shutdown by exploiting the default multicast group and port with the known passphrase.

Assessing the Risk of CVE-2026-85451

Access Complexity Graph

The exploitability of CVE-2026-85451 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-85451

With low attack complexity and no required privileges, CVE-2026-85451 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-85451, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2026-85451, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: Low
    CVE-2026-85451 could lead to minor leaks of non-critical information without major privacy breaches.
  • Integrity: None
    CVE-2026-85451 poses no threat to data integrity.
  • Availability: High
    CVE-2026-85451 can disrupt system operations, potentially causing complete denial of service (DoS).

CAPEC Common Attack Pattern Enumeration and Classification

  • Read Sensitive Constants Within an Executable CAPEC-191 An adversary engages in activities to discover any sensitive constants present within the compiled code of an executable. These constants may include literal ASCII strings within the file itself, or possibly strings hard-coded into particular routines that can be revealed by code refactoring methods including static and dynamic analysis.
  • Try Common or Default Usernames and Passwords CAPEC-70 An adversary may try certain common or default usernames and passwords to gain access into the system and perform unauthorized actions. An adversary may try an intelligent brute force using empty passwords, known vendor default credentials, as well as a dictionary of common usernames and passwords. Many vendor products come preconfigured with default (and thus well-known) usernames and passwords that should be deleted prior to usage in a production environment. It is a common mistake to forget to remove these default login credentials. Another problem is that users would pick very simple (common) passwords (e.g. "secret" or "password") that make it easier for the attacker to gain access to the system compared to using a brute force attack or even a dictionary attack using a full dictionary.
