CVE-2026-93864 Vulnerability Summary

CVE-2026-93864: A link following vulnerability in WatchGuard Fireware OS’s firewall daemon allows a local attacker with code execution as a low-privileged system process to overwrite arbitrary files with root privileges, and to tamper with firewall IP set data, by planting a crafted file system object and triggering a list update. Written content is partially constrained.

Assessing the Risk of CVE-2026-93864

Access Complexity Graph

The exploitability of CVE-2026-93864 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-2026-93864

No exploitability data is available for CVE-2026-93864.

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-2026-93864, 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-2026-93864, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2026-93864 does not compromise confidentiality.
  • Integrity: None
    CVE-2026-93864 does not impact data integrity.
  • Availability: None
    CVE-2026-93864 does not affect system availability.

CAPEC Common Attack Pattern Enumeration and Classification

  • Explore for Predictable Temporary File Names CAPEC-149 An attacker explores a target to identify the names and locations of predictable temporary files for the purpose of launching further attacks against the target. This involves analyzing naming conventions and storage locations of the temporary files created by a target application. If an attacker can predict the names of temporary files they can use this information to mount other attacks, such as information gathering and symlink attacks.
  • Screen Temporary Files for Sensitive Information CAPEC-155 An adversary exploits the temporary, insecure storage of information by monitoring the content of files used to store temp data during an application's routine execution flow. Many applications use temporary files to accelerate processing or to provide records of state across multiple executions of the application. Sometimes, however, these temporary files may end up storing sensitive information. By screening an application's temporary files, an adversary might be able to discover such sensitive information. For example, web browsers often cache content to accelerate subsequent lookups. If the content contains sensitive information then the adversary could recover this from the web cache.
