CVE-2026-21765: CWE-732 Incorrect Permission Assignment for Critical Resource in HCLSoftware BigFix Platform
CVE-2026-21765 is a vulnerability in HCL BigFix Platform versions 11. 0. 0 through 11. 0. 5 where private cryptographic keys on Windows hosts have overly permissive file system permissions. This incorrect permission assignment could allow unauthorized users with local access to read or modify these critical keys. The vulnerability has a high severity with a CVSS score of 8. 8, indicating a significant impact on confidentiality, integrity, and availability. No patch or official remediation guidance is currently provided by the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
HCL BigFix Platform versions 11.0.0 to 11.0.5 suffer from CWE-732 (Incorrect Permission Assignment for Critical Resource) and CWE-276 (Incorrect Default Permissions) due to insecure file system permissions on private cryptographic keys stored on Windows hosts. These overly permissive permissions could allow local users with low privileges to access or manipulate sensitive cryptographic material, potentially compromising the security of the platform. The vulnerability is rated high severity with a CVSS 3.1 score of 8.8, reflecting low attack complexity but requiring local privileges and no user interaction. The vulnerability is published but no patch or official fix information is currently available.
Potential Impact
If exploited, this vulnerability could lead to unauthorized disclosure or modification of private cryptographic keys on affected Windows hosts, severely impacting confidentiality, integrity, and availability of the HCL BigFix Platform. This could enable privilege escalation or compromise of secure communications relying on these keys. However, exploitation requires local access with low privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to affected Windows hosts to trusted administrators only and audit file system permissions on private cryptographic keys to ensure they are not overly permissive.
