CVE-2026-41217: CWE-732 Incorrect Permission Assignment for Critical Resource in F5 BIG-IP
A vulnerability exists in an undisclosed BIG-IP TMOS Shell (tmsh) command that may allow an authenticated attacker with resource administrator or administrator role to execute arbitrary system commands with higher privileges. In Appliance mode deployments, a successful exploit can allow the attacker to cross a security boundary. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-41217) in F5 BIG-IP TMOS Shell (tmsh) arises from incorrect permission assignment (CWE-732) that permits an authenticated attacker with elevated roles to execute arbitrary system commands with higher privileges. The issue affects versions 16.1.0, 17.1.0, 17.5.0, and 21.0.0. In Appliance mode, successful exploitation can allow crossing of security boundaries. The CVSS 3.1 base score is 6.0, reflecting medium severity with local attack vector, low attack complexity, high privileges required, no user interaction, unchanged scope, and high impact on confidentiality and integrity but no impact on availability. There is no vendor-provided patch or remediation level indicated, and no known exploits in the wild.
Potential Impact
An authenticated user with administrator or resource administrator privileges can leverage this vulnerability to execute arbitrary system commands with elevated privileges, potentially compromising system confidentiality and integrity. In Appliance mode deployments, this can lead to crossing security boundaries, increasing the risk of unauthorized access or control. Availability is not impacted. The vulnerability does not affect versions beyond those listed or versions that have reached End of Technical Support.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, organizations should monitor F5 advisories for updates. Until a patch is available, restrict administrator and resource administrator access to trusted personnel only and consider additional monitoring of privileged command executions to detect potential misuse.
