Title

F5 BIG-IP iHealth工具权限绕过漏洞

Description

F5 BIG-IP是F5公司的一款集成了网络流量编排、负载均衡、智能DNS，远程接入策略管理等功能的应用交付平台。 BIG-IP的iHealth工具（TMOS Shell的某个模块）存在权限绕过漏洞，该漏洞产生的原因是iHealth工具未正确限制具有资源管理员角色的认证用户，导致其可以绕过tmsh限制并获得Advanced Shell（bash）访问权限。攻击者可利用该漏洞绕过Appliance模式下的安全边界，获取更高权限，造成系统安全风险。

Vulnerability from cvelistv5 – Published: 2025-10-15 13:55 – Updated: 2026-02-26 16:57

Title

BIG-IP TMSH vulnerability

Summary

A vulnerability exists in the iHealth command that may allow an authenticated attacker with at least a resource administrator role to bypass tmsh restrictions and gain access to a bash shell. For BIG-IP systems running in Appliance mode, 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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
