Command Injection Vulnerability in F5 Networks BIG-IP Product

CVE-2025-20029

What is CVE-2025-20029?

CVE-2025-20029 is a serious command injection vulnerability found in F5 Networks' BIG-IP product, specifically affecting the iControl REST API and the BIG-IP TMOS Shell (tmsh). This vulnerability enables an authenticated attacker to execute arbitrary system commands on affected devices. Given that BIG-IP serves critical roles in managing application delivery and security for many organizations, the potential for exploitation could lead to significant operational disruptions and compromise of sensitive data.

Technical Details

The vulnerability stems from improper handling of input within the save command of the iControl REST and tmsh. By leveraging this weakness, an attacker with valid credentials could construct malicious input to execute unauthorized commands on the underlying operating system. This escalates the risk of gaining deeper access to the system, manipulating configurations, or causing disruption to service stability.

Potential Impact of CVE-2025-20029

1. Unauthorized System Access: Exploiting this vulnerability could enable attackers to gain unauthorized access to critical system functions, allowing them to alter configurations or extract sensitive information.

2. Service Disruption: The ability to execute arbitrary commands may lead to system instability or downtime, impacting organizational operations and availability of services relying on the BIG-IP product.

3. Data Breaches: Should an attacker successfully exploit this vulnerability, they may obtain access to sensitive organizational data and potentially launch further attacks within the internal network.
