CVE-2026-42924
F5 · BIG-IP
An authenticated privilege escalation vulnerability exists in F5 BIG-IP via the iControl SOAP interface, allowing administrators to create unauthorized SNMP configuration objects.
Executive summary
A high-severity privilege escalation vulnerability in F5 BIG-IP allows authenticated users to perform unauthorized configuration changes, potentially leading to full system compromise.
Vulnerability
This vulnerability involves an improper authorization flaw within the iControl SOAP API. An attacker possessing Resource Administrator or Administrator privileges can manipulate SNMP configuration objects to escalate their operational control.
Business impact
The ability to escalate privileges within the BIG-IP management plane poses a significant risk to network infrastructure integrity. Successful exploitation could allow an attacker to gain unauthorized control over device monitoring and management, potentially facilitating data exfiltration or lateral movement. With a CVSS score of 8.7, this flaw represents a major security risk to critical infrastructure.
Remediation
Immediate Action: Identify and apply the vendor-supplied security patch or upgrade to the recommended version as detailed in the official F5 security advisory.
Proactive Monitoring: Audit iControl SOAP access logs for unusual SNMP configuration activity or unauthorized attempts to modify system-level settings.
Compensating Controls: Restrict access to the iControl SOAP interface to trusted management IP addresses and enforce strict Role-Based Access Control (RBAC) to limit the number of users with administrative privileges.
Exploitation status
Public Exploit Available: false
Analyst recommendation
Given the potential for administrative privilege escalation, organizations must prioritize the review of administrative accounts and apply necessary vendor patches immediately. Failure to remediate this vulnerability may allow malicious actors to compromise the management layer of critical network infrastructure.
