CVE-2025-61880 Overview
CVE-2025-61880 is an insecure deserialization vulnerability affecting Infoblox NIOS through version 9.0.7. This vulnerability allows remote attackers to achieve code execution by exploiting improper handling of serialized data. Infoblox NIOS is a widely deployed network infrastructure management platform used for DNS, DHCP, and IP address management (DDI) services in enterprise environments.
Critical Impact
Successful exploitation of this insecure deserialization flaw can result in remote code execution, potentially allowing attackers to gain full control of affected Infoblox NIOS appliances and compromise critical network infrastructure.
Affected Products

Technical Details for CVE-2025-61880
Vulnerability Analysis
This vulnerability is classified as CWE-502 (Deserialization of Untrusted Data). Insecure deserialization occurs when an application deserializes data from untrusted sources without proper validation or sanitization. In the context of Infoblox NIOS, the vulnerability allows attackers with low-privilege network access to send maliciously crafted serialized objects to the appliance.
When the NIOS platform processes these malicious serialized payloads, it can instantiate arbitrary objects and execute attacker-controlled code. This type of vulnerability is particularly dangerous in network infrastructure components like Infoblox NIOS because successful exploitation provides attackers with a foothold in critical DNS and DHCP infrastructure.
Root Cause
The root cause of CVE-2025-61880 lies in the insufficient validation of serialized data before deserialization. The affected NIOS versions fail to properly verify the integrity and trustworthiness of incoming serialized objects, allowing attackers to inject malicious object chains (commonly known as gadget chains) that execute arbitrary code when processed by the application.
Attack Vector
The attack is network-based and requires low privileges to execute, with no user interaction necessary. An attacker can exploit this vulnerability by:
- Identifying an exposed Infoblox NIOS appliance on the network
- Crafting a malicious serialized payload containing code execution gadget chains
- Sending the payload to the vulnerable deserialization endpoint
- The NIOS appliance deserializes the payload, triggering arbitrary code execution
Technical details and security patches are available in the Infoblox Security Advisory for CVE-2025-61879 and CVE-2025-61880.
Detection Methods for CVE-2025-61880
Indicators of Compromise
- Unusual network traffic patterns to Infoblox NIOS management interfaces
- Unexpected process spawning or command execution on NIOS appliances
- Anomalous serialized data in network traffic to NIOS endpoints
- Suspicious log entries indicating deserialization errors or exceptions
Detection Strategies
- Monitor network traffic for unusually large or malformed serialized payloads targeting NIOS appliances
- Implement application-layer inspection for known deserialization attack patterns
- Deploy endpoint detection and response (EDR) solutions capable of detecting post-exploitation activity on network appliances
- Review Infoblox NIOS logs for authentication anomalies and unexpected administrative actions
Monitoring Recommendations
- Enable comprehensive logging on all Infoblox NIOS appliances
- Configure SIEM alerts for suspicious activity patterns associated with deserialization attacks
- Monitor for unauthorized configuration changes to DNS and DHCP services
- Implement network segmentation monitoring to detect lateral movement from compromised appliances
How to Mitigate CVE-2025-61880
Immediate Actions Required
- Review the Infoblox Security Advisory for specific patch information and upgrade guidance
- Restrict network access to Infoblox NIOS management interfaces to trusted administrative networks only
- Implement network segmentation to isolate NIOS appliances from untrusted network segments
- Audit current NIOS deployments to identify all instances running vulnerable versions through 9.0.7
Patch Information
Infoblox has published a security advisory addressing this vulnerability. Organizations should consult the Infoblox Security Advisory for CVE-2025-61879 and CVE-2025-61880 for specific patch versions and upgrade instructions. It is strongly recommended to upgrade affected NIOS installations to a patched version as soon as possible.
Workarounds
- Implement strict network access controls to limit exposure of NIOS management interfaces
- Deploy web application firewalls (WAF) or intrusion prevention systems (IPS) with deserialization attack detection capabilities
- Enable additional authentication mechanisms for NIOS administrative access
- Consider temporarily isolating vulnerable appliances until patches can be applied
# Network access restriction example (firewall rules)
# Restrict NIOS management interface access to trusted admin networks only
# Consult your firewall documentation for specific syntax
# Example: Allow only trusted admin subnet to access NIOS management
# iptables -A INPUT -s 10.0.0.0/24 -d <NIOS_IP> -p tcp --dport 443 -j ACCEPT
# iptables -A INPUT -d <NIOS_IP> -p tcp --dport 443 -j DROP
