CVE-2025-30023: Authenticated RCE Vulnerability Exploit

CVE-2025-30023 Overview

A critical vulnerability has been identified in the communication protocol used between Axis client and server components. The flaw allows an authenticated user to exploit insecure deserialization (CWE-502) to perform a remote code execution attack. This vulnerability affects the adjacent network attack surface, meaning attackers must have network proximity to the target system to exploit this vulnerability.

Critical Impact

Authenticated attackers on an adjacent network can achieve remote code execution with the potential for complete system compromise, including confidentiality, integrity, and availability impacts that can extend beyond the vulnerable component's security scope.

Affected Products

• Axis network devices with vulnerable communication protocols (refer to Axis Security Advisory for specific product versions)

Technical Details for CVE-2025-30023

Vulnerability Analysis

This vulnerability stems from insecure deserialization (CWE-502) in the communication protocol between Axis client and server components. Insecure deserialization occurs when untrusted data is used to abuse the logic of an application, inflict denial of service, or execute arbitrary code upon being deserialized. In this case, the protocol fails to properly validate serialized objects before processing them, allowing an authenticated attacker to inject malicious serialized payloads.

The vulnerability requires the attacker to be on an adjacent network and possess valid authentication credentials. Despite these prerequisites, the attack complexity remains low, and no user interaction is required for successful exploitation. The changed scope indicator suggests that successful exploitation can impact resources beyond the vulnerable component's security boundary.

Root Cause

The root cause of CVE-2025-30023 is improper handling of serialized data within the client-server communication protocol. The application deserializes data from the network without adequate validation of the object types or content, enabling an attacker to craft malicious serialized objects that execute arbitrary code upon deserialization.

Attack Vector

The attack requires an authenticated user with network adjacency to the target system. The attacker crafts a specially designed serialized payload containing malicious code and transmits it through the vulnerable communication protocol. When the target system deserializes this payload, the embedded code executes with the privileges of the application processing the request.

The insecure deserialization vulnerability manifests in the communication protocol's message handling routines. When malicious serialized data is processed, the deserialization logic instantiates attacker-controlled objects that can trigger arbitrary code execution. For complete technical details regarding the exploitation mechanism, refer to the Axis Security Advisory.

Detection Methods for CVE-2025-30023

Indicators of Compromise

• Unusual serialized data patterns in network traffic between Axis clients and servers
• Unexpected process spawning or command execution on Axis devices following protocol communication
• Anomalous authentication patterns from adjacent network segments
• Evidence of lateral movement originating from compromised Axis devices

Detection Strategies

• Monitor network traffic for malformed or suspicious serialized objects in the Axis communication protocol
• Implement network segmentation monitoring to detect unauthorized adjacent network access attempts
• Deploy endpoint detection and response (EDR) solutions to identify post-exploitation activities
• Analyze authentication logs for unusual patterns preceding suspicious device behavior

Monitoring Recommendations

• Enable verbose logging on Axis devices and forward logs to a centralized SIEM platform
• Implement network intrusion detection signatures for known deserialization attack patterns
• Monitor for unexpected outbound connections from Axis devices that may indicate successful exploitation
• Track and alert on privilege escalation attempts on systems within the adjacent network scope

How to Mitigate CVE-2025-30023

Immediate Actions Required

• Review the Axis Security Advisory for affected product versions and available patches
• Implement network segmentation to limit adjacent network access to Axis devices
• Audit and restrict user accounts with authentication privileges to the affected systems
• Monitor affected systems for indicators of compromise while awaiting patch deployment

Patch Information

Axis Communications has released a security advisory addressing CVE-2025-30023. Organizations should consult the Axis Security Advisory for specific patch information, affected firmware versions, and update instructions. Apply vendor-provided patches as soon as they become available for your specific product versions.

Workarounds

• Implement strict network segmentation to isolate Axis devices from untrusted network segments
• Restrict authentication access to only essential personnel with a legitimate business need
• Deploy network access control (NAC) solutions to prevent unauthorized devices from gaining adjacent network access
• Consider disabling non-essential client-server communication features until patches are applied

# Example network segmentation configuration for isolating Axis devices
# Consult your network administrator for environment-specific implementation

# Create a dedicated VLAN for Axis devices
# Restrict inter-VLAN routing to essential management traffic only
# Implement access control lists (ACLs) to limit adjacent network access
# Enable logging for all traffic to/from the isolated segment
