CVE-2025-48539
SendPacketToPeer · SendPacketToPeer Multiple Products
**A high-severity vulnerability in the `acl_arbiter` component could allow an attacker to cause a denial of service or execute arbitrary code via malformed network packets.**.
Executive summary
A high-severity vulnerability in the acl_arbiter component could allow an attacker to cause a denial of service or execute arbitrary code via malformed network packets.
Vulnerability
An unspecified flaw exists in the SendPacketToPeer function within the acl_arbiter component. This suggests a vulnerability in packet processing, such as a buffer overflow or improper input validation, which could be triggered by a specially crafted network packet sent from a peer.
Business impact
A successful exploit could lead to a crash of the affected service, resulting in a denial-of-service condition that disrupts operations. Depending on the nature of the flaw, it could also allow for remote code execution, giving an attacker control over the affected system. The CVSS score of 8.0 (High) indicates a significant risk to system availability and integrity.
Remediation
Immediate Action: Apply the security updates provided by the vendor to patch the vulnerable acl_arbiter component.
Proactive Monitoring: Monitor network traffic for malformed or anomalous packets targeting the affected service. Check system logs for application crashes or errors related to packet processing.
Compensating Controls: If possible, configure firewalls or intrusion prevention systems (IPS) to block traffic from untrusted peers. Enforce strict access control lists (ACLs) to limit which systems can communicate with the vulnerable service.
Exploitation status
Public Exploit Available: false
Analyst recommendation
The potential for remote code execution or denial of service makes this a high-priority vulnerability. It is crucial for administrators to apply the vendor's patch immediately to prevent attackers from compromising or disrupting the availability of the affected service.
