CVE-2025-55322 is a vulnerability identified in Microsoft OmniParser version 1.0.0, categorized under CWE-1327, which involves binding a network service to an unrestricted IP address. This misconfiguration allows the OmniParser service to listen on all network interfaces, including public-facing ones, without proper access controls. Consequently, an unauthenticated attacker can remotely connect to the service and execute arbitrary code over the network, potentially compromising the host system. The vulnerability does not require any user interaction or prior authentication, increasing its exploitability. The CVSS v3.1 base score of 7.3 reflects the network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N), with impacts on confidentiality, integrity, and availability rated as low to moderate (C:L/I:L/A:L). Although no exploits have been reported in the wild, the absence of patches and the critical nature of remote code execution vulnerabilities necessitate immediate attention. The root cause is the software's failure to restrict binding to specific, trusted IP addresses or interfaces, exposing the service to potentially hostile networks. This vulnerability could be leveraged to gain unauthorized access, execute malicious payloads, and disrupt services running on affected systems.

The impact of CVE-2025-55322 is significant for organizations deploying Microsoft OmniParser 1.0.0, especially those exposing the service to untrusted networks such as the internet or large internal networks without segmentation. Successful exploitation can lead to unauthorized remote code execution, allowing attackers to compromise system confidentiality by accessing sensitive data, integrity by modifying or injecting malicious code, and availability by disrupting or crashing the service. This can result in data breaches, lateral movement within networks, and potential full system compromise. Enterprises relying on OmniParser for critical data parsing or processing tasks may face operational disruptions and reputational damage. The lack of authentication and user interaction requirements lowers the barrier for exploitation, increasing the risk of automated attacks or wormable scenarios if combined with other vulnerabilities. While no known exploits exist yet, the vulnerability's characteristics make it a prime target for attackers once exploit code becomes available.

To mitigate CVE-2025-55322, organizations should immediately restrict network exposure of OmniParser services by configuring firewalls and network access controls to limit inbound connections only to trusted IP addresses and internal networks. Disable or block OmniParser instances from binding to all interfaces; if possible, configure the software to bind only to specific, trusted IP addresses or localhost. Employ network segmentation to isolate vulnerable systems from critical infrastructure and sensitive data stores. Monitor network traffic for unusual connections to OmniParser ports and implement intrusion detection/prevention systems with signatures targeting anomalous OmniParser activity. Maintain strict patch management and subscribe to Microsoft security advisories to apply updates promptly once patches are released. Consider deploying application-layer gateways or reverse proxies that enforce authentication and access control in front of OmniParser services. Conduct regular vulnerability scans and penetration tests to identify exposure. Finally, develop incident response plans specific to OmniParser compromise scenarios to reduce response time in case of exploitation.
