CVE-2025-27262 is a high-severity command injection vulnerability identified in the Ericsson Indoor Connect 8855 device. This vulnerability stems from improper neutralization of special elements used in operating system commands (CWE-78), allowing an attacker to inject and execute arbitrary OS commands. The flaw can be exploited locally by an attacker with limited privileges (PR:L) without requiring user interaction (UI:N). The vulnerability affects the integrity and confidentiality of the system by enabling unauthorized disclosure and modification of user and configuration data. Additionally, it may allow execution of commands with escalated privileges, potentially leading to modification of system files and configurations, and impacting service availability. The CVSS 4.0 base score of 8.5 reflects the significant impact on confidentiality, integrity, and availability, with a low attack vector (local), low attack complexity, and no privileges required beyond limited local access. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in February 2025 and published in September 2025, indicating recent discovery and disclosure. The Ericsson Indoor Connect 8855 is a device used primarily for indoor wireless connectivity, often deployed in enterprise and industrial environments to enhance cellular coverage. The vulnerability's exploitation could allow attackers to compromise the device, manipulate network traffic, and disrupt communications within affected organizations.

For European organizations, the exploitation of CVE-2025-27262 could have severe consequences. The Ericsson Indoor Connect 8855 is likely deployed in critical infrastructure, corporate campuses, and industrial settings to ensure reliable indoor cellular connectivity. A successful attack could lead to unauthorized access to sensitive configuration and user data, undermining confidentiality and potentially exposing private communications. Integrity loss could result in malicious reconfiguration of network parameters, enabling persistent attacks or data interception. Availability impacts could disrupt cellular coverage indoors, affecting business operations, emergency communications, and IoT device connectivity. Given the device's role in network infrastructure, exploitation could cascade to broader network disruptions. European organizations relying on Ericsson's indoor connectivity solutions must consider the risk of targeted attacks, especially in sectors such as telecommunications, manufacturing, healthcare, and government, where network reliability and data security are paramount.

To mitigate this vulnerability, European organizations should: 1) Immediately inventory and identify all Ericsson Indoor Connect 8855 devices within their networks. 2) Monitor vendor communications closely for official patches or firmware updates addressing CVE-2025-27262 and apply them promptly upon release. 3) Restrict local access to these devices to trusted personnel only, employing strict access controls and network segmentation to limit exposure. 4) Implement enhanced logging and monitoring on these devices to detect unusual command executions or configuration changes indicative of exploitation attempts. 5) Where possible, disable or restrict any unnecessary local management interfaces or services that could be leveraged for command injection. 6) Conduct regular security assessments and penetration tests focusing on these devices to identify potential exploitation vectors. 7) Educate IT and security staff about the vulnerability and signs of compromise to ensure rapid detection and response. 8) Consider deploying network-level protections such as intrusion detection/prevention systems tuned to detect anomalous traffic patterns related to these devices.
