CVE-2025-52914 is a high-severity SQL Injection vulnerability affecting the Suite Applications Services component of Mitel MiCollab versions 10.0 through SP1 FP1 (specifically version 10.0.1.101). This vulnerability arises due to insufficient validation of user-supplied input, allowing an authenticated attacker to inject arbitrary SQL commands into the backend database. Exploiting this flaw could enable the attacker to execute unauthorized SQL queries, potentially leading to unauthorized data access, data modification, or deletion, as well as disruption of service. The vulnerability requires the attacker to have valid authentication credentials, but does not require any user interaction beyond that. The CVSS v3.1 base score is 8.8, reflecting a high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and no user interaction needed. The vulnerability is classified under CWE-89, which corresponds to SQL Injection issues. No known exploits are currently reported in the wild, and no official patches or mitigations have been linked yet. Given the nature of Mitel MiCollab as a unified communications platform widely used in enterprise telephony and collaboration, exploitation could severely impact business communications and sensitive data confidentiality.

For European organizations, this vulnerability poses a significant risk due to the widespread use of Mitel MiCollab in enterprise environments, including government, healthcare, finance, and large corporations. Successful exploitation could lead to unauthorized access to sensitive communications data, disruption of critical collaboration services, and potential data breaches involving personal and corporate information. This could result in regulatory non-compliance under GDPR, financial losses, reputational damage, and operational downtime. The requirement for authentication limits exposure to some extent, but insider threats or compromised credentials could be leveraged by attackers. The high impact on confidentiality, integrity, and availability means that organizations relying on MiCollab for daily operations could face severe consequences if this vulnerability is exploited.

Organizations should prioritize the following mitigation steps: 1) Immediately verify if their Mitel MiCollab deployments are running affected versions (10.0 through SP1 FP1, specifically 10.0.1.101). 2) Monitor Mitel’s official security advisories for patches or updates addressing CVE-2025-52914 and apply them promptly once available. 3) Implement strict access controls and multi-factor authentication to reduce the risk of credential compromise, as exploitation requires authenticated access. 4) Conduct thorough input validation and sanitization on any custom integrations or extensions interacting with the Suite Applications Services component. 5) Employ database activity monitoring and anomaly detection to identify suspicious SQL queries indicative of injection attempts. 6) Regularly audit user accounts and permissions to minimize the attack surface. 7) Consider network segmentation to isolate critical communication infrastructure and limit lateral movement in case of compromise. 8) Educate administrators and users about phishing and credential security to prevent initial access by attackers.
