CVE-2024-47189 is a SQL injection vulnerability identified in the API interface of the AWV component of Mitel MiCollab, a unified communications platform widely used for audio, web, and video conferencing. The vulnerability exists due to improper sanitization of user-supplied input in API requests, which allows an unauthenticated attacker to inject malicious SQL commands. This flaw affects versions up to 9.8 SP1 FP2 (9.8.1.201). Exploiting this vulnerability does not require authentication or user interaction but does require the attacker to have knowledge of specific API details to craft effective injection payloads. Successful exploitation can lead to unauthorized reading of non-sensitive user provisioning information and execution of arbitrary SQL commands, potentially altering or deleting data and impacting database availability. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The CVSS v3.1 base score is 7.7, indicating high severity, with a network attack vector, high attack complexity, no privileges required, and no user interaction needed. Although no public exploits have been reported, the vulnerability poses a significant threat to the confidentiality, integrity, and availability of affected systems. Mitel has not yet published a patch or mitigation guidance at the time of this report, so organizations must monitor for updates and consider interim protective measures.

The impact of CVE-2024-47189 is substantial for organizations using vulnerable versions of Mitel MiCollab. An attacker exploiting this vulnerability can execute arbitrary SQL commands on the backend database, potentially leading to unauthorized disclosure of user provisioning data, which, while non-sensitive, could aid in further attacks or reconnaissance. More critically, the attacker can modify or delete data, compromising database integrity and availability, which could disrupt communication services reliant on MiCollab. Such disruption could affect business continuity, especially in organizations heavily dependent on unified communications for daily operations. The vulnerability's unauthenticated nature increases risk, as attackers do not need valid credentials to exploit it. This could facilitate automated attacks or exploitation by external threat actors. The absence of known exploits currently limits immediate widespread impact, but the vulnerability remains a significant risk until patched. Organizations in sectors such as finance, healthcare, government, and large enterprises using Mitel MiCollab are particularly vulnerable to operational disruption and potential data integrity issues.

1. Immediate monitoring for official patches or security advisories from Mitel is critical; apply any released updates promptly. 2. In the absence of patches, implement strict network segmentation and firewall rules to restrict access to the AWV API interface only to trusted internal networks and authorized personnel. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the AWV API endpoints. 4. Conduct thorough input validation and sanitization on all API inputs at the application layer if possible, or deploy proxy solutions that can enforce such controls. 5. Monitor logs and network traffic for unusual or suspicious API requests that may indicate exploitation attempts. 6. Limit database permissions for the MiCollab application to the minimum necessary to reduce the impact of potential SQL injection. 7. Educate IT and security teams about this vulnerability to ensure rapid detection and response. 8. Consider temporary disabling or restricting the AWV API interface if it is not essential to business operations until a patch is available.
