CVE-2025-52914 Overview
CVE-2025-52914 is a SQL Injection vulnerability [CWE-89] in the Suite Applications Services component of Mitel MiCollab. The flaw stems from insufficient validation of user-supplied input. An authenticated attacker can submit crafted parameters to execute arbitrary SQL commands against the backend database.
Mitel disclosed the issue in security advisory MISA-2025-0008. Affected releases include MiCollab 10.0 through SP1 FP1 (10.0.1.101). Successful exploitation impacts the confidentiality, integrity, and availability of stored data.
Critical Impact
An authenticated attacker on the network can execute arbitrary SQL queries, enabling data theft, unauthorized record modification, and potential disruption of MiCollab unified communications services.
Affected Products
- Mitel MiCollab 10.0
- Mitel MiCollab 10.0 SP1
- Mitel MiCollab 10.0 SP1 FP1 (10.0.1.101)

Technical Details for CVE-2025-52914
Vulnerability Analysis
The vulnerability resides in the Suite Applications Services component of Mitel MiCollab. The component accepts user-controlled input and incorporates it into SQL statements without sufficient sanitization or parameterization. An attacker with valid low-privilege credentials can manipulate query logic to read, modify, or delete arbitrary database records.
MiCollab centralizes voice, video, messaging, and collaboration services for enterprise users. The database backing these services holds account data, call detail records, voicemail metadata, and configuration. SQL command execution against this store directly exposes sensitive communications metadata.
The issue maps to CWE-89: Improper Neutralization of Special Elements used in an SQL Command. EPSS data places the exploitation probability at 0.09%, though authenticated SQL injection on collaboration platforms remains a high-value target for lateral movement.
Root Cause
The root cause is missing or incomplete input validation before user input is concatenated into SQL queries. The Suite Applications Services code path does not enforce parameterized queries or strict allow-list validation on the affected parameters.
Attack Vector
Exploitation requires network reachability to the MiCollab Suite Applications Services interface and valid authentication. The attacker submits requests containing SQL metacharacters or stacked statements within vulnerable parameters. The backend database executes the injected payload with the privileges of the application service account.
No public proof-of-concept exploit is available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
See the Mitel Security Advisory MISA-2025-0008 for vendor technical details.
Detection Methods for CVE-2025-52914
Indicators of Compromise
- HTTP requests to MiCollab Suite Applications Services endpoints containing SQL metacharacters such as single quotes, UNION SELECT, --, ;, or OR 1=1 patterns.
- Database logs showing unexpected SELECT, INSERT, UPDATE, or DROP statements originating from the MiCollab application service account.
- Authentication events for low-privilege MiCollab accounts followed by anomalous query volume or sensitive table access.
- Outbound data transfers from the MiCollab server to unfamiliar destinations after authenticated user sessions.
Detection Strategies
- Deploy web application firewall rules that inspect MiCollab request parameters for SQL injection signatures.
- Enable database query auditing on the MiCollab backend and alert on statements outside the documented application baseline.
- Correlate authentication events with subsequent database activity to flag low-privilege accounts issuing administrative queries.
Monitoring Recommendations
- Forward MiCollab application, web server, and database logs to a centralized SIEM for correlation.
- Baseline normal Suite Applications Services request patterns and alert on parameter values containing SQL syntax.
- Monitor for privilege escalation attempts and unexpected schema discovery queries such as access to information_schema tables.
How to Mitigate CVE-2025-52914
Immediate Actions Required
- Apply the fixed MiCollab release identified in Mitel advisory MISA-2025-0008 as the primary remediation.
- Restrict network access to the MiCollab Suite Applications Services interface to trusted management networks and VPN segments.
- Audit and rotate credentials for all MiCollab user accounts, prioritizing accounts with access to the affected component.
- Review database and application logs for indicators of prior exploitation before patching.
Patch Information
Mitel has released fixed versions for MiCollab 10.0 through SP1 FP1. Refer to the Mitel Product Security Advisory MISA-2025-0008 and the Mitel Security Advisories portal for the current fixed build and upgrade guidance.
Workarounds
- Limit MiCollab portal exposure to internal networks using firewall ACLs until patching is complete.
- Enforce multi-factor authentication on all MiCollab accounts to reduce the risk of credential-based access.
- Apply least-privilege principles to the MiCollab database service account so injected queries cannot reach sensitive schemas.
- Increase logging verbosity on the Suite Applications Services component during the remediation window.
# Example: restrict MiCollab Suite Applications Services exposure with iptables
# Allow only the management subnet 10.10.5.0/24 to reach HTTPS
iptables -A INPUT -p tcp --dport 443 -s 10.10.5.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
