Mitel MiCollab Path Traversal (CVE-2024-41713)

Historical catalog analysis: CISA added this entry on January 07, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2024-41713 is a path traversal vulnerability (CWE-22) affecting Mitel MiCollab. This flaw allows an unauthenticated attacker to gain unauthorized access to the system. According to source data, this vulnerability can be chained with CVE-2024-55550, which enables a remote, unauthenticated attacker to read arbitrary files from the server.

Exposure and applicability

This vulnerability applies to organizations deploying Mitel MiCollab infrastructure. The risk is elevated because the flaw is reported as having known use in ransomware campaigns. Because the entry path does not require authentication, any exposed MiCollab instance may be susceptible to initial unauthorized access and subsequent file exfiltration if chained with CVE-2024-55550.

Remediation priorities

Based on the reported exploitation status, vulnerability management teams should prioritize the following actions:

1. Immediate Mitigation Deployment: Apply vendor-provided mitigations as specified in the official security advisory. If mitigations are unavailable for a specific deployment, the source suggests discontinuing use of the product.
2. Chain Analysis: Specifically identify and address CVE-2024-55550 alongside CVE-2024-41713 to prevent the escalation from unauthorized access to arbitrary file reads.
3. Exposure Reduction: Evaluate whether the MiCollab interface is unnecessarily exposed to the public internet, as this increases the likelihood of unauthenticated remote exploitation.

How to validate remediation

To ensure that exposure has been reduced, defenders should move beyond simple version checks:

• Configuration Audit: Verify that the specific mitigations recommended by the vendor are active and correctly configured on all affected nodes.
• Access Validation: Use authorized security testing to confirm that path traversal attempts no longer grant unauthorized access to restricted directories.
• File System Integrity: Confirm that the conditions allowing arbitrary file reads (via the chain with CVE-2024-55550) have been neutralized.

Limits and open questions

It remains unclear from the provided data exactly which versions of MiCollab are affected or if a single patch resolves both vulnerabilities in the chain. Furthermore, while mitigations can reduce the likelihood of exploitation, residual risk may remain if the underlying architecture allows for similar traversal patterns. Organizations should note that CISA’s mandated deadlines apply specifically to federal agencies and serve as a risk indicator rather than a universal requirement for private entities.
