CVE-2024-55550 (GCVE-0-2024-55550)
Vulnerability from cvelistv5 – Published: 2024-12-10 00:00 – Updated: 2026-08-04 03:55Summary
Mitel MiCollab through 9.8 SP2 could allow an authenticated attacker with administrative privilege to conduct a local file read, due to insufficient input sanitization. A successful exploit could allow the authenticated admin attacker to access resources that are constrained to the admin access level, and the disclosure is limited to non-sensitive system information. This vulnerability does not allow file modification or privilege escalation.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
