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 CVSS score for this vulnerability is 2.7, classified as low severity. Although the severity is low, the risk to organizations includes potential unauthorized access to non-sensitive system information. Organizations should prioritize patching immediately.
The vulnerability was published on December 10, 2024, and is currently included in the Known Exploited Vulnerabilities (KEV) catalog. This inclusion signifies its relevance and potential exploitation in the wild.
Given the administrative privileges required to exploit this vulnerability, organizations must remain vigilant and ensure that only authorized personnel have such access to mitigate the risk of exploitation.
Vulnerability Details
Mitel MiCollab through 9.8 SP2 contains a path traversal vulnerability. The CVSS version used for scoring is 3.1, with a vector string of CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N. This vulnerability is classified under CWE-22, indicating a path traversal issue.
The primary attack vector is network-based, with low attack complexity and requiring high privileges. Importantly, it does not require user interaction. The confidentiality impact is low, while integrity and availability impacts are none.
Technical Analysis
The root cause of this vulnerability is insufficient input sanitization. Attackers may leverage this weakness to read files on the system that should be restricted to administrative access. Given the attack complexity is low, this vulnerability is concerning, especially for organizations relying heavily on Mitel MiCollab.
The attack vector is primarily network-based, allowing potential exploitation without needing physical access to the device. The complexity is low, meaning that even less sophisticated attackers could potentially exploit this vulnerability if they gain administrative access.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to non-sensitive information, potentially leading to further exploitation if combined with other vulnerabilities. The urgency for remediation is high given its classification in the KEV catalog, suggesting active exploitation is possible.
Organizations should address this vulnerability in their priority patch cycle to ensure that administrative access points are secured and that input sanitization mechanisms are adequately enforced.
