CVE-2022-36451: n/a in n/a
A vulnerability in the MiCollab Client server component of Mitel MiCollab through 9.5.0.101 could allow an authenticated attacker to conduct a Server-Side Request Forgery (SSRF) attack due to insufficient restriction of URL parameters. A successful exploit could allow an attacker to leverage connections and permissions available to the host server.
AI Analysis
Technical Summary
CVE-2022-36451 is a high-severity vulnerability affecting the MiCollab Client server component of Mitel MiCollab versions up to 9.5.0.101. The vulnerability is classified as a Server-Side Request Forgery (SSRF), which arises from insufficient restrictions on URL parameters within the affected component. SSRF vulnerabilities allow an attacker to induce the server to make HTTP requests to arbitrary domains or internal systems that the attacker would not normally have access to. In this case, the attacker must be authenticated to exploit the vulnerability, but no user interaction is required beyond authentication. Exploiting this flaw could enable an attacker to leverage the server's network permissions and connections, potentially accessing internal resources, sensitive data, or other services behind firewalls that are not directly exposed to the internet. The CVSS v3.1 base score is 8.8, indicating a high severity with the vector string AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, meaning the attack can be performed remotely over the network with low attack complexity, requires low privileges (authenticated user), no user interaction, and impacts confidentiality, integrity, and availability with high severity. The vulnerability is related to CWE-918 (Server-Side Request Forgery). No known exploits in the wild have been reported yet, and no official patches or mitigation links were provided in the source data. The vulnerability was published on October 25, 2022, and is recognized by CISA as enriched data, indicating its relevance and potential risk. Given the nature of Mitel MiCollab as a unified communications platform widely used in enterprise environments for voice, video, and messaging services, exploitation could lead to significant compromise of internal communications infrastructure and sensitive organizational data.
Potential Impact
For European organizations, the impact of CVE-2022-36451 could be substantial due to the widespread use of Mitel MiCollab in corporate telephony and collaboration environments. Successful exploitation could allow attackers to bypass network segmentation by leveraging the server's ability to make requests to internal systems, potentially accessing confidential information, internal APIs, or administrative interfaces not exposed externally. This could lead to data breaches, espionage, disruption of communication services, or lateral movement within the network. The compromise of communication infrastructure can severely impact business continuity, especially in sectors relying heavily on secure and reliable communications such as finance, healthcare, government, and critical infrastructure. Additionally, the high impact on confidentiality, integrity, and availability means that attackers could exfiltrate sensitive data, manipulate communication flows, or cause denial of service conditions. Given the authentication requirement, insider threats or compromised credentials increase the risk, but phishing or credential theft could also enable external attackers to exploit this vulnerability. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as threat actors often develop exploits after vulnerability disclosures. European organizations must consider this vulnerability seriously due to the potential for significant operational and reputational damage.
Mitigation Recommendations
To mitigate CVE-2022-36451 effectively, European organizations should: 1) Immediately verify the version of Mitel MiCollab in use and prioritize upgrading to a version where this vulnerability is patched once available. Since no patch links were provided, organizations should consult Mitel's official security advisories and support channels for updates or workarounds. 2) Restrict and monitor authenticated user access to the MiCollab Client server component, enforcing the principle of least privilege to minimize the number of users who can exploit this SSRF vulnerability. 3) Implement network segmentation and firewall rules to limit the MiCollab server's ability to initiate outbound requests to sensitive internal systems or critical infrastructure, effectively reducing the attack surface for SSRF exploitation. 4) Deploy robust logging and monitoring to detect unusual outbound requests from the MiCollab server, which may indicate exploitation attempts. 5) Use multi-factor authentication (MFA) to reduce the risk of credential compromise that could enable attackers to gain the required authenticated access. 6) Conduct regular security assessments and penetration testing focusing on SSRF and related vulnerabilities within the communication infrastructure. 7) Educate users and administrators about the risks of credential phishing and enforce strong password policies to prevent unauthorized access. These targeted actions go beyond generic advice by focusing on access control, network restrictions, and proactive detection tailored to the nature of this SSRF vulnerability in a communications platform.
