CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2022-27925 is a high-severity Path Traversal (CWE-22) vulnerability in Synacor Zimbra Collaboration Suite. Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Zimbra Collaboration Suite (ZCS) versions 8.8.15 and 9.0 contain a path traversal flaw in the mboximport component. The function accepts a ZIP archive from an authenticated caller and extracts its contents without properly sanitizing file paths, enabling an administrator to write arbitrary files outside the intended directory.
An attacker who already possesses administrator credentials can upload a crafted ZIP archive through the mboximport interface. Successful exploitation grants the ability to place files anywhere on the filesystem, which, given the CVSS vector (AV:N/AC:L/PR:H), can result in full control over confidentiality, integrity, and availability of the ZCS installation.
Zimbra’s security advisories and release notes direct administrators to apply the fixes shipped in the P24 patch for the 9.0 branch and corresponding updates for 8.8.15; the wiki pages also list the affected builds and the corrected versions.
The CVE carries an EPSS score that has reached a peak of 0.9732 and currently stands at 0.9431, reflecting sustained exploitation interest after disclosure. Public proof-of-concept material is available on Packet Storm, and Zimbra has published corresponding security-center entries.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Validates pathnames and filenames to prevent traversal outside intended directories.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.
PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
