Security readout for executives and security teams
Plain-English summary
This CVE is a Zip-Slip flaw in DotNetZip.Semvered before 1.11.0. If a user or system extracts a malicious ZIP with the vulnerable library, files can be written outside the intended folder, potentially overwriting important application files.
Executive priority
Prioritize remediation for systems that accept external ZIP files or automate archive ingestion. This is not marked as actively exploited, but the business impact can be serious if file overwrite affects application integrity.
Technical view
The vulnerable extraction logic mishandles archive entry paths containing parent-directory traversal. The CVSS vector is local, low complexity, no privileges required, and user interaction required, with high integrity impact. Sources identify the issue as CWE-22 and a fix associated with version 1.11.0.
Likely exposure
Exposure is likely where .NET applications use DotNetZip.Semvered before 1.11.0 to extract ZIP files from users, partners, email, uploads, or automated import pipelines.
Exploitation context
The source bundle does not show active exploitation, and KEV is false. Abuse requires a crafted ZIP archive being extracted by a vulnerable application context.
Researcher notes
Focus validation on vulnerable dependency presence and archive extraction trust boundaries. The evidence supports arbitrary file write through directory traversal during extraction, but does not provide environment-specific exploitability or active exploitation evidence.
Mitigation direction
- Upgrade DotNetZip.Semvered to version 1.11.0 or later.
- Avoid extracting untrusted ZIP files with affected versions.
- Run archive extraction with least privilege and isolated working directories.
- Review vendor guidance and the linked fix before accepting compensating controls.
Validation and detection
- Check dependency manifests and lock files for DotNetZip.Semvered versions before 1.11.0.
- Identify application paths that extract ZIP files from untrusted sources.
- Confirm deployed runtime packages match the fixed dependency version.
- Review extraction code for canonical path checks before file writes.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
