Directory Traversal in DotNetZip ZipEntry extraction
CVE-2024-48510 is a directory traversal vulnerability in DotNetZip 1.16.0 and earlier, affecting ZIP extraction logic in src/Zip.Shared/ZipEntry.Extract.cs. A crafted ZIP archive can contain entry names that traverse outside the intended extraction directory. When a victim opens or extracts a malicious archive with an affected version, the library may write attacker-controlled files to arbitrary filesystem locations instead of constraining output to the target extraction path. Because this can place files in executable or otherwise security-sensitive locations, the issue can be leveraged for arbitrary code execution. The available reporting notes that exploitation requires a victim to open a malicious file and that the vulnerable product line is no longer supported by the maintainer.
