Arbitrary File Creation/Overwrite via insufficient symlink protection due to directory cache poisoning using symbolic links

Impact Arbitrary File Creation, Arbitrary File Overwrite, Arbitrary Code Execution node-tar aims to guarantee that any file whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by ensuring that extracted directories are not symlinks. Additionally, in...

PT-2021-22396 · Npm +3 · @Npmcli/Arborist +4

Name of the Vulnerable Software and Affected Versions: @npmcli/arborist versions prior to 2.8.2 npm versions prior to 7.20.7 Description: The issue arises from how @npmcli/arborist handles package dependencies on case-insensitive file systems, such as macOS and Windows. When multiple dependencies...

CVE-2021-37701

The npm package "tar" aka node-tar before versions 4.4.16, 5.0.8, and 6.1.7 has an arbitrary file creation/overwrite and arbitrary code execution vulnerability. node-tar aims to guarantee that any file whose location would be modified by a symbolic link is not extracted. This is, in part, achieve...

Authorization Policy Bypass Due to Case Insensitive Host Comparison

Impact According to RFC 4343, Istio authorization policy should compare the hostname in the HTTP Host header in a case insensitive way, but currently the comparison is case sensitive. The Envoy proxy will route the request hostname in a case-insensitive way which means the authorization policy...

Git LFS Clone Command Exec

Git clients that support delay-capable clean / smudge filters and symbolic links on case-insensitive file systems are vulnerable to remote code execution while cloning a repository. Usage of clean / smudge filters through Git LFS and a case-insensitive file system changes the checkout order of...

Privilege Escalation

github.com/istio/istio is vulnerable to privilege escalation. Lack of case-sensitive comparison of hostname in the HTTP Host header allows an attacker to bypass the authorization policy as it causes the Envoy proxy to route the request hostname in a case-insensitive way...
