CVE-2021-37701

A flaw was found in the npm package "tar" aka node-tar. Extracting tar files that contain both a directory and a symlink with the same name, where the symlink and directory names in the archive entry used backslashes as a path separator, made it possible to bypass node-tar symlink checks on...

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...

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...

Improper Handling of Case Sensitivity

Istio is an open source platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. According to RFC 4343, Istio authorization policy should compare the hostname in the HTTP Host header in a case...

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...

istio/istio: HTTP request can bypass authorization mechanisms due to case insensitive host comparison

An authorization bypass vulnerability was found in istio/istio. The case insensitive host comparison incorrectly works when evaluating rules specified with host or notHost. This flaw allows an attacker to bypass an Istio authorization policy that uses hosts in the rules, potentially gaining acces...

libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup.Due to errors in the logic the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*which could lead to libcurl reusing wrong connections.File paths are or can be case sensitive on many systems but not all and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate.
