How to Fix GHSA-9h6h-9g78-86f7

To remediate this vulnerability, upgrade all affected Github.com/fkie cad/yapscan dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/fkie-cad/yapscan fixed: 0.19.1 
Upgrade github.com/fkie-cad/yapscan to 0.19.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/fkie-cad/yapscan

How to Check if You Are Affected

To determine whether your application is affected by GHSA-9h6h-9g78-86f7, inspect your project dependencies for Github.com/fkie cad/yapscan:

inspect dependencies for github.com/fkie-cad/yapscan

Analyze the terminal output to locate any version of Github.com/fkie cad/yapscan in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.19.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-73: External Control of File Name or Path, where the product allows user input to control or influence paths or file names that are used in filesystem operations. In Github.com/fkie cad/yapscan, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact If you make use of the **report receiver server** (experimental), a client may be able to forge requests such that arbitrary files on the host can be overwritten (subject to permissions of the yapscan server), leading to loss of data. This is particularly problematic if you do not authenticate clients and/or run the server with elevated permissions. ### Patches Vulnerable versions: - v0.18.0 - v0.19.0 (unreleased) This problem is patched in version v0.19.1 ### Workarounds Update to the newer version is highly encouraged! Measures to reduce the risk of this include authenticating clients (see `--client-ca` flag) and containerization of the yapscan server. ### References The tracking issue is #35. There you can find the commits, fixing the issue.
