How to Fix CVE-2022-21687

To remediate this vulnerability, upgrade all affected Github.com/github/gh ost 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/github/gh-ost fixed: 1.1.3 
Upgrade github.com/github/gh-ost to 1.1.3
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/github/gh-ost

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-21687, inspect your project dependencies for Github.com/github/gh ost:

inspect dependencies for github.com/github/gh-ost

Analyze the terminal output to locate any version of Github.com/github/gh ost in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.3), 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Github.com/github/gh ost, 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

Gh-ost version <= 1.1.2 allows users to inject DSN strings via the `-database` parameter. This is a low severity vulnerability as the attacker must have access to the target host or trick an administrator into executing a malicious `gh-ost` command on a host running `gh-ost`, plus network access from host running `gh-ost` to the attack's malicious MySQL server. ### Impact This issue may lead to arbitrary local file read. ### Patches Fixed in 1.1.3+. ### Workarounds None ### References - https://advisory.dw1.io/51 ### For more information If you have any questions or comments about this advisory: * Open an issue in [github/gh-ost](http://github.com/github/gh-ost)
