GHSA-w8rc-pgxq-x2cjNegative charge in shopping cart in Shopizer2020-04-22ghsa · osvUS
### Impact Using API or Controller based versions negative quantity is not adequately validated hence creating incorrect shopping cart and order total. ### Patches Adding a back-end verification to check that quantity parameter isn't negative. If so, it is set to 1. Patched in 2.11.0 ### Workarounds Without uprading, it's possible to just apply the fixes in the same files it's done for the patch. Or you use javax constraint validation on the quantity parameter. ### References [Input Validation](https://cheatsheetseries.owasp.org/cheatsheets/Input_Validation_Cheat_Sheet.html) [Using bean validation constraint](https://javaee.github.io/tutorial/bean-validation002.html) [Commits with fixes](https://github.com/shopizer-ecommerce/shopizer/commit/929ca0839a80c6f4dad087e0259089908787ad2a) CVE Details below : [Mitre](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-11007) [NVD](https://nvd.nist.gov/vuln/detail/CVE-2020-11007) ### Credits Found and solved by Yannick Gosset from Aix-Marseille University cybersecurity master program supervised by Yassine Ilmi
