Negative charge in shopping cart in Shopizer

CVE-2020-11007 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

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.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
