CVE-2024-42355 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Impact

Shopware has a new Twig Tag sw_silent_feature_call which silences deprecation messages while triggered in this tag.
It accepts as parameter a string the feature flag name to silence, but this parameter is not escaped properly and allows execution of code.

Patches

Update to Shopware 6.6.5.1 or 6.5.8.13

Workarounds

For older versions of 6.2, 6.3, and 6.4, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.

Base score Version Severity Vector
8.3 3.1 —
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L Click to expand
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:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
