Summary

CVE-2025-32378 is a medium-severity Improper Control of Interaction Frequency (CWE-799) vulnerability in Shopware Shopware. Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 21th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-10 (Concurrent Session Control) and AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

Vulnerability Data

Shopware is an open source e-commerce software platform. Prior to 6.6.10.3 or 6.5.8.17, the default settings for double-opt-in allow for mass unsolicited newsletter sign-ups without confirmation. Default settings are Newsletter: Double Opt-in set to active, Newsletter: Double opt-in for registered…

customers set to disabled, and Log-in & sign-up: Double opt-in on sign-up set to disabled. With these settings, anyone can register an account on the shop using any e-mail-address and then check the check-box in the account page to sign up for the newsletter. The recipient will receive two mails confirming registering and signing up for the newsletter, no confirmation link needed to be clicked for either. In the backend the recipient is set to “instantly active”. This vulnerability is fixed in 6.6.10.3 or 6.5.8.17.

MITRE ATT&CK Enterprise Techniques

T1110 Brute Force Credential Access
Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.
T1499.002 Service Exhaustion Flood Impact
Adversaries may target the different network services provided by systems to conduct a denial of service (DoS).
T1499.003 Application Exhaustion Flood Impact
Adversaries may target resource intensive features of applications to cause a denial of service (DoS), denying availability to those applications.
T1667 Email Bombing Impact
Adversaries may flood targeted email addresses with an overwhelming volume of messages.
T1110.001 Password Guessing Credential Access
Adversaries with no prior knowledge of legitimate credentials within the system or environment may guess passwords to attempt access to accounts.
T1110.003 Password Spraying Credential Access
Adversaries may use a single or small list of commonly used passwords against many different accounts to attempt to acquire valid account credentials.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

ac-10 enforces a hard limit on concurrent sessions per user, directly stopping uncontrolled interaction frequency at the session level.

ac-7 directly enforces a limit on the frequency of invalid authentication attempts, structurally preventing the weakness for that interaction class.

sc-5 reduces the impact of excessive request volume (DoS) but does not itself impose the frequency controls whose absence defines the weakness.

Protecting networks from unauthorized usage can incorporate rate limiting to bound interaction frequency.

mitigates

Network security controls can enforce rate limiting and throttling at the perimeter.

prevents

Application security requirements explicitly include controls on interaction frequency and throttling.

prevents

Secure architecture principles recommend rate-limiting and resource-management mechanisms.

prevents

Secure coding practices can embed input-frequency and throttling checks in code.

degrades

Capacity management directly limits request rates and resource exhaustion that CWE-799 describes.
