Lifecycle Timeline
3DescriptionCVE.org
The login mechanism of Sage DPW 2025_06_004 displays distinct responses for valid and invalid usernames, allowing enumeration of existing accounts in versions before 2021_06_000. On-premise administrators can toggle this behaviour in newer versions.
AnalysisAI
Sage DPW 2025_06_004 and earlier versions enable username enumeration through differential login responses, allowing remote attackers to discover valid user accounts without authentication. The vulnerability affects all versions before 2021_06_000, though on-premise administrators in newer versions can disable this behavior through configuration options.
Technical ContextAI
The vulnerability is a classic username enumeration flaw stemming from information disclosure in the authentication mechanism. The login system returns distinguishable responses for valid versus invalid usernames, violating the principle of consistent error messaging. This allows attackers to systematically probe the application to identify existing accounts. The affected product is Sage DPW (a financial/accounting solution based on the domain sagedpw.at), and the flaw affects versions prior to 2021_06_000. The root cause appears to be insufficient abstraction in error handling during the authentication process, where the application inadvertently leaks information about account existence through response differentiation.
RemediationAI
Upgrade Sage DPW to version 2021_06_000 or later, which includes the ability for on-premise administrators to configure consistent login error responses. For organizations unable to upgrade immediately, on-premise administrators with access to newer versions should enable the configuration option to suppress username enumeration feedback. For versions before 2021_06_000, implement compensating controls such as IP-based rate limiting on login attempts, enforcing CAPTCHA after repeated failures, and monitoring for systematic account enumeration patterns. Consult the vendor advisory at https://www.sagedpw.at/ for specific remediation guidance and patch availability.
