CVE-2025-12455 is a medium-severity Observable Response Discrepancy (CWE-204) vulnerability in Opentext Vertica. Its CVSS base score is 5.1 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Account Discovery (T1087); ranked at the 23th 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 IA-6 (Authentication Feedback) and SI-11 (Error Handling) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-12455 is an observable response discrepancy vulnerability in OpenText™ Vertica that allows password brute forcing. The issue affects the Vertica management console application in versions from 10.0 through 10.X, from 11.0 through 11.X, and from 12.0 through 12.X.
Unauthenticated remote attackers with network access can exploit this vulnerability due to low attack complexity and no requirement for privileges or user interaction. By observing discrepancies in server responses during authentication attempts, attackers can perform efficient brute force attacks against passwords for the management console, potentially obtaining valid credentials and achieving high confidentiality impact, as reflected in the CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). The vulnerability is classified under CWE-204.

Mitigating Controls (NIST 800-53 r5) AI
Obscuring authentication feedback directly stops one common source of observable response discrepancies.
Error handling explicitly requires messages that avoid revealing exploitable internal information.
Information flow enforcement can block responses that would otherwise disclose internal state to unauthorized parties.
Boundary protection monitors and filters outbound responses that could leak internal state.

Secure SDLC practices directly prevent introduction of inconsistent response behavior that leaks internal state.

Security testing can detect observable response discrepancies before deployment.
Network security controls can enforce uniform responses and suppress observable discrepancies.
Secure SDLC practices include error-handling and response standardization to avoid information disclosure.
Application security requirements typically mandate consistent, non-revealing error messages.
Secure architecture principles discourage designs that leak internal state via differing responses.
Secure coding standards explicitly require uniform error handling to prevent information leakage.
