Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In Eclipse GlassFish versions before 8.0.3 it is possible to perform Login Brute Force attacks as there is no limitation in the number of failed login attempts. GlassFish 8.0.3 adds automatic attack protection documented in https://glassfish.org/docs/latest/security-guide.html#brute-force-attack-protection .

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Eclipse GlassFish versions before 8.0.3 lack brute force attack protection, allowing unlimited failed login attempts on the admin console and other authentication endpoints. This enables attackers to systematically guess credentials without any account lockout or rate limiting, potentially leading to unauthorized administrative access.

MitigationUpgrade to GlassFish 8.0.3 or later, which includes built-in automatic brute force attack protection as documented in the security guide.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed GlassFish version
    Run 'asadmin version' from the GlassFish bin directory, or check the glassfish/lib/asenv.bat/asenv file for version information, or inspect the glassfish-*.jar file in the lib directory
    Affected if Version is 7.0.16 or any version below 8.0.3
  2. Verify admin console is accessible
    Attempt to access the GlassFish admin console URL (typically http://localhost:4848 or https://localhost:4848) from a browser or curl command
    Affected if Admin console responds and presents a login form
  3. Confirm no rate limiting on authentication endpoints
    Review the domain.xml configuration file (in glassfish/domains/domain1/config/domain.xml) for any <security> or <login-config> elements that enforce account lockout or rate limiting. Also check web.xml for any login-related constraints.
    Affected if No account-lockout, max-failures, or rate-limiting elements are present in the authentication configuration
  4. Test login failure behavior
    Send multiple failed login attempts to the admin console endpoint (e.g., using curl or a script to POST credentials repeatedly) and observe whether attempts are throttled, delayed, or blocked
    Affected if Failed login attempts are accepted without any delay, throttling, or account lockout after repeated failures

The environment is affected if running GlassFish version 7.0.16 or earlier with the admin console accessible and no account lockout or rate limiting configured on authentication endpoints.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to GlassFish 8.0.3 or later, which includes built-in automatic brute force attack protection as documented in the security guide.

Recommended fix High confidence

GlassFish 8.0.3 or later

  1. Upgrade Eclipse GlassFish to version 8.0.3 or later to obtain the built-in brute force attack protection
  2. After upgrading, verify that brute force attack protection is enabled by default per the security guide at https://glassfish.org/docs/latest/security-guide.html#brute-force-attack-protection
