CVE-2008-4000
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 · uneditedUnspecified vulnerability in the PeopleTools component in Oracle PeopleSoft Enterprise and JD Edwards EnterpriseOne 8.48.18 and 8.49.14 allows remote attackers to affect confidentiality and integrity via unknown vectors. NOTE: the previous information was obtained from the Oracle October 2008 CPU. Oracle has not commented on reliable researcher claims that this issue allows bypass of the lockout mechanism using brute force guessing of credentials and a response discrepancy information leak when the password is correct.
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 · moderate confidenceVulnerability in PeopleTools component of Oracle PeopleSoft Enterprise and JD Edwards EnterpriseOne (versions 8.48.18 and 8.49.14) allows remote attackers to bypass the account lockout mechanism and perform brute-force credential guessing. A response discrepancy information leak reveals whether a guessed password is correct, enabling attackers to iteratively discover valid credentials without triggering lockouts.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the installed PeopleTools versionLocate the PeopleTools installation directory (PS_HOME) and check the version.properties or version.txt file. Alternatively, log into the PeopleSoft Enterprise Portal as a system administrator and navigate to About > Version to view the PeopleTools release.Affected if The installed PeopleTools version matches exactly 8.48.18 or 8.49.14
-
Identify the JD Edwards EnterpriseOne versionAccess the JD Edwards EnterpriseOne Server and run the 'SVRVER' command or check the registry entry for the EnterpriseOne installation path. The version is typically displayed in the JDE.INI file located in the installation directory.Affected if The installed EnterpriseOne version matches exactly 8.48.18 or 8.49.14
-
Confirm web-based authentication is enabledVerify that the web-based sign-in page for PeopleSoft or JD Edwards is accessible. Try accessing the standard login URL (such as /psp/ps/ for PeopleSoft or /jde/ for JD Edwards). The vulnerability exploits the login response behavior, so web authentication must be enabled for the flaw to apply.Affected if The web-based sign-in interface is exposed and accessible to network users
-
Check the account lockout configurationLog into the PeopleSoft Security Configuration or JD Edwards Security Administrator and review the account lockout settings. Verify the current lockout threshold (number of failed attempts before lockout) and lockout duration values.Affected if Account lockout is configured but the system relies solely on the default PeopleTools lockout mechanism without additional external rate-limiting or monitoring
A system is affected if it runs PeopleTools, PeopleSoft Enterprise, or JD Edwards EnterpriseOne version 8.48.18 or 8.49.14 with the web-based authentication interface exposed and no supplemental brute-force detection in place.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Oracle Critical Patch Update (October 2008 or later) addressing this PeopleTools vulnerability. Implement additional rate-limiting, account lockout monitoring, and Web Application Firewall rules to detect and block credential brute-force attempts until patching is complete.
