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
Multiple CRLF injection vulnerabilities in Oracle Portal 9.0.2 and possibly other versions allow remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via CRLF sequences in the enc parameter to (1) calendarDialog.jsp or (2) fred.jsp. NOTE: the calendar.jsp vector is covered by CVE-2006-6697.

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

Oracle Portal 9.0.2 contains CRLF injection vulnerabilities in calendarDialog.jsp and fred.jsp. The 'enc' parameter fails to sanitize CRLF sequences, allowing remote attackers to inject arbitrary HTTP headers and perform HTTP response splitting attacks.

MitigationApply Oracle security patches for this vulnerability. If patches are unavailable, implement input validation to reject or sanitize CRLF sequences in the 'enc' parameter, or consider upgrading to a supported Oracle Portal version.

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 Oracle Portal installation
    Locate Oracle Application Server Portal installation directory and check version information in ORACLE_HOME/portal/conf or via Oracle Enterprise Manager
    Affected if Version is exactly 9.0.2
  2. Locate vulnerable JSP files
    Search for calendarDialog.jsp and fred.jsp in the portal web document root (typically under ORACLE_HOME/portal/webapps/portal/ or similar path)
    Affected if Either calendarDialog.jsp or fred.jsp exists in the portal deployment
  3. Verify portal is network accessible
    Check if the portal HTTP listener is bound to a network interface and accessible from outside localhost
    Affected if Portal is exposed on a reachable network address
  4. Test enc parameter for CRLF injection
    Send HTTP request to calendarDialog.jsp or fred.jsp with enc parameter containing CRLF sequences (e.g., enc=test%0D%0AHeader:value) and observe if headers are injected into response
    Affected if Application accepts and reflects unsanitized CRLF in the enc parameter

If Oracle Application Server Portal 9.0.2 is running with the vulnerable JSP files (calendarDialog.jsp or fred.jsp) accessible on the network, the environment is affected by this CRLF injection vulnerability.
