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
Unspecified vulnerability in the Oracle Reports Developer component in Oracle Fusion Middleware 11.1.1.4, 11.1.1.6, and 11.1.2.0 allows remote attackers to affect confidentiality and integrity via unknown vectors related to Report Server Component. NOTE: the previous information is from the October 2012 CPU. Oracle has not commented on claims from the original researcher that the URLPARAMETER functionality allows remote attackers to read and upload arbitrary files to reports/rwservlet, and that this issue occurs in earlier versions. NOTE: this can be leveraged with CVE-2012-3153 to execute arbitrary code by uploading a .jsp file.

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

Arbitrary file read/write vulnerability in Oracle Reports Developer (rwservlet) via the URLPARAMETER functionality. Allows remote unauthenticated attackers to read and upload files to the reports server, which can be chained with CVE-2012-3153 to achieve remote code execution via JSP file upload.

MitigationApply Oracle Critical Patch Update October 2012 or later. If patching is not immediately feasible, disable or restrict rwservlet access via web server configuration and implement network-level access controls.

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 Fusion Middleware installation
    Check for Oracle Fusion Middleware installation directories, typically under $ORACLE_HOME (e.g., /u01/oracle/fmw, C:\oracle\fmw, or similar). Look for the 'reports' component directory within the Middleware home.
    Affected if Fusion Middleware is installed and the reports component exists in the ORACLE_HOME directory.
  2. Determine Fusion Middleware version
    Check the version file in the Middleware home, usually located at ORACLE_HOME/oraInst.loc or check the inventory file at $ORACLE_HOME/oraInventory/ContentsXML/inventory.xml. Compare the installed version to 11.1.1.4.0, 11.1.1.6.0, or 11.1.2.0.
    Affected if The installed Fusion Middleware version exactly matches 11.1.1.4.0, 11.1.1.6.0, or 11.1.2.0.
  3. Verify Oracle Reports (rwservlet) is configured
    Check if the rwservlet is configured by looking for the reports configuration files in $ORACLE_HOME/reports/conf or by checking the Oracle Enterprise Manager for Reports Server component status. Look for rwservlet configuration in the reports web tier (usually under $ORACLE_HOME/reports/tools/reportsadmin/rwservlet).
    Affected if The rwservlet component is installed and configured as part of the Fusion Middleware installation.
  4. Check if rwservlet is network accessible
    Test access to the rwservlet endpoint by making an HTTP/HTTPS request to the reports server URL, typically at /reports/rwservlet. For example: http://target-host:port/reports/rwservlet. If the server responds (even with an error), the endpoint is exposed.
    Affected if The rwservlet is accessible over the network (HTTP/HTTPS) on any port, indicating the vulnerable component is exposed.
  5. Test for vulnerable URLPARAMETER functionality
    Send a test request to the rwservlet with a URLPARAMETER argument containing directory traversal sequences, such as: /reports/rwservlet?URLPARAMETER=../../../../etc/passwd. A vulnerable server will attempt to access or process the specified path.
    Affected if The server accepts and processes URLPARAMETER requests with directory traversal sequences (../) without rejecting them, indicating the vulnerability is present and exploitable.

The environment is affected if Oracle Fusion Middleware versions 11.1.1.4.0, 11.1.1.6.0, or 11.1.2.0 are installed with the rwservlet component exposed on the network, and the server accepts directory traversal sequences in the URLPARAMETER parameter.

Interim mitigation

Apply Oracle Critical Patch Update October 2012 or later. If patching is not immediately feasible, disable or restrict rwservlet access via web server configuration and implement network-level access controls.

Recommended fix High confidence

Oracle Fusion Middleware 11g (11.1.1.9.0) or later stable release, or migrate to Oracle Fusion Middleware 12c/13c as end of support for 11g approaches

  1. 1. Navigate to Oracle Support (support.oracle.com) and sign in with your Oracle Single Sign-On account.
  2. 2. Search for Oracle Critical Patch Update October 2012 (or CVE-2012-3152).
  3. 3. Download the relevant patch for your specific Fusion Middleware version (11.1.1.4.0, 11.1.1.6.0, or 11.1.2.0).
  4. 4. Review the patch README for any pre-installation requirements or prerequisites.
  5. 5. Stop all Oracle Fusion Middleware services, including Oracle Reports Server and Oracle WebLogic Server domains.
  6. 6. Apply the patch using OPatch: Run 'opatch apply' from the patch directory as the Oracle software owner.
  7. 7. After patch application completes successfully, restart all Fusion Middleware services.
  8. 8. Verify the patch was applied by running 'opatch lsinventory' and confirming the patch is listed.
Caveat Patch application carries moderate risk of service interruption and should be tested in a non-production environment first; review Oracle CPU patch pre-install notes for any compatibility concerns
