CVE-2012-2194
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 · uneditedDirectory traversal vulnerability in the SQLJ.DB2_INSTALL_JAR stored procedure in IBM DB2 9.1 before FP12, 9.5 through FP9, 9.7 through FP6, 9.8 through FP5, and 10.1 allows remote attackers to replace JAR files via unspecified vectors.
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 confidenceA directory traversal vulnerability exists in the SQLJ.DB2_INSTALL_JAR stored procedure in IBM DB2 versions 9.1 before FP12, 9.5 through FP9, 9.7 through FP6, 9.8 through FP5, and 10.1. The vulnerability allows remote attackers to manipulate file paths and replace JAR files on the system via the stored procedure, potentially leading to code execution or integrity compromise.

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.
-
Check installed DB2 version and fix pack levelRun the command `db2level` from a DB2 command prompt, or query `SELECT service_level, fixpack_num FROM SYSIBMADM.env_inst_info`. Compare the output against the vulnerable ranges: DB2 9.1 before FP12, 9.5 through FP9, 9.7 through FP6, 9.8 through FP5, and 10.1.Affected if The installed version falls within any of these vulnerable version ranges.
-
Verify the SQLJ.DB2_INSTALL_JAR stored procedure existsQuery the system catalog using: `SELECT PROCSCHEMA, PROCNAME FROM SYSCAT.PROCEDURES WHERE PROCSCHEMA = 'SQLJ' AND PROCNAME = 'DB2_INSTALL_JAR'`.Affected if The stored procedure exists in the database.
-
Check execute privileges on the vulnerable stored procedureQuery privilege information using: `SELECT GRANTEE, PROCSCHEMA, PROCNAME, EXECUTEAUTH FROM SYSCAT.PROCAUTH WHERE PROCSCHEMA = 'SQLJ' AND PROCNAME = 'DB2_INSTALL_JAR'`. Review which database users or groups have EXECUTE permission.Affected if Users other than DBADMIN or privileged administrators have EXECUTE permission on SQLJ.DB2_INSTALL_JAR.
-
Confirm JDBC or SQLJ applications can invoke the stored procedureReview application configurations and database connection settings to determine if non-admin applications have the ability to call stored procedures. Check if applications connect with IDs that have been granted execute access to the SQLJ schema.Affected if Applications connect with database IDs that have execute rights on the SQLJ.DB2_INSTALL_JAR procedure.
A user is affected if their DB2 version matches one of the vulnerable release ranges AND the SQLJ.DB2_INSTALL_JAR stored procedure is accessible to users with insufficient privileges.

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 the appropriate IBM DB2 Fix Pack (FP12 for v9.1, FP10 for v9.5, FP7 for v9.7, FP6 for v9.8, and FP2 for v10.1 or later) to address this vulnerability. Additionally, restrict database user privileges to prevent unauthorized access to the SQLJ.DB2_INSTALL_JAR stored procedure.
