Team SHATTER Security Advisory
Multiple DoS in JAR files manipulation procedures
April 17th 2008
Risk Level: High
Affected versions: All versions of IBM DB2 Database Server on Windows platform.
Remote exploitable: Yes (Authentication to Database Server is needed)
Credits: These vulnerabilities were discovered and researched by Ariel Sanchez of Application Security Inc.
Details: DB2 has multiple vulnerabilities which can lead to Denial of Service (DoS) attacks against the instance. When RECOVERJAR and REMOVE_JAR procedures are called with a specially crafted parameter the DB2 instance crashes. Any DB2 database user can exploit these vulnerabilities since PUBLIC permissions are granted to both procedures by default. The RECOVERJAR and REMOVE_JAR procedures are installed by default.
Impact: Any remote authenticated attacker can crash the DB2 instance.
Vendor Status: Vendor was contacted and a patch was released.
Fix: To fix the problem apply the FP16(v8), FP4a(v9.1) and FP1(v9.5): http://www-1.ibm.com/support/docview.wss?rs=71&uid=swg21256235 http://www-1.ibm.com/support/docview.wss?rs=71&uid=swg21255572 http://www-1.ibm.com/support/docview.wss?rs=71&uid=swg21287889
