CVE-2006-0547

Oracle Database 8i, 9i, and 10g allow remote authenticated users to execute arbitrary SQL statements in the context of the SYS user and bypass audit logging, including statements to create new privileged database accounts, via a modified AUTH_ALTER_SESSION attribute in the authentication phase of the Transparent Network Substrate (TNS) protocol. NOTE: due to the lack of relevant details from the Oracle advisory, a separate CVE is being created since it cannot be conclusively proven that this issue has been addressed by Oracle. It is possible that this is the same issue as Oracle Vuln# DB18 from the January 2006 CPU, in which case this would be subsumed by CVE-2006-0265.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For oracle's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
