Detailsinfo

A vulnerability, which was classified as very critical, was found in Oracle Database Server 12.1.0.1 (Database Software). This affects an unknown function of the component XML Parser. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Unspecified vulnerability in the XML Parser component in Oracle Database Server 11.2.0.2, 11.2.0.3, and 12.1.0.1 allows remote authenticated users to affect confidentiality, integrity, and availability via unknown vectors.

The weakness was presented 07/16/2014 as Oracle Critical Patch Update Advisory - July 2014 as confirmed advisory (Website). The advisory is shared at oracle.com. Daniel Wesemann at ISC writes in a blog post: "Looks like the Oracle 12 code was forked before the 11g patch went in, and nobody ported it over, so Oracle 12 remained exposed to the same bug until now. This speaks volumes about Oracle's software development life cycle and security processes..." This vulnerability is uniquely identified as CVE-2013-3751 since 06/03/2013. The exploitability is told to be easy. It is possible to initiate the attack remotely. The successful exploitation requires a authentication. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 02/08/2022). MITRE ATT&CK project uses the attack technique T1068 for this issue.

We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 68934 (Oracle Database Multiple Vulnerabilities (July 2013 CPU)), which helps to determine the existence of the flaw in a target environment.
