Oracle Database Server 10.1.0.5 AUTH_SESSKEY Remote Code Execution

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as very critical was found in Oracle Database Server 10.1.0.5 (Database Software). This vulnerability affects an unknown function. The manipulation of the argument AUTH_SESSKEY with an unknown input leads to a remote code execution vulnerability. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Unspecified vulnerability in the Network Authentication component in Oracle Database 10.1.0.5 and 10.2.0.4 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the October 2009 CPU. Oracle has not commented on claims from an independent researcher that this is related to improper validation of the AUTH_SESSKEY parameter length that leads to arbitrary code execution.

The weakness was shared 10/21/2009 by Dennis Yurichev with Oracle (Website). The advisory is available at us-cert.gov. This vulnerability was named CVE-2009-1979. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details and also a public exploit are known. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 08/24/2021).

A public exploit has been developed by Dennis Yurichev in C++ and been published 2 weeks after the advisory. It is possible to download the exploit at securityfocus.com. It is declared as highly functional. As 0-day the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 56066 (Oracle Database Multiple Vulnerabilities (October 2009 CPU)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Databases. The commercial vulnerability scanner Qualys is able to test this issue with plugin 19575 (Oracle Database October 2009 Patch Set Update (PSU) 10.2.0.4.2 Not Installed (Patch 8833280)).

A possible mitigation has been published even before and not after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 9414.

The vulnerability is also documented in the databases at Tenable (56066) and Exploit-DB (9905). The entries 50583, 50582, 50581 and 50580 are related to this item.
