Oracle E-Business Suite 11.5.7 PL/SQL Module WE8ISO8859P1 Character Set privileges management

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 was found in Oracle E-Business Suite 11.5.7 (Supply Chain Management Software). It has been classified as critical. This affects some unknown processing of the component PL/SQL Module. The manipulation as part of a WE8ISO8859P1 Character Set 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:

The PL/SQL module for the Oracle HTTP Server in Oracle Application Server 10g, when using the WE8ISO8859P1 character set, does not perform character conversions properly, which allows remote attackers to bypass access restrictions for certain procedures via an encoded URL with "%FF" encoded sequences that are improperly converted to "Y" characters.

The bug was discovered 12/23/2004. The weakness was presented 08/04/2004 by Esteban Martinez Fayo (Alex) (Website). The advisory is shared at us-cert.gov. This vulnerability is uniquely identified as CVE-2004-1362 since 01/07/2005. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue.

A public exploit has been developed in SQL. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 23409 (Solaris 8 (sparc) : 118828-04), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Solaris Local Security Checks and running in the context l.

Applying a patch is able to eliminate this problem. A possible mitigation has been published 11 months after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 2686. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 2970.

The vulnerability is also documented in the databases at X-Force (18657) and Tenable (23409). See 1618, 21994, 21995 and 21996 for similar entries.
