Detailsinfo

A vulnerability has been found in Oracle9i 9.0/9.0.1/9.0.1.2/9.0.1.3/9.0.2 (Database Software) and classified as very critical. Affected by this vulnerability is some unknown processing of the file ORACLE.EXE of the component Authentication. The manipulation of the argument Username with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in ORACLE.EXE for Oracle Database Server 9i, 8i, 8.1.7, and 8.0.6 allows remote attackers to execute arbitrary code via a long username that is provided during login, as exploitable through client applications that perform their own authentication, as demonstrated using LOADPSP.

The weakness was presented 02/16/2003 by Mark Litchfield as confirmed advisory (CERT.org). The advisory is shared at kb.cert.org. This vulnerability is known as CVE-2003-0095. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details and also a exploit are known. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/25/2025).

After immediately, there has been an exploit disclosed. It is declared as proof-of-concept. The commercial vulnerability scanner Qualys is able to test this issue with plugin 19079 (Oracle Database Server ORACLE.EXE Buffer Overflow Vulnerability).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product. Attack attempts may be identified with Snort ID 2650. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 3587.

The vulnerability is also documented in the databases at X-Force (11328), SecurityFocus (BID 6849†), OSVDB (6319†), Secunia (SA7443†) and Vulnerability Center (SBV-3952†).
