Vulnerability Note VU#750299
Oracle9i Application Server Apache PL/SQL module vulnerable to buffer overflow via HTTP request
A buffer overflow vulnerability exists in the Apache Procedural Language/Structured Query Language (PL/SQL) module used by Oracle9i Application Server (iAS). A maliciously crafted HTTP request made to the PL/SQL module could cause a denial of service or execute arbitrary code with the privileges of the Apache service.
NGSSoftware has released Insight Security Research Advisory #NISR06022002B, which describes a number of vulnerabilities in the Apache PL/SQL module used by Oracle9i Application Server (iAS). This document addresses a buffer overflow vulnerability caused by a crafted HTTP request made to the PL/SQL module.
Oracle iAS uses the Apache HTTP Server to provide web services, including access to stored procedures via the Oracle PL/SQL module (modpplsql or mod_plsql). In iAS, PL/SQL is used to communicate with the database and generate HTML that can be interpreted by a web browser. A crafted HTTP request made to the PL/SQL module could trigger a buffer overflow, executing arbitrary code with the privileges of the Apache service.
An unauthenticated, remote attacker could cause a denial of service or execute arbitrary code on the system with the privileges of the Apache process. Since the Apache service typically runs with SYSTEM privileges on Windows NT and Windows 2000, an attacker may be able to gain complete control of the system.
