The vulnerability described in CVE-2002-0947 represents a critical buffer overflow flaw within the rwcgi60 CGI program component of Oracle Reports Server version 6.0.8.18.0 and earlier releases. This issue affects Oracle9iAS and related products, making it a significant concern for organizations utilizing Oracle's web application server infrastructure. The vulnerability exists in the handling of database name parameters within the CGI program, which processes web requests for Oracle Reports functionality.
The technical implementation of this buffer overflow stems from inadequate input validation within the rwcgi60 CGI executable. When a remote attacker submits a specially crafted request containing an excessively long database name parameter, the program fails to properly bounds-check the input data before copying it into a fixed-size buffer. This classic programming error allows the attacker to overwrite adjacent memory locations, potentially corrupting the program's execution flow and enabling arbitrary code execution. The vulnerability operates at the application layer and requires no authentication to exploit, making it particularly dangerous in networked environments.
From an operational perspective, this vulnerability poses severe risks to affected systems as it enables remote code execution without requiring user credentials or privileged access. Attackers can leverage this weakness to gain full control over the affected Oracle Reports Server instance, potentially leading to complete system compromise, data exfiltration, or use as a foothold for further attacks within the network. The impact extends beyond individual server compromise to potentially affect entire Oracle9iAS deployments, given the widespread use of this component across various Oracle products. Organizations running vulnerable versions face significant exposure to sophisticated attacks targeting their reporting infrastructure.
The mitigation strategies for CVE-2002-0947 involve immediate patching of affected Oracle Reports Server installations to versions that address the buffer overflow vulnerability. Organizations should also implement network segmentation to limit access to Oracle9iAS components, deploy web application firewalls to monitor and filter suspicious requests, and conduct thorough security assessments of their Oracle infrastructure. Additionally, disabling unnecessary CGI programs and implementing strict input validation measures can reduce the attack surface. This vulnerability aligns with CWE-121, which addresses stack-based buffer overflow conditions, and maps to ATT&CK technique T1059.007 for command and scripting interpreter, as attackers can execute arbitrary code through the compromised CGI interface. Regular security updates and vulnerability management processes are essential to prevent exploitation of similar buffer overflow vulnerabilities in Oracle products and related web applications.
