CVE-2008-2908 in iPrint Client
Summary
by MITRE
Multiple stack-based buffer overflows in a certain ActiveX control in ienipp.ocx in Novell iPrint Client for Windows before 4.36 allow remote attackers to execute arbitrary code via a long value of the (1) operation, (2) printer-url, or (3) target-frame parameter. NOTE: some of these details are obtained from third party information.

The vulnerability identified as CVE-2008-2908 represents a critical stack-based buffer overflow flaw within the Novell iPrint Client ActiveX control component. This issue affects the ienipp.ocx file in Novell iPrint Client versions prior to 4.36 for Windows operating systems. The vulnerability stems from insufficient input validation within the ActiveX control's parameter handling mechanisms, creating a security exposure that can be exploited by remote attackers to execute arbitrary code on affected systems. The flaw specifically manifests when processing three distinct parameters: operation, printer-url, and target-frame, all of which can be manipulated to trigger the buffer overflow condition through the use of excessively long input values.
The technical nature of this vulnerability aligns with CWE-121, which describes stack-based buffer overflow conditions where insufficient bounds checking allows attackers to overwrite adjacent memory locations on the stack. This particular implementation flaw occurs within the ActiveX control's parsing logic, where user-supplied input values are directly copied into fixed-size stack buffers without adequate length validation or sanitization. The exploitation requires minimal privileges since the control operates within the context of the user's session, and successful exploitation can lead to complete system compromise. Attackers can leverage this vulnerability by crafting malicious web pages or network requests that contain oversized parameter values, which when processed by the vulnerable ActiveX control, cause the stack to overflow and potentially execute malicious code with the privileges of the affected user.
The operational impact of CVE-2008-2908 extends beyond simple code execution, as it represents a significant threat vector for privilege escalation and persistent compromise within enterprise environments. Organizations using Novell iPrint Client versions prior to 4.36 face substantial risk exposure, particularly in environments where users may encounter untrusted web content or where the ActiveX control is automatically installed and enabled. The vulnerability's remote exploitability means that attackers can target users from external networks without requiring local access, making it particularly dangerous for remote work environments or public-facing web applications. From an ATT&CK framework perspective, this vulnerability maps to techniques involving exploitation of vulnerabilities and privilege escalation, with potential for lateral movement once initial compromise is achieved. The control's widespread deployment in enterprise printing environments increases the attack surface significantly, as many organizations rely on iPrint Client for network printing functionality.
Mitigation strategies for CVE-2008-2908 should prioritize immediate patching of affected Novell iPrint Client installations to version 4.36 or later, which contains the necessary security fixes. Organizations should also implement browser security controls such as disabling ActiveX controls in web browsers, particularly in environments where users may encounter untrusted content. Network segmentation and access controls can help limit the potential impact of successful exploitation by restricting access to sensitive systems. Security monitoring should include detection of suspicious ActiveX control usage patterns and unusual network activity related to printing services. Additionally, user education regarding the dangers of visiting untrusted websites and opening unknown attachments remains crucial in reducing the attack surface. The vulnerability demonstrates the importance of maintaining up-to-date software components and implementing defense-in-depth strategies to protect against similar ActiveX-based vulnerabilities that may exist in other enterprise applications.
