CVE-2009-1569 in iPrint
Summary
by MITRE
Multiple stack-based buffer overflows in Novell iPrint Client 4.38, 5.30, and possibly other versions before 5.32 allow remote attackers to execute arbitrary code via vectors related to (1) Date and (2) Time.

The vulnerability identified as CVE-2009-1569 represents a critical stack-based buffer overflow flaw affecting Novell iPrint Client versions 4.38, 5.30, and potentially earlier releases before 5.32. This vulnerability exposes the client software to remote code execution attacks through specifically crafted Date and Time data inputs. The issue stems from inadequate input validation mechanisms within the iPrint client implementation, particularly when processing time-related information from network sources. Such buffer overflows occur when the application attempts to write more data into a fixed-length memory buffer than it can accommodate, leading to memory corruption that attackers can exploit to gain control over the affected system.
The technical exploitation of this vulnerability leverages the fundamental weakness in memory management practices within the iPrint client software. When the client processes network data containing malformed Date and Time parameters, the application fails to properly bounds-check the input data before copying it into stack-based buffers. This flaw creates an opportunity for attackers to overwrite adjacent memory locations, potentially including return addresses and control flow information. The attack vector operates remotely, meaning that malicious actors can trigger the vulnerability without requiring physical access to the target system, making it particularly dangerous in networked environments where print services are commonly exposed. This vulnerability aligns with CWE-121 stack-based buffer overflow classification and represents a significant concern for enterprise environments that rely on Novell iPrint for document management and printing services.
The operational impact of CVE-2009-1569 extends beyond simple code execution capabilities, as successful exploitation can lead to complete system compromise. Attackers who successfully exploit this vulnerability can gain arbitrary code execution privileges on the targeted system, potentially allowing them to install malware, establish persistent backdoors, or escalate privileges to administrator levels. The vulnerability affects organizations that depend on Novell iPrint Client for their printing infrastructure, particularly those with remote access capabilities or exposed print servers. The remote nature of the attack means that organizations may be vulnerable even when their network perimeters appear secure, as the vulnerability can be triggered through network-based attacks targeting print services. This makes the vulnerability particularly attractive to threat actors seeking to establish footholds within enterprise networks.
Organizations should prioritize immediate remediation through official vendor patches and updates to address this vulnerability. The recommended mitigation strategy involves upgrading to Novell iPrint Client version 5.32 or later, which contains the necessary fixes for the buffer overflow conditions. System administrators should also implement network segmentation and access controls to limit exposure of print services to untrusted networks. Additional defensive measures include monitoring network traffic for suspicious Date and Time data patterns, implementing intrusion detection systems, and conducting regular vulnerability assessments of print infrastructure components. Security teams should also consider disabling unnecessary print services and implementing network access controls to prevent unauthorized access to print servers. The vulnerability demonstrates the importance of proper input validation and memory management practices in client applications, particularly those handling network data from untrusted sources, and aligns with ATT&CK technique T1059.007 for command and scripting interpreter usage in exploitation scenarios.
