CVE-2006-1137 in Copycentre C75
Summary
by MITRE
Multiple unspecified vulnerabilities in Xerox CopyCentre and Xerox WorkCentre Pro, running software 1.001.02.073 or earlier, or 1.001.02.074 before 1.001.02.715, allow remote attackers to cause an unspecified denial of service via a crafted PostScript file that will (1) "navigate through the directory" or (2) a "file sent to expose TCP/IP ports".

The vulnerability identified as CVE-2006-1137 affects Xerox CopyCentre and Xerox WorkCentre Pro devices operating on specific software versions, representing a significant security weakness in enterprise printing infrastructure. These multifunction devices, widely deployed in corporate environments, serve as critical points of access for document processing and network connectivity, making their security paramount to overall organizational defense. The affected software versions include 1.001.02.073 and earlier releases, as well as 1.001.02.074 through 1.001.02.714, indicating a broad range of impacted firmware that could potentially expose numerous networked printing systems to attack.
The technical flaw manifests through two distinct attack vectors that exploit weaknesses in how these devices process PostScript files, a widely used page description language in professional printing environments. The first vector involves directory traversal attacks that allow malicious actors to navigate through the device's file system hierarchy, potentially accessing sensitive configuration files or system resources that should remain protected. This type of vulnerability aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks. The second vector involves sending crafted files that can expose TCP/IP ports on the device, effectively creating unauthorized network access points that could be leveraged for further reconnaissance or exploitation activities.
The operational impact of this vulnerability extends beyond simple denial of service, as it creates potential pathways for attackers to gain unauthorized access to networked printing systems that often serve as entry points into broader corporate networks. These devices frequently operate with elevated privileges and may have access to sensitive network resources, making them attractive targets for attackers seeking to establish persistent access or escalate privileges. The vulnerability's potential to cause unspecified denial of service represents a serious concern for organizations that rely on continuous printing operations, as it could disrupt critical business processes and document workflows. Additionally, the exposure of TCP/IP ports through these attacks could enable attackers to conduct further network reconnaissance, potentially identifying other vulnerable systems within the organization's network infrastructure.
Organizations should prioritize immediate remediation of affected devices through firmware updates provided by Xerox, as these vulnerabilities represent a clear threat to network security and operational continuity. The implementation of network segmentation and access controls around these devices can provide additional layers of protection, while monitoring for unusual network traffic patterns or unauthorized access attempts should be established. From a broader security perspective, this vulnerability highlights the importance of securing networked printing infrastructure, which often receives less attention than other network components despite serving as potential attack vectors. The attack vectors described in CVE-2006-1137 align with techniques documented in the MITRE ATT&CK framework under the T1071.004 sub-technique for application layer protocol: DNS, where attackers may leverage network services to establish command and control channels or conduct reconnaissance activities. Regular security assessments of print server configurations and implementation of secure printing practices should be considered as part of comprehensive network security strategies to address similar vulnerabilities in other enterprise devices.
