CVE-2008-7093 in Affinium Campaign
Summary
by MITRE
Multiple directory traversal vulnerabilities in Unica Affinium Campaign 7.2.1.0.55 allow remote attackers to (1) create arbitrary directories or files via a .. (dot dot) in the folder name in the new folder functionality or (2) list arbitrary files via a crafted request to Campaign/CampaignListener.

The vulnerability identified as CVE-2008-7093 represents a critical directory traversal flaw affecting Unica Affinium Campaign version 7.2.1.0.55. This security weakness stems from insufficient input validation within the application's folder creation and file listing functionalities, creating exploitable pathways for malicious actors to manipulate the file system through crafted requests. The vulnerability manifests in two distinct attack vectors that collectively enable unauthorized file system manipulation and information disclosure.
The technical implementation of this vulnerability resides in the application's handling of user-supplied directory names during folder creation operations. When users attempt to create new folders through the web interface, the system fails to properly sanitize input containing directory traversal sequences such as ".." characters. This allows attackers to specify folder names that traverse up the directory hierarchy, potentially creating files or directories in unintended locations. The second vector involves the Campaign/CampaignListener endpoint which processes requests without adequate validation of file path parameters, enabling attackers to enumerate arbitrary files on the server filesystem through carefully constructed HTTP requests.
From an operational perspective, this vulnerability presents significant risks to organizations utilizing Unica Affinium Campaign. Attackers exploiting these flaws could gain unauthorized access to sensitive data, potentially leading to data exfiltration, system compromise, or denial of service conditions. The ability to create arbitrary files opens possibilities for code injection attacks, while file listing capabilities enable reconnaissance activities that could reveal system structure, sensitive configuration files, or other confidential information. These vulnerabilities directly impact the confidentiality, integrity, and availability of the affected system, potentially compromising the entire campaign management infrastructure.
Security professionals should consider this vulnerability in the context of CWE-22, which specifically addresses directory traversal weaknesses in software applications. The flaw aligns with ATT&CK technique T1059, representing command and scripting interpreter usage, as attackers may leverage these vulnerabilities to execute malicious code through file system manipulation. Organizations should implement immediate mitigations including input validation and sanitization of all user-supplied directory names, implementing proper path validation to prevent directory traversal sequences from being processed. Additionally, access controls should be strengthened around campaign management interfaces, and network segmentation should be employed to limit exposure of vulnerable components. Regular security assessments and vulnerability management processes should be enhanced to identify similar weaknesses in other applications within the organization's attack surface.
