CVE-2010-2584 in Module ActiveX Controls
Summary
by MITRE
The Upload method in the RealPage Module Upload ActiveX control in Realpage.dll 1.0.0.9 in RealPage Module ActiveX Controls does not properly restrict certain property values, which allows remote attackers to read arbitrary files via a filename in the SourceFile property in conjunction with an http URL in the DestURL property.

The vulnerability identified as CVE-2010-2584 resides within the RealPage Module Upload ActiveX control, specifically in the Realpage.dll component version 1.0.0.9. This ActiveX control is part of the broader RealPage Module ActiveX Controls suite, which facilitates file upload operations within web applications. The flaw manifests in the Upload method where the control fails to adequately validate or restrict property values, creating a potential security exposure that could be exploited by remote attackers. The vulnerability specifically affects the interaction between the SourceFile property and the DestURL property, which together enable malicious file access patterns.
The technical implementation of this vulnerability stems from insufficient input validation within the ActiveX control's property handling mechanism. When an attacker crafts a malicious request containing an http URL in the DestURL property alongside a filename in the SourceFile property, the control does not properly sanitize or validate these inputs. This lack of proper validation allows the control to process arbitrary file paths that could point to sensitive files on the target system. The vulnerability essentially enables a form of insecure file handling where the control treats user-supplied URLs and file paths as trusted inputs without adequate verification.
From an operational standpoint, this vulnerability presents a significant risk to systems running the affected RealPage Module ActiveX controls. Attackers could leverage this flaw to read arbitrary files from the target system, potentially accessing sensitive data, configuration files, or system resources that should remain protected. The remote exploitation capability means that an attacker does not need local system access to exploit this vulnerability, making it particularly dangerous in web environments where ActiveX controls are enabled. This type of vulnerability could lead to data breaches, system compromise, and unauthorized access to confidential information.
The 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. This classification indicates that the core issue involves inadequate restrictions on file path manipulation, allowing attackers to access files outside of intended directories. Additionally, this vulnerability maps to ATT&CK technique T1059.007, which covers command and scripting interpreter, as the exploitation could potentially lead to further command execution or privilege escalation. Organizations should implement strict input validation measures, disable unnecessary ActiveX controls, and ensure proper access controls are in place to prevent unauthorized file access. The recommended mitigation strategies include updating to patched versions of the RealPage controls, implementing network segmentation, and configuring appropriate firewall rules to restrict access to ActiveX-enabled applications.
