CVE-2007-2323 in Home Theater
Summary
by MITRE
Multiple buffer overflows in the WinDVDX ActiveX control in InterVideo Home Theater 2.1.13.0 and 2.5.13.58 allow remote attackers to execute arbitrary code via a long string argument to the (1) GetDiscType or (2) AddFileList method.

The vulnerability identified as CVE-2007-2323 represents a critical security flaw in the WinDVDX ActiveX control component of InterVideo Home Theater software versions 2.1.13.0 and 2.5.13.58. This vulnerability manifests as multiple buffer overflow conditions that occur when processing user-supplied input through specific method calls within the ActiveX control interface. The affected methods include GetDiscType and AddFileList, which are exposed to remote attackers through web-based attack vectors. Buffer overflows in ActiveX controls are particularly dangerous because they can be triggered through web browsers when users visit compromised websites or click on malicious links, making this vulnerability exploitable in widespread attack scenarios.
The technical nature of this flaw stems from improper input validation and memory management within the WinDVDX ActiveX control implementation. When the GetDiscType or AddFileList methods receive excessively long string arguments, the control fails to properly bounds-check the input data before copying it into fixed-size buffers. This lack of proper input sanitization creates opportunities for attackers to overwrite adjacent memory locations, potentially leading to arbitrary code execution with the privileges of the user running the vulnerable software. The vulnerability falls under CWE-121, which specifically addresses stack-based buffer overflow conditions, and CWE-122, which covers heap-based buffer overflow scenarios that may occur in similar ActiveX control implementations.
The operational impact of CVE-2007-2323 extends beyond simple code execution capabilities to encompass broader system compromise potential. Attackers exploiting this vulnerability can gain complete control over affected systems, potentially installing backdoors, stealing sensitive data, or using the compromised machines as launching points for further attacks within network environments. The vulnerability affects Windows operating systems running the vulnerable InterVideo Home Theater software, making it particularly concerning for enterprise environments where multimedia applications are commonly installed. The attack surface is significantly broadened due to the ActiveX control's integration with web browsers, allowing attackers to exploit this vulnerability through web-based attack vectors without requiring local system access or user interaction beyond visiting a malicious website.
Mitigation strategies for this vulnerability should focus on immediate remediation through software updates from InterVideo, as well as network-level protections to prevent exploitation. System administrators should implement browser security configurations that disable ActiveX controls or restrict their execution to trusted sites only. The vulnerability demonstrates the importance of proper input validation and memory safety practices in software development, aligning with ATT&CK technique T1059.007 for command and scripting interpreter execution. Organizations should also consider implementing application whitelisting policies to prevent execution of untrusted ActiveX controls and maintain updated vulnerability management processes to identify and remediate similar issues in other multimedia and media player software components.
