Summary
by MITRE • 07/23/2021
Multiple buffer overflows in WebGate Control Center allow remote attackers to execute arbitrary code via unspecified vectors to the (1) GetRecFileInfo function in the FileConverter.FileConverterCtrl.1 control, (2) Login function in the LoginContoller.LoginControllerCtrl.1 control, or (3) GetThumbnail function in the WESPPlayback.WESPPlaybackCtrl.1 control.

The vulnerability identified as CVE-2015-2099 represents a critical security flaw within the WebGate Control Center software ecosystem, specifically targeting three distinct ActiveX controls that expose buffer overflow conditions. These buffer overflows occur in the FileConverter.FileConverterCtrl.1 control during the GetRecFileInfo function execution, the LoginContoller.LoginControllerCtrl.1 control during Login function processing, and the WESPPlayback.WESPPlaybackCtrl.1 control during GetThumbnail function operations. The flaw stems from insufficient input validation and memory management practices within these components, creating exploitable conditions that can be leveraged by remote attackers to gain unauthorized system access. The vulnerability classification aligns with CWE-121, which specifically addresses stack-based buffer overflow conditions, and CWE-122, covering heap-based buffer overflow scenarios that may occur in these ActiveX control implementations.
The technical exploitation of these buffer overflow conditions enables remote code execution capabilities through carefully crafted input data that exceeds the allocated buffer space in each vulnerable function. Attackers can manipulate the input parameters passed to these functions, causing memory corruption that allows arbitrary code execution with the privileges of the affected application. The attack surface is particularly concerning as these controls are designed for web-based interfaces, making them accessible through standard web browsers without requiring local system access. The vulnerability demonstrates characteristics consistent with the attack pattern described in ATT&CK technique T1059, specifically the execution of malicious code through compromised applications, and T1203, which involves the exploitation of vulnerabilities in software components to achieve unauthorized access.
The operational impact of this vulnerability extends beyond simple code execution, as successful exploitation can result in complete system compromise, data exfiltration, and persistent backdoor access to affected systems. Organizations utilizing WebGate Control Center software face significant risk exposure, particularly in environments where these ActiveX controls are deployed without proper security mitigations or network segmentation. The vulnerability affects systems that rely on these specific controls for file processing, user authentication, and media playback functionalities, potentially creating widespread impact across multiple operational domains. The lack of input sanitization in these components creates a persistent threat vector that remains active until proper patches or mitigations are implemented, making it particularly dangerous in environments where immediate remediation is not feasible.
Organizations should implement immediate mitigations including disabling ActiveX controls in web browsers, implementing network segmentation to isolate affected systems, and applying vendor-provided patches once available. The vulnerability highlights the importance of secure coding practices and input validation, particularly when developing components that interact with external data sources. Security teams should monitor for exploitation attempts through network traffic analysis and endpoint detection systems, as the buffer overflow conditions may generate specific patterns that can be detected through behavioral analysis. Additionally, regular security assessments should be conducted to identify other potentially vulnerable ActiveX controls or similar components within the organization's attack surface, as this vulnerability demonstrates the broader risk associated with legacy software components that lack proper memory management and input validation mechanisms.
