CVE-2007-2955 in AntiVirus
Summary
by MITRE
Multiple unspecified "input validation error" vulnerabilities in multiple ActiveX controls in NavComUI.dll, as used in multiple Norton AntiVirus, Internet Security, and System Works products for 2006, allows remote attackers to execute arbitrary code via (1) the AnomalyList property to AxSysListView32 and (2) Anomaly property to AxSysListView32OAA.

The vulnerability identified as CVE-2007-2955 represents a critical security flaw affecting multiple Norton security products from 2006, specifically targeting ActiveX controls embedded in the NavComUI.dll library. This issue manifests as unspecified input validation errors within the ActiveX components that form part of the Norton AntiVirus, Internet Security, and System Works suites, creating a significant attack surface for remote code execution. The vulnerability is particularly concerning because it affects components that are integral to the security software's operation, potentially allowing attackers to compromise systems that are specifically designed to protect against such threats.
The technical exploitation of this vulnerability occurs through two distinct attack vectors targeting the AxSysListView32 ActiveX control and its associated AnomalyList property, as well as the AxSysListView32OAA control with its Anomaly property. These input validation errors occur when the ActiveX controls fail to properly validate user-supplied data before processing it, creating opportunities for buffer overflows or other memory corruption conditions. The flaw essentially allows attackers to craft malicious input that, when processed by the vulnerable ActiveX controls, can trigger arbitrary code execution within the context of the user's privileges. This represents a classic input validation vulnerability that falls under CWE-20, which encompasses input validation errors that can lead to various security issues including code execution.
The operational impact of CVE-2007-2955 is substantial, as it enables remote attackers to execute arbitrary code on vulnerable systems without requiring authentication or elevated privileges. Attackers can leverage this vulnerability through web browsers or other applications that load the vulnerable ActiveX controls, making it particularly dangerous in enterprise environments where users may browse untrusted websites or open malicious attachments. The vulnerability creates a persistent threat vector that could allow attackers to install malware, modify system files, or establish backdoors, effectively undermining the security posture that Norton products are designed to provide. This creates a paradoxical situation where security software becomes a potential attack vector rather than a protective measure.
Mitigation strategies for this vulnerability should focus on immediate remediation through official security patches provided by Symantec, as well as network-level protections such as ActiveX control restrictions and browser security settings that prevent loading of vulnerable components. Organizations should implement strict patch management procedures to ensure all affected Norton products are updated promptly. Additionally, security professionals should consider implementing network segmentation and monitoring to detect potential exploitation attempts, while also reviewing and restricting ActiveX control usage in corporate environments. The vulnerability aligns with ATT&CK technique T1203, which covers exploitation of remote services, and demonstrates the importance of maintaining up-to-date security software and the inherent risks associated with legacy ActiveX controls in modern security architectures.
