CVE-2007-5604 in Instant Support
Summary
by MITRE
Buffer overflow in the ExtractCab function in the HPISDataManagerLib.Datamgr ActiveX control in HPISDataManager.dll in HP Instant Support before 1.0.0.24 allows remote attackers to execute arbitrary code via a long first argument, a different vulnerability than CVE-2007-5605, CVE-2007-5606, and CVE-2007-5607.

The vulnerability identified as CVE-2007-5604 represents a critical buffer overflow condition within the HP Instant Support software suite, specifically affecting the HPISDataManagerLib.Datamgr ActiveX control. This flaw exists in the ExtractCab function of the HPISDataManager.dll component, which is part of HP Instant Support versions prior to 1.0.0.24. The vulnerability manifests when processing a malformed first argument parameter, creating an exploitable condition that can be leveraged by remote attackers to execute arbitrary code on affected systems. The flaw is distinct from other related vulnerabilities in the same vulnerability family including CVE-2007-5605, CVE-2007-5606, and CVE-2007-5607, each representing separate buffer overflow conditions within the same software component. The ActiveX control architecture creates a particularly dangerous attack surface since these components are designed to be executed within web browsers and other trusted environments, making them prime targets for exploitation.
The technical implementation of this buffer overflow vulnerability stems from inadequate bounds checking within the ExtractCab function. When the ActiveX control receives a first argument parameter that exceeds the allocated buffer size, the excess data overflows into adjacent memory regions, potentially overwriting critical program execution structures such as return addresses or function pointers. This memory corruption directly enables attackers to manipulate the program flow and execute malicious code with the privileges of the affected user. The vulnerability is classified under CWE-121 as a stack-based buffer overflow, where the insufficient input validation allows attackers to write beyond the bounds of allocated memory. The specific nature of the flaw suggests that the implementation does not properly validate the length of input parameters before processing them, creating a direct pathway for exploitation through malformed input data.
The operational impact of CVE-2007-5604 extends beyond simple code execution, as it provides attackers with a means to establish persistent access to vulnerable systems. Attackers can craft malicious web pages or download files that trigger the vulnerable ActiveX control, leading to remote code execution without requiring user interaction beyond visiting the malicious site. This vulnerability particularly affects enterprise environments where HP Instant Support is deployed, as it can be exploited through various attack vectors including drive-by downloads, malicious websites, or compromised email attachments. The exploitability of this vulnerability is enhanced by the fact that ActiveX controls are often enabled by default in Internet Explorer configurations, and many users may not be aware of the security implications of running such components. The vulnerability's classification under the ATT&CK framework aligns with techniques involving execution through compromised software components and privilege escalation through memory corruption exploits.
Mitigation strategies for CVE-2007-5604 should focus on immediate remediation through software updates and security configuration changes. The most effective solution involves upgrading to HP Instant Support version 1.0.0.24 or later, which contains patches addressing the buffer overflow condition in the affected ActiveX control. System administrators should also implement security measures such as disabling ActiveX controls in web browsers, particularly in environments where users do not require the functionality of such components. Additional protective measures include implementing application whitelisting policies to restrict execution of known vulnerable ActiveX controls, deploying network intrusion detection systems to monitor for exploitation attempts, and conducting regular security assessments to identify remaining vulnerable installations. Organizations should also consider removing or disabling HP Instant Support components if they are not essential for business operations, as this eliminates the attack surface entirely. The vulnerability highlights the importance of proper input validation and bounds checking in software development practices, particularly for components that are executed in untrusted environments such as web browsers.
