CVE-2007-2584 in VirusScan
Summary
by MITRE
Buffer overflow in the IsOldAppInstalled function in the McSubMgr.McSubMgr Subscription Manager ActiveX control (MCSUBMGR.DLL) in McAfee SecurityCenter before 6.0.25 and 7.x before 7.2.147 allows remote attackers to execute arbitrary code via a crafted argument.

The vulnerability identified as CVE-2007-2584 represents a critical buffer overflow flaw within McAfee SecurityCenter's subscription management ActiveX control. This issue specifically affects the IsOldAppInstalled function in the MCSUBMGR.DLL component, which operates as part of McAfee's security infrastructure. The vulnerability exists in versions prior to 6.0.25 and 7.x prior to 7.2.147, making it a significant concern for organizations running these older versions of the security suite. The flaw manifests when the ActiveX control processes a crafted argument, creating an exploitable condition that can be leveraged by remote attackers to gain unauthorized system access.
The technical implementation of this buffer overflow occurs within the IsOldAppInstalled function of the McSubMgr ActiveX control, which is designed to check for the presence of older applications. When an attacker supplies a maliciously crafted argument to this function, the control fails to properly validate the input length, leading to a buffer overrun condition. This type of vulnerability falls under CWE-121, which describes stack-based buffer overflow conditions where insufficient bounds checking allows attackers to overwrite adjacent memory locations. The ActiveX control's improper handling of user-supplied data creates a scenario where arbitrary code execution becomes possible through memory corruption techniques.
The operational impact of this vulnerability extends beyond simple code execution, as it enables attackers to potentially compromise entire systems through remote exploitation. The ActiveX control's integration with McAfee SecurityCenter means that successful exploitation could allow attackers to bypass security measures, modify system configurations, or establish persistent access points. This vulnerability is particularly dangerous because it operates within a security application itself, potentially undermining the very protection mechanisms designed to defend against such attacks. The remote nature of the exploit means that attackers do not require local system access, making the attack surface significantly broader than local privilege escalation vulnerabilities.
Organizations should implement immediate mitigation strategies to address this vulnerability, including updating to the patched versions of McAfee SecurityCenter. The recommended remediation involves upgrading to McAfee SecurityCenter 6.0.25 or 7.2.147, which contain the necessary fixes to prevent the buffer overflow condition. Additionally, administrators should consider implementing network segmentation and access controls to limit exposure, while monitoring for suspicious ActiveX control usage patterns. The vulnerability aligns with ATT&CK technique T1195.001, which covers the exploitation of ActiveX controls for privilege escalation and code execution. Security teams should also consider disabling or removing the vulnerable ActiveX control from systems where it is not essential for operations, as a temporary mitigation measure while planning for full patch deployment.
