CVE-2008-0437: HP Virtual Rooms ActiveX Control Buffer Overflow
Hp · Virtual Rooms
The WebHPVCInstall.HPVirtualRooms14 ActiveX control in HPVirtualRooms14.dll 1.0.0.100 contains multiple buffer overflows in the AuthenticationURL, PortalAPIURL, and cabroot properties. A remote attacker can supply oversized values to these properties to corrupt memory and execute arbitrary code in the context of the user who loads the control.
Description
Multiple buffer overflows in the WebHPVCInstall.HPVirtualRooms14 ActiveX control in HPVirtualRooms14.dll 1.0.0.100, as used in the installation process for HP Virtual Rooms, allow remote attackers to execute arbitrary code via a long (1) AuthenticationURL, (2) PortalAPIURL, or (3) cabroot property value. NOTE: some of these details are obtained from third party information.
AV:N/AC:L/Au:N/C:C/I:C/A:C
Automated analysis
high priorityThe CVSS 2.0 score is 10.0 with network reachability and no authentication, and public exploit code exists, though the product is legacy and no KEV listing is present.
What it is
The WebHPVCInstall.HPVirtualRooms14 ActiveX control in HPVirtualRooms14.dll 1.0.0.100 contains multiple buffer overflows in the AuthenticationURL, PortalAPIURL, and cabroot properties. A remote attacker can supply oversized values to these properties to corrupt memory and execute arbitrary code in the context of the user who loads the control.
Impact
Successful exploitation gives the attacker arbitrary code execution with the privileges of the user running the ActiveX control, potentially leading to full system compromise. Because the control is used during HP Virtual Rooms installation, the attacker gains a foothold on the victim's machine.
Attack surface
The flaw is reached over the network through the ActiveX control, which is instantiated in a browser or installation context. No authentication is required per the CVSS vector (AV:N/AC:L/Au:N), but the victim must load or interact with the malicious page or content that invokes the control.
Exploitation
The record is not listed in CISA KEV, but EPSS is high (0.5808, 99th percentile) and a public Exploit-DB entry (4959) exists, indicating exploit code is available. No ransomware associations are documented.
What to do
- Apply the vendor patch or update for HP Virtual Rooms / HPVirtualRooms14.dll if still supported; if no patch is available, remove or disable the affected ActiveX control.
- Set the kill bit for the WebHPVCInstall.HPVirtualRooms14 CLSID in Internet Explorer to prevent the control from loading.
- Restrict browser use of ActiveX controls and enforce allow-listing so only trusted, signed controls can run.
- Block or monitor network delivery of the control and related installation content at the perimeter.
- Migrate users off legacy ActiveX-dependent HP Virtual Rooms components where possible.
Detection
- Search endpoint and browser logs for instantiation of the WebHPVCInstall.HPVirtualRooms14 CLSID or loading of HPVirtualRooms14.dll.
- Monitor for suspicious child processes spawned by browser or installer processes that load the control.
- Use file integrity monitoring to detect unexpected changes to HPVirtualRooms14.dll or its registration.
- Review proxy and DNS logs for requests to known exploit or malicious hosting URLs associated with this control.
