CVE-2008-5674 in webcamXP
Summary
by MITRE
Multiple array index errors in the HTTP server in Darkwet Network webcamXP 3.72.440.0 and earlier and beta 4.05.280 and earlier allow remote attackers to cause a denial of service (device crash) and read portions of memory via (1) an invalid camnum parameter to the pocketpc component and (2) an invalid id parameter to the show_gallery_pic component.

The vulnerability identified as CVE-2008-5674 represents a critical security flaw affecting Darkwet Network webcamXP versions 3.72.440.0 and earlier, as well as beta versions 4.05.280 and earlier. This issue manifests through multiple array index errors within the HTTP server component of the webcam software, creating significant operational risks for users who rely on these devices for surveillance and monitoring purposes. The vulnerability specifically impacts two distinct components of the webcamXP application, each presenting unique attack vectors that can be exploited by remote threat actors.
The technical implementation of this vulnerability stems from improper input validation within the HTTP server's handling of specific parameters. Attackers can exploit the vulnerability by sending malformed requests containing invalid camnum parameters to the pocketpc component and invalid id parameters to the show_gallery_pic component. These malformed inputs trigger array index errors that cause the application to access memory locations outside the intended array boundaries. Such memory access violations typically result in application crashes or device instability, leading to denial of service conditions that render the webcam system unusable. The underlying flaw falls under CWE-129, which specifically addresses insufficient validation of array indices, making this vulnerability particularly dangerous as it can be exploited without requiring authentication or specialized privileges.
The operational impact of CVE-2008-5674 extends beyond simple service disruption to potentially expose sensitive information through memory read operations. When the HTTP server processes malformed parameters, the array index errors can cause portions of the device's memory to be inadvertently read and returned in the server responses. This memory disclosure can potentially reveal sensitive data such as authentication credentials, system configuration details, or other confidential information stored in memory. The vulnerability affects devices that are often deployed in critical security environments where continuous operation is essential, making the denial of service aspect particularly concerning. Organizations relying on webcamXP for surveillance purposes face significant risks of operational disruption during attack scenarios, potentially leaving monitored areas unprotected.
Security professionals should prioritize immediate mitigation of this vulnerability through the application of available patches or updates from the vendor. The recommended approach involves upgrading to webcamXP versions that address the array index validation issues within the HTTP server components. Additionally, network segmentation and access control measures should be implemented to limit exposure of vulnerable webcam systems to untrusted networks. The vulnerability demonstrates the importance of proper input validation and boundary checking in web server implementations, aligning with ATT&CK technique T1499.004 which covers network denial of service attacks. Organizations should also consider implementing intrusion detection systems to monitor for suspicious parameter patterns that might indicate exploitation attempts, as the vulnerability can be leveraged for both service disruption and information disclosure purposes.
