CVE-2014-1201 in Edge2 Lh330
Summary
by MITRE
Buffer overflow in the INetViewX ActiveX control in the Lorex Edge LH310 and Edge+ LH320 series with firmware 7-35-28-1B26E, Edge2 LH330 series with firmware 11.17.38-33_1D97A, and Edge3 LH340 series with firmware 11.19.85_1FE3A allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string in the HTTP_PORT parameter.

The vulnerability identified as CVE-2014-1201 represents a critical buffer overflow flaw within the INetViewX ActiveX control deployed in Lorex security camera systems. This vulnerability specifically affects the Edge LH310, Edge+ LH320, Edge2 LH330, and Edge3 LH340 series devices operating with the listed firmware versions. The flaw resides in how the ActiveX control processes the HTTP_PORT parameter, creating an exploitable condition that can be leveraged by remote attackers to compromise system integrity. The vulnerability stems from inadequate input validation and bounds checking within the control's memory management mechanisms, allowing maliciously crafted input to overwrite adjacent memory locations.
The technical implementation of this buffer overflow occurs when an attacker submits an excessively long string value through the HTTP_PORT parameter in network requests targeting these devices. The INetViewX control fails to properly validate the length of input data before processing, leading to memory corruption that manifests as program termination or arbitrary code execution. This vulnerability directly maps to CWE-121, which describes stack-based buffer overflow conditions, and CWE-122, which addresses heap-based buffer overflow scenarios. The control's improper handling of user-supplied input creates a pathway for attackers to manipulate memory layout and potentially gain unauthorized system access. The flaw's remote exploitability means that adversaries need not have physical access to the devices, making the vulnerability particularly dangerous in networked environments.
The operational impact of this vulnerability extends beyond simple denial of service conditions to potentially enable complete system compromise. When exploited successfully, the buffer overflow can cause devices to crash and restart, creating availability issues that may disrupt surveillance operations. More critically, the vulnerability's potential for arbitrary code execution means that attackers could install malicious software, modify system configurations, or gain persistent access to the affected devices. This represents a significant risk for security infrastructure, as these devices often serve as critical components in enterprise and residential security systems. The vulnerability affects both the availability and integrity aspects of the security infrastructure, potentially allowing attackers to bypass security measures or establish backdoors within networked environments. Organizations relying on these devices for surveillance may face unauthorized access to sensitive footage and system control, with implications for privacy and security compliance.
Mitigation strategies for CVE-2014-1201 should prioritize immediate firmware updates from Lorex, as this represents the most effective defense against the vulnerability. Network administrators should implement perimeter security measures including firewalls and intrusion detection systems to monitor for suspicious HTTP_PORT parameter usage and limit access to affected devices. The principle of least privilege should be enforced by restricting network access to these devices to only authorized personnel and systems. Additionally, organizations should consider network segmentation to isolate affected devices from critical infrastructure and implement regular vulnerability assessments to identify similar flaws in other ActiveX controls or legacy systems. Security monitoring should include detection of anomalous parameter values in HTTP requests and regular system integrity checks to identify potential exploitation attempts. The ATT&CK framework categorizes this vulnerability under T1203, which covers exploitation for execution, and T1071, which addresses application layer protocols, making it a significant concern for enterprise security teams implementing comprehensive threat detection strategies.
