A buffer overflow vulnerability exists in the ONVIF GetStreamUri function of LSC Indoor Camera V7.6.32. The application fails to validate the length of the Protocol parameter inside the Transport element. By sending a specially crafted SOAP request containing an oversized protocol string, an attacker can overflow the stack buffer, overwriting the return instruction pointer (RIP). This vulnerability allows for Denial of Service (DoS) via device crash or Remote Code Execution (RCE) in the context of the ONVIF service.
With a CVSS score of 7.2, this vulnerability is classified as high severity. It poses a significant risk to organizations utilizing the affected product, as it may lead to critical operational disruptions and potential unauthorized access to sensitive systems.
Risk to organizations includes the potential for device crashes and the ability for attackers to execute arbitrary code remotely, which could compromise the integrity and confidentiality of sensitive data. Organizations should prioritize patching immediately.
Currently, no public exploits or proof-of-concept (PoC) code is available for this vulnerability, but the lack of known exploitation does not diminish its immediate threat potential.
Vulnerability Details
The vulnerability is attributed to insufficient input validation within the ONVIF GetStreamUri function. Specifically, the application does not appropriately check the length of the Protocol parameter, which leads to a buffer overflow condition.
This flaw is characterized by two CWE classifications: CWE-20 (Improper Input Validation) and CWE-121 (Stack-based Buffer Overflow). The CVSS vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, indicating a network attack vector with low complexity but high privileges required for exploitation.
The vulnerability was published on March 27, 2026, and is marked as awaiting analysis, indicating that further details may still emerge as the situation evolves.
Technical Analysis
The root cause of this vulnerability is a failure to validate the length of the input parameter, which allows attackers to manipulate the application into executing unintended code. The attack vector is network-based, requiring no user interaction for the exploit to succeed.
The attack complexity is low, as it can be executed without any special conditions or prerequisites. The required privileges are high, indicating that an attacker would need to authenticate or have elevated permissions to exploit this vulnerability. However, the impacts on confidentiality, integrity, and availability are all rated as high, underscoring the severity of the potential outcomes.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant. Organizations utilizing the LSC Indoor Camera may face operational disruptions due to device crashes or unauthorized remote code execution. The blast radius could extend to critical infrastructure, putting sensitive data at risk.
In terms of urgency, organizations should prioritize addressing this vulnerability in their patch cycles, as the potential for exploitation exists despite the current absence of known exploits.
