On Reolink RLC-410W, C1 Pro, C2 Pro, RLC-422W, and RLC-511W devices through 1.0.227, an authenticated admin can use the "TestEmail" functionality to inject and run OS commands as root, as demonstrated by shell metacharacters in the addr1 field. This vulnerability allows attackers with administrative privileges to execute arbitrary commands on the device.
With a CVSS score of 7.2, this vulnerability is classified as high severity, indicating a significant risk to organizations utilizing these devices. The potential for exploitation is critical, given that it requires only an authenticated admin to execute malicious commands.
Risk to organizations includes the possibility of unauthorized access to sensitive information, system integrity compromise, and service disruption. The vulnerability's exploitation could lead to severe impacts on business operations and data security.
Organizations should prioritize patching immediately. With the vulnerability being actively tracked and included in the Known Exploited Vulnerabilities (KEV) catalog, it is crucial for defenders to take swift action to mitigate associated risks.
The vulnerability was published on April 8, 2019, and remains relevant as of the latest update in November 2025. Organizations using the affected Reolink products must address this vulnerability to avoid potential exploitation.
Vulnerability Details
This vulnerability allows authenticated users to exploit the "TestEmail" functionality of various Reolink IP camera models to execute OS commands with root privileges. The CVSS 3.1 score of 7.2 indicates high risk, highlighting the critical need for immediate attention.
The affected devices include Reolink RLC-410W, C1 Pro, C2 Pro, RLC-422W, and RLC-511W with firmware versions up to 1.0.227. The vulnerability is classified under CWE-78, which pertains to OS command injection.
Technical Analysis
The root cause of this vulnerability lies in insufficient input validation within the "TestEmail" feature, allowing the injection of arbitrary shell commands. The attack vector is network-based, requiring high privileges to exploit.
Attack complexity is low, as an authenticated user can exploit this vulnerability with no user interaction required. The impacts of such exploitation include high confidentiality, integrity, and availability risks.
Risk & Impact Analysis
Organizations face significant deployment risks due to this vulnerability. The potential blast radius is extensive, as multiple camera models are affected, leading to widespread security concerns if exploited.
The urgency for remediation is critical, particularly given the CVSS score and the inclusion in the KEV catalog. Failure to address this vulnerability could result in unauthorized access and severe operational disruption.
