On Linksys E5350 WiFi Router with firmware version 1.0.00.037 and lower, (and potentially other vendors/devices due to code reuse), the /SysInfo.htm URI does not require a session ID. This web page calls a show_sysinfo function which retrieves WPA passwords, SSIDs, MAC Addresses, serial numbers, WPS Pins, and hardware/firmware versions, and prints this information into the web page. This web page is visible when remote management is enabled. A user who has access to the web interface of the device can extract these secrets. If the device has remote management enabled and is connected directly to the internet, this vulnerability is exploitable over the internet without interaction.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.5, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), for affected systems. Impacting 2 products from linksys, from linksys organizations running these solutions should prioritize assessment and patching.
Reported in 2022, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For linksys's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
