A reflected cross-site scripting (XSS) vulnerability in the /logo.asp component of FS Inc S3150-8T2F Switch 2.2.0D Build 118101 allows attackers to execute arbitrary Javascript in the context of the victim's browser via a crafted URL.
AnalysisAI
Reflected cross-site scripting in the FS Inc S3150-8T2F Switch web management interface allows remote unauthenticated attackers to execute arbitrary JavaScript in an authenticated administrator's browser by tricking them into clicking a crafted URL targeting the /logo.asp endpoint. The vulnerability carries a CVSS 6.1 score with changed scope, enabling session hijacking, credential theft, or unauthorized device reconfiguration through the victim's browser session. No public exploit code has been confirmed and EPSS sits at 0.14% (4th percentile), indicating negligible observed exploitation probability at time of analysis.
Technical ContextAI
CWE-79 (Improper Neutralization of Input During Web Page Generation) describes the root cause: user-supplied input is reflected into the HTTP response without adequate sanitization or output encoding. The vulnerable component is /logo.asp, a page in the switch's embedded web management interface running firmware version 2.2.0D Build 118101. The changed scope (S:C in the CVSS vector) reflects the XSS executing in the victim's browser rather than the server - a textbook reflected XSS scenario. The CPE data supplied (cpe:2.3:a:n/a:n/a) is uninformative and vendor-specific CPE strings were not provided by NVD or EUVD. The affected product is the FS Inc S3150-8T2F, an 8-port 10G switch with 2x 25G SFP28 uplinks, typically deployed in small enterprise or SMB edge network environments. The web management UI is the attack surface, suggesting the vulnerability exists in the switch's embedded HTTP server.
RemediationAI
No vendor-released patch has been identified at time of analysis; no FS Inc security advisory was found in the referenced sources. As an immediate compensating control, restrict access to the switch's web management interface to trusted management VLANs or dedicated jump hosts only - blocking general network access to the management UI eliminates the reflected XSS attack surface entirely, though it removes the convenience of browser-based management. Additionally, enforce the use of HTTPS for the management interface if supported, which does not prevent XSS but reduces session interception risk. Train network administrators to treat any unsolicited links purporting to point to switch management interfaces as suspicious. Monitor the VulDB entry at https://vuldb.com/vuln/385151 and the researcher's disclosure at https://github.com/whitewhale-dmb/Vulnerability-Research/tree/main/CVE-2026-52232 for any vendor patch release. Using the switch CLI or SNMP for management tasks instead of the web UI entirely avoids the vulnerable component.
