CVE-2025-25613: n/a
FS Inc S3150-8T2F 8-Port Gigabit Ethernet L2+ Switch, 8 x Gigabit RJ45, with 2 x 1Gb SFP, Fanless. All versions before 2.2.0D Build 135103 were discovered to transmit cookies for their web based administrative application containing usernames and passwords. These were transmitted in cleartext using simple base64 encoding during every POST request made to the server.
AI Analysis
Technical Summary
The FS Inc S3150-8T2F switch firmware versions prior to 2.2.0D Build 135103 expose a vulnerability (CVE-2025-25613) where cookies used by the web-based administrative interface contain usernames and passwords encoded only with base64 and transmitted in cleartext during POST requests. This constitutes a CWE-312 weakness (Cleartext Storage of Sensitive Information). The vulnerability allows remote attackers to capture sensitive credentials over the network without authentication. The CVSS v3.1 base score is 7.5, indicating high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and high confidentiality impact but no integrity or availability impact. The product is a cloud service, and a patch is available to remediate the issue.
Potential Impact
An unauthenticated remote attacker can intercept network traffic to capture administrative credentials transmitted in cleartext-encoded cookies, leading to potential unauthorized access to the device's administrative interface. This compromises confidentiality but does not affect integrity or availability.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade to firmware version 2.2.0D Build 135103 or later to mitigate the issue. Since this is a cloud service, the vendor manages remediation for the hosted service; verify with the vendor advisory for confirmation and deployment status.
