CVE-2021-35956

30
FAUCET Score

CVE-2021-35956 describes a stored cross-site scripting (XSS) vulnerability in the embedded webserver of AKCP sensorProbe devices, including sensorProbe2, sensorProbe4, and sensorProbe8 models, prior to firmware version SP480-20210624. This medium-severity vulnerability (CVSS 5.4) allows authenticated attackers to inject arbitrary JavaScript by manipulating fields such as Sensor Description, Email settings, System Name, and System Location. Successful exploitation could lead to limited impact on confidentiality and integrity, requiring user interaction and network access. While not listed in CISA's KEV catalog or on the Hot List, an ExploitDB entry (EDB-50080) exists, indicating public exploit code availability, though there is minimal community discussion or media coverage.
