02 Description

Tycon Systems TPDIN-Monitor-WEB2 Cleartext Storage of Sensitive Information

03 Exploitation and scoring

Exploitation

Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.

SSVC decision

ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.

EPSS probability

0.19% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 9.2% of scored records. A rank, not a probability.

NVD base score

5.3 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

Tycon Systems has released firmware 2.4.5, which resolves this vulnerability by removing cleartext credentials from the web interface response. Further inquiries can be directed to security@tyconsystems.com. Tycon Systems recommends changing any factory-default SNMP community strings and the Telnet password if they were left at shipped values. Leave Telnet disabled unless required. Tycon Systems recommends using a dedicated mail account for device alerts, rather than an account also used for other sensitive purposes, to limit exposure if credentials are compromised.
