DescriptionCVE.org

An attacker with access via network to the Regesta Smart HD-PLC of the provider Teldat (in this case, NO registration action is required) who has the vulnerable software could, with a Slow Loris attack, cause Denial of Service (DoS) on the web interface of the device. This issue affects Regesta Smart HD-PLC - TLDPH16D2: 11.02.05.10.02.

AnalysisAI

The web management interface of the Teldat Regesta Smart HD-PLC (model TLDPH16D2, firmware 11.02.05.10.02) is susceptible to resource exhaustion via a Slow Loris attack, making the administrative interface unavailable to legitimate operators. An unauthenticated network attacker can trigger this condition without any prior registration or credentials, as the embedded web server imposes no connection-hold limits or timeouts per CWE-770. …

Vulnerability AssessmentAI

Exploitation The attack requires network reachability to the Teldat Regesta Smart HD-PLC TLDPH16D2 web management interface (typically TCP port 80 or 443) running firmware version 11.02.05.10.02. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 6.9 correctly captures a network-reachable, unauthenticated, low-complexity DoS with limited availability impact (VA:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker with network access to the device's HTTP web interface uses a readily available Slow Loris tool to open hundreds of partial HTTP connections, each drip-feeding incomplete request headers at slow intervals to prevent server-side timeout. Within seconds to minutes the embedded web server exhausts its connection pool, rendering the management interface unresponsive to any further legitimate administrator sessions. …
Remediation Apply the vendor-released patch available through the Teldat customer support portal at https://support.teldat.com/portal/supportcontent?page=cgs-customer-global-support&none=true&language=en-US. … Detailed patch versions, workarounds, and compensating controls in full report.
