Summary
CSL DualCom GPRS CS2300-R devices with firmware 1.25 through 3.53 rely on a polyalphabetic substitution cipher with hardcoded keys, which makes it easier for remote attackers to defeat a cryptographic protection mechanism by capturing IP or V.22bis PSTN protocol traffic.
Exploit prediction
2.12% chance of exploitation in the next 30 days, higher than 81% of all scored CVEs (FIRST EPSS, 2026-11-09).
