Summary
MAGLINK LX Web Console versions 2.5.1 through 3.3 contain authentication bypass (CWE-288), broken authentication (CWE-305), and path traversal (CWE-22) vulnerabilities that allow unauthenticated remote attackers to gain full system access. Successful exploitation could allow modification of fueling system configurations, transaction records, and user accounts. Dover announced end-of-life for MAGLINK LX 3 in 2023 and released MAGLINK LX 4; the vulnerabilities are fixed in MAGLINK LX 3 version 3.4.2.2.6 and all MAGLINK LX 4 versions.
What this means
What could happen
An attacker could gain full administrative access to the MAGLINK LX console and modify fueling system configurations, potentially disrupting fuel delivery operations or redirecting transactions.
Who's at risk
Fuel retailers and convenience stores using Dover MAGLINK LX Console versions 2.5.1 through 3.3 for point-of-sale and pump management should prioritize remediation. This affects the fuel dispensing and transaction system that operators depend on for daily fueling operations and revenue collection.
How it could be exploited
An attacker with network access to the web console (port 80/443) can exploit authentication bypass and path traversal flaws to access the system without valid credentials. Once authenticated, the attacker can execute arbitrary operations such as changing system settings, user accounts, or transaction records.
Prerequisites
- Network access to MAGLINK LX Web Console (port 80/443)
- The console must be reachable from the attacker's network
- No valid credentials required
