Fuji Electric V-Server 4.0.3.0 and prior, Multiple untrusted pointer dereference vulnerabilities have been identified, which may allow remote code execution.

Weakness

The product obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer.

Affected Software

Name Vendor Start Version End Version
V-server_firmware Fujielectric * 4.0.3.0 (including)

Extended Description

An attacker can supply a pointer for memory locations that the product is not expecting. If the pointer is dereferenced for a write operation, the attack might allow modification of critical state variables, cause a crash, or execute code. If the dereferencing operation is for a read, then the attack might allow reading of sensitive data, cause a crash, or set a variable to an unexpected value (since the value will be read from an unexpected memory location). There are several variants of this weakness, including but not necessarily limited to:
