CVE-2019-14310

Vulnerability

The vulnerability exists in the IPP service of Ricoh SP C250DN devices running firmware version 1.05. The embedded device does not properly parse crafted IPP packets, leading to memory corruption. No authentication is required to trigger the issue, and the attack vector is network-based via the IPP protocol.

Exploitation

An unauthenticated attacker can send specially crafted packets to the IPP service on the target device. The attacker only needs network access to the device; no user interaction or prior authentication is required. The memory corruption occurs during parsing of the malicious IPP packet, causing the device to crash.

Impact

Successful exploitation results in a denial of service (DoS) condition. The device crashes and becomes unavailable, disrupting printing and other services. There is no indication of information disclosure or remote code execution based on the available information [1].

Mitigation

The official vendor support page [1] does not provide a specific security update or workaround for this issue. Ricoh has not released a patched firmware version as of the publication date. Users should monitor Ricoh's support site for future updates and consider network-level filtering of IPP traffic as a temporary mitigation.
