Description
A vulnerability was determined in mifi lossless-cut up to 3.69.0. Affected by this issue is some unknown functionality of the file src/main/httpServer.ts of the component Built-in HTTP API Service. Executing a manipulation can lead to server-side request forgery. The attack requires access to the local network. This attack is characterized by high complexity. The exploitation is known to be difficult. The exploit has been publicly disclosed and may be utilized. This patch is called 260802348955231442c4bae6c2d9d8ede947af0a. It is best practice to apply a patch to resolve this issue. The project maintainer provides this view: "I'm not sure that this is a critical vulnerability, because it is behind an experimental CLI flag and the NTLM behavior isn't really a LosslessCut bug." The CVSS vector reflects the high level of pre-requisites.
Public exploit
An exploit or proof of concept is public: anyone can try it against an unpatched system. A reference of the record is tagged as an exploit. CISA's SSVC rates its exploitation: a proof of concept is public.
