Because of this, a user with permission to modify data could upload a file containing a local file path or a web address instead.\n\nIf a local file path was supplied, MISP could read that file from the server. If a URL was supplied, MISP could make a request to that address, including systems that may only be reachable from inside the organization’s network.\n\nThe vulnerability could therefore expose sensitive local files and allow unauthorized requests to internal services.\n\nExploitation required a valid MISP account with modify permissions, but no additional user interaction was needed.\n\nVersion affected: <2.5.47\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":46,"depthScoreParts":{"impact":45.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
