{"id":"GHSA-29w6-c52g-m8jc","summary":"C5 Firefly III CSV Injection.","details":"### Summary\nCSV injection is a vulnerability where untrusted user input in CSV files can lead to unauthorized access or data manipulation. \nIn my subsequent testing of the application.\n\n### Details\nI discovered that there is an option to \"Export Data\" from the web app to your personal computer, which exports a \"csv\" file that can be opened with Excel software that supports macros.\n\nP.S \nI discovered that the web application's is offering a demo-site that anyone may access to play with the web application. So, there's a chance that someone will export the data (CVS) from the demo site and execute it on their PC, giving the malicious actor a complete control over their machine. (if a user enters a malicious payload to the website).\n\n### PoC\nYou can check out my vulnerability report if you need more details/PoC with screenshots: (removed by JC5)\n\n### Impact\nAn attacker can exploit this by entering a specially crafted payload to one of the fields, and when a user export the csv file using the \"Export Data\" function, the attacker can potentiality can RCE.\n\n### Addendum by JC5, the developer of Firefly III\nThere is zero impact on normal users, even on vulnerable versions.","modified":"2024-12-06T05:33:33.243312Z","published":"2024-01-31T18:05:46Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2024-01-31T18:05:46Z","nvd_published_at":null,"cwe_ids":[],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/firefly-iii/firefly-iii/security/advisories/GHSA-29w6-c52g-m8jc"},{"type":"PACKAGE","url":"https://github.com/firefly-iii/firefly-iii"}],"affected":[{"package":{"name":"grumpydictator/firefly-iii","ecosystem":"Packagist","purl":"pkg:composer/grumpydictator/firefly-iii"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.7"}]}],"versions":["3.0.0","3.0.1","3.0.2","3.0.3","3.1","3.1.1","3.1.2","3.1.3","3.1.4","3.1.5","3.1.6","3.10","3.10.1","3.10.2","3.10.3","3.10.4","3.2.0","3.2.1","3.2.2","3.2.3","3.2.4","3.2.5","3.3","3.3.1","3.3.2","3.3.3","3.3.4","3.3.5","3.3.6","3.3.7","3.3.8","3.3.9","3.4","3.4.0.1","3.4.0.10","3.4.0.2","3.4.0.3","3.4.0.4","3.4.0.5","3.4.0.6","3.4.0.7","3.4.0.8","3.4.0.9","3.4.1","3.4.10","3.4.11","3.4.2","3.4.3","3.4.4","3.4.4.1","3.4.4.2","3.4.5","3.4.6","3.4.6.1","3.4.7","3.4.8","3.4.9","3.5.0","3.5.1","3.5.2","3.5.3","3.5.4","3.5.5","3.5.6","3.5.6.1","3.6.0","3.6.1","3.7.0","3.7.1","3.7.2","3.7.2.1","3.7.2.2","3.7.2.3","3.8.0","3.8.1","3.8.2","3.8.3","3.8.4","3.9.0","3.9.1","4.0.0","4.0.1","4.0.2","4.1.0","4.1.1","4.1.2","4.1.3","4.1.4","4.1.5","4.1.6","4.1.7","4.2.0","4.2.1","4.2.2","4.3.0","4.3.1","4.3.2","4.3.3","4.3.4","4.3.5","4.3.6","4.3.7","4.3.8","4.4.0","4.4.1","4.4.2","4.4.3","4.5.0","4.6.0","4.6.1","4.6.10","4.6.11","4.6.11.1","4.6.12","4.6.13","4.6.2","4.6.3","4.6.3.1","4.6.4","4.6.5","4.6.6","4.6.7","4.6.8","4.6.9","4.7.0","4.7.1","4.7.1.1","4.7.1.2","4.7.1.3","4.7.1.4","4.7.10","4.7.11","4.7.12","4.7.12.1","4.7.13","4.7.14","4.7.15","4.7.16","4.7.17","4.7.17.1","4.7.17.2","4.7.17.3","4.7.17.4","4.7.17.5","4.7.17.6","4.7.2","4.7.2.1","4.7.2.2","4.7.3","4.7.3.1","4.7.3.2","4.7.4","4.7.5","4.7.5.1","4.7.5.2","4.7.5.3","4.7.6","4.7.6.1","4.7.6.2","4.7.7","4.7.8","4.7.9","4.8.0","4.8.0.1","4.8.0.2","4.8.0.3","4.8.1","4.8.1.1","4.8.1.2","4.8.1.3","4.8.1.4","4.8.1.5","4.8.1.6","4.8.1.7","4.8.1.8","4.8.2","4.8.2-alpha.1","4.8.2-alpha.2","4.8.2-alpha.3","4.8.2-alpha.4","4.8.2-alpha.5","4.8.2-alpha.6","4.8.2-beta.1","4.8.2-beta.2","4.8.3-alpha.1","5.0.0","5.0.0-alpha.1","5.0.0-alpha.2","5.0.0-beta.1","5.0.1","5.0.2","5.0.3","5.0.4","5.0.5","5.1.0","5.1.0-alpha.1","5.1.0-beta.1","5.1.1","5.2.0","5.2.0-alpha.1","5.2.0-beta.1","5.2.1","5.2.2","5.2.3","5.2.4","5.2.5","5.2.6","5.2.7","5.2.8","5.3.0","5.3.0-alpha.1","5.3.0-beta.1","5.3.0-beta.2","5.3.1","5.3.2","5.3.3","5.4.0","5.4.0-alpha.1","5.4.0-alpha.2","5.4.0-alpha.3","5.4.0-beta.1","5.4.1","5.4.2","5.4.3","5.4.4","5.4.5","5.4.6","5.5.0","5.5.0-beta.1","5.5.0-beta.2","5.5.0-beta.3","5.5.1","5.5.10","5.5.11","5.5.12","5.5.13","5.5.2","5.5.3","5.5.4","5.5.5","5.5.6","5.5.7","5.5.8","5.5.9","5.6.0","5.6.0-alpha.1","5.6.0-alpha.2","5.6.1","5.6.10","5.6.11","5.6.12","5.6.13","5.6.14","5.6.15","5.6.16","5.6.2","5.6.3","5.6.4","5.6.5","5.6.6","5.6.7","5.6.8","5.6.9","5.7.0","5.7.1","5.7.10","5.7.11","5.7.12","5.7.13","5.7.14","5.7.15","5.7.16","5.7.17","5.7.18","5.7.2","5.7.3","5.7.4","5.7.5","5.7.6","5.7.7","5.7.8","5.7.9","5.8.0-alpha.1","6.0.0-alpha.1","6.0.0-alpha.2","6.0.0-beta.1","6.0.9","v6.0.0","v6.0.0-beta.2","v6.0.1","v6.0.10","v6.0.11","v6.0.12","v6.0.13","v6.0.14","v6.0.15","v6.0.16","v6.0.17","v6.0.18","v6.0.19","v6.0.2","v6.0.20","v6.0.21","v6.0.22","v6.0.23","v6.0.24","v6.0.25","v6.0.26","v6.0.27","v6.0.28","v6.0.29","v6.0.3","v6.0.30","v6.0.4","v6.0.5","v6.0.6","v6.0.7","v6.0.8","v6.1.0","v6.1.0-alpha.1","v6.1.1","v6.1.2","v6.1.3","v6.1.4","v6.1.5","v6.1.6"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-29w6-c52g-m8jc/GHSA-29w6-c52g-m8jc.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:L"}]}
