A file extension handling issue was found in [server] module of ONLYOFFICE DocumentServer v4.2.0.71-v5.6.0.21. The file extension is controlled by an attacker through the request data and leads to arbitrary file overwriting. Using this vulnerability, a remote attacker can obtain remote code execution on DocumentServer. Se encontró un problema de manejo de extensiones de archivo en el módulo [server] de ONLYOFFICE DocumentServer versiones v4.2.0.71-v5.6.0.21. La extensión del archivo está controlada por un atacante por medio de los datos de una petición y conlleva a una sobrescritura arbitraria del archivo. • https://github.com/ONLYOFFICE/DocumentServer https://github.com/ONLYOFFICE/server https://github.com/ONLYOFFICE/server/blob/v5.6.0.21/DocService/sources/converterservice.js#L200 https://github.com/ONLYOFFICE/server/blob/v5.6.0.21/FileConverter/sources/converter.js#L283 https://github.com/ONLYOFFICE/server/blob/v5.6.0.21/FileConverter/sources/converter.js#L593 https://github.com/merrychap/poc_exploits/tree/master/ONLYOFFICE/CVE-2021-25833 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
