Vulnerabilities

ONLYOFFICE Docs before 9.2.1 allows XSS via the Color theme name. This is related to DocumentServer.

Path Traversal vulnerability in ONLYOFFICE Document Server before v8.0.1 allows a remote attacker to copy arbitrary files by manipulating the fileExt parameter in the /example/editor endpoint, leading to unauthorized access to sensitive files and potential Denial of Service (DoS).

ONLYOFFICE Docs before 8.1.0 allows XSS via a GeneratorFunction Object attack against a macro. This is related to use of an immediately-invoked function expression (IIFE) for a macro. NOTE: this issue exists because of an incorrect fix for CVE-2021-43446 and CVE-2023-50883.

ONLYOFFICE Docs before 8.0.1 allows XSS because a macro is an immediately-invoked function expression (IIFE), and therefore a sandbox escape is possible by directly calling the constructor of the Function object. NOTE: this issue exists because of an incorrect fix for CVE-2021-43446.

An out of bounds memory access vulnerability in ONLYOFFICE DocumentServer 4.0.3 through 7.3.2 allows remote attackers to run arbitrary code via crafted JavaScript file.

Onlyoffice Community Server before v12.5.2 was discovered to contain a remote code execution (RCE) vulnerability via the component UploadProgress.ashx.

ONLYOFFICE Docs through 7.3 on certain Linux distributions allows local users to gain privileges via a Trojan horse libgcc_s.so.1 in the current working directory, which may be any directory in which an ONLYOFFICE document is located.

Given a malicious document provided by an attacker, the ONLYOFFICE Workspace DMS is vulnerable to a stored (persistent, or "Type II") cross-site scripting (XSS) condition.

ONLYOFFICE all versions as of 2021-11-08 is affected by Incorrect Access Control. An attacker can authenticate with the web socket service of the ONLYOFFICE document editor which is protected by JWT auth by using a default JWT signing key.

Onlyoffice Document Server v6.0.0 and below and Core 6.1.0.26 and below were discovered to contain a heap overflow via the component DesktopEditor/fontengine/fontconverter/FontFileBase.h.

A cross-site scripting (XSS) vulnerability in ONLYOFFICE Document Server Example before v7.0.0 allows remote attackers inject arbitrary HTML or JavaScript through /example/editor.

The Translate plugin 6.1.x through 6.3.x before 6.3.0.72 for ONLYOFFICE Document Server lacks escape calls for the msg.data and text fields.

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.

Directory traversal with remote code execution can occur in /upload in ONLYOFFICE Document Server before 5.6.3, when JWT is used, via a /.. sequence in an image upload parameter.

An issue was discovered in ONLYOFFICE Document Server 5.5.0. An attacker can craft a malicious .docx file, and exploit the unzip function to rewrite a binary and remotely execute code on a victim's server.
