ONLYOFFICE/DocumentServer

ONLYOFFICE DocumentServer before 9.3.0 has an untrusted pointer dereference in XLS processing/conversion (via pictFmla.cbBufInCtlStm and other vectors), leading to an information leak and ASLR bypass.

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

ONLYOFFICE Docs before 9.2.1 allows XSS via the Font field for the Multilevel list settings window. This is related to DocumentServer.

ONLYOFFICE Docs before 9.2.1 allows XSS in the textarea of the comment editing form. This is related to DocumentServer.

ONLYOFFICE Docs (DocumentServer) in versions equal and below 8.3.1 are affected by a reflected cross-site scripting (XSS) issue when opening files via the WOPI protocol. Attackers could inject malicious scripts via crafted HTTP POST requests, which are then reflected in the server's HTML response.

Memory Exhaustion vulnerability in ONLYOFFICE Document Server 4.0.3 through 7.3.2 allows remote attackers to cause a denial of service via crafted JavaScript file.

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.

A use after free issue discovered in ONLYOFFICE DocumentServer 4.0.3 through 7.3.2 allows remote attackers to run arbitrary code via crafted JavaScript file.

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 Document Server v6.0.0 and below and Core 6.1.0.26 and below were discovered to contain a stack overflow via the component DesktopEditor/common/File.cpp.

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.

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.

A heap buffer overflow vulnerability inside of BMP image processing was found at [core] module of ONLYOFFICE DocumentServer v4.0.0-9-v6.0.0. Using this vulnerability, an attacker is able to gain remote code executions on DocumentServer.

A file extension handling issue was found in [core] module of ONLYOFFICE DocumentServer v4.0.0-9-v5.6.3. An attacker must request the conversion of the crafted file from PPTT into PPTX format. Using the chain of two other bugs related to improper string handling, a remote attacker can obtain remote code execution on DocumentServer.

A file extension handling issue was found in [core] module of ONLYOFFICE DocumentServer v4.2.0.236-v5.6.4.13. An attacker must request the conversion of the crafted file from DOCT into DOCX format. Using the chain of two other bugs related to improper string handling, an attacker can achieve remote code execution on DocumentServer.

An improper binary stream data handling issue was found in the [core] module of ONLYOFFICE DocumentServer v4.0.0-9-v5.6.3. Using this bug, an attacker is able to produce a denial of service attack that can eventually shut down the target server.

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 NSFileDownloader function to pass parameters to a binary (such as curl or wget) and remotely execute code on a victim's server.

A SQL Injection issue was discovered in ONLYOFFICE Document Server 5.5.0. An attacker can execute arbitrary SQL queries via injection to DocID parameter of Websocket API.

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.

An issue was discovered in ONLYOFFICE Document Server 5.5.0. An attacker can craft a malicious .docx file, and exploit XML injection to enter an attacker-controlled parameter into the x2t binary, to rewrite this binary and/or libxcb.so.1, and execute code on a victim's server.
