Detailed Analysis
-
Cross-Site Scripting (XSS)
By exploiting an XSS vulnerability an attacker may take over your login sessions and do anything your user account would be allowed to do. If they can lure an adminstrator into their trap, they would have access to all the data stored within Redmine, enabling them to read, change and delete everything. -
Persistent XSS in textile formattingHighSpecially crafted input in Redmine Textile text areas would allow an attacker to insert arbitrary Javascript which in turn was executed when any user opens an affected page, e.g. an issue, wiki page, etc.
-
Incomplete sanitization of multi-value custom fieldsHighAn attacker may use multi-value custom fields to embed malicious code into the issue history, the issue list, or the time log.Fixed in:
3.2.8,3.3.5,3.4.3More details: CVE-2017-15568, CVE-2017-15569, CVE-2017-15570, CVE-2017-15571 -
Cross-site scripting attack using manipulated SVG imagesHighAn attacker may attach malicious SVG images to issues or comments. When they are displayed to regular users, embeded code would be executed without their knowledge.
-
Incomplete sanitization of user supplied textModerateAn attacker may embed malicious code into issue descriptions or comments.
-
File Content Disclosure
By exploiting a File Content Disclosure vulnerability, attackers may be able to download certain files from your server. In severe cases, hackers could get access to any file they wish, including the files storing your Redmine database or server passwords. In consequence, they might be able to take over the entire server by logging in using a regular user's password. -
File Content Disclosure in Rails Action ViewHighSpecially crafted accept headers in combination with calls to certain URLs within Redmine can cause arbitrary files on the target server to be rendered, disclosing the file contents.
-
Remote Code Execution (RCE)
An RCE vulnerability allows attackers to run arbitrary code on your server. In consequence, this enables them to bypass all Redmine roles and permissions. They may read, change and delete all data stored in the Redmine database. Depending on the server configuration, they may even take over the entire server and do things like delete all backups or send out SPAM messages in your or your company's name. -
Remote Code Execution through Mercurial adapterHighOn Redmine installations with active Mercurial repositories, an attacker can take over the server and read and manipulate all data stored within your Redmine, possibly even take over the entire machine.
-
Denial of Service (DOS)
In a Denial of Service attack, your Redmine becomes compromised in a way that it does not function properly anymore. Using a Denial of Service vulnerability, attackers may not necessarily obtain or modify any data on the server, but they may render it unresponsive for users or disrupt certain functionality of your Redmine installation. -
Denial of Service Vulnerability in Rails Action ViewModerateSpecially crafted accept headers can cause the Action View template location code to consume 100% CPU, causing the Redmine server to be unable to process requests.
-
Reset tokens may leak to other websitesModerateSince the password reset tokens were part of the web address, users which follow links from the password reset page to other web sites, leak the token to these websites. It will appear in the log files of those external websites.
-
Information Leak
By exploiting an information leak, an attacker may see pieces of information, which would otherwise be hidden, effectively circumventing Redmine's roles an permissions. -
Missing permission check when access a repository via SVNModerateRedmine.pm lacks a check for whether the Repository module is enabled in a project's settings, which might allow remote attackers to obtain sensitive differences information or possibly have unspecified other impact.
-
Erroneous rendering of activity viewsModerateRedmine mishandles Time Entry rendering in activity views, which allows remote attackers to obtain sensitive information.
-
Erroneous rendering of wiki linksModerateRedmine mishandles the rendering of wiki links, which allows remote attackers to obtain sensitive information.
-
Reminder sent to ex-project membersLowReminder mails were sent to assignees, even if they no longer have access to the issue itself. This may reveal sensitive information.
