Dotcms

A sandbox escape vulnerability exists in dotCMS’s Velocity scripting engine (VTools) that allows authenticated users with scripting privileges to bypass class and package restrictions enforced by SecureUberspectorImpl. By dynamically modifying the Velocity engine’s runtime configuration and reinitializing its Uberspect, a malicious actor can remove the introspector.restrict.classes and introspector.restrict.packages protections. Once these restrictions are cleared, the attacker can access arbitrary Java classes, including java.lang.Runtime, and execute arbitrary system commands under the privileges of the application process (e.g. dotCMS or Tomcat user).Show less

The "reset password" login page accepted an HTML injection via URL parameters. This has already been rectified via patch, and as such it cannot be demonstrated via Demo site link. Those interested to see the vulnerability may spin up a http://localhost:8082/dotAdmin/#/public/login?resetEmailSent=true&resetEmail=%3Ch1%3E%3Ca%20href%3D%22https:%2F%2Fgoogle.com%22%3ECLICK%20ME%3C%2Fa%3E%3C%2Fh1%3E This will result in a view along these lines: * OWASP Top 10 - A03: Injection * CVSS Score: 5.4 * AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator * https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N&... https://nvd.nist.gov/vuln-metrics/cvss/v3-calculatorShow less

System->Maintenance-> Log Files in dotCMS dashboard is providing the username/password for database connections in the log output. Nevertheless, this is a moderate issue as it requires a backend admin as well as that dbs are locked down by environment.   OWASP Top 10 - A05) Insecure Design OWASP Top 10 - A05) Security Misconfiguration OWASP Top 10 - A09) Security Logging and Monitoring FailureShow less

In dotCMS dashboard, the Tools and Log Files tabs under System → Maintenance Portlet, which is and always has been an Admin portlet, is accessible to anyone with that portlet and not just to CMS Admins. Users that get site admin but not a system admin, should not have access to the System Maintenance → Tools portlet. This would share database username and password under Log Files and download DB Dump and other dotCMS Content under Tools. Nothing in the System → Maintenance should be displayed for users with site admin role. Only system admins must have access to System Maintenance.

In dotCMS, versions mentioned, a flaw in the NormalizationFilter does not strip double slashes (//) from URLs, potentially enabling bypasses for XSS and access controls. An example affected URL is https://demo.dotcms.com//html/portlet/ext/files/edit_text_inc.jsp , which should return a 404 response but didn't. The oversight in the default invalid URL character list can be viewed at the provided GitHub link https://github.com/dotCMS/core/blob/master/dotCMS/src/main/java/com/dotcms/filters/NormalizationFilter.java#L37 .  To mitigate, users can block URLs with double slashes at firewalls or utilize dotCMS config variables. Specifically, they can use the DOT_URI_NORMALIZATION_FORBIDDEN_STRINGS environmental variable to add // to the list of invalid strings. Additionally, the DOT_URI_NORMALIZATION_FORBIDDEN_REGEX variable offers more detailed control, for instance, to block //html.* URLs. Fix Version:23.06+, LTS 22.03.7+, LTS 23.01.4+Show less

In dotCMS 5.x-22.06, it is possible to call the TempResource multiple times, each time requesting the dotCMS server to download a large file. If done repeatedly, this will result in Tomcat request-thread exhaustion and ultimately a denial of any other requests.Show less

In dotCMS 5.x-22.06, TempFileAPI allows a user to create a temporary file based on a passed in URL, while attempting to block any SSRF access to local IP addresses or private subnets. In resolving this URL, the TempFileAPI follows any 302 redirects that the remote URL returns. Because there is no re-validation of the redirect URL, the TempFileAPI can be used to return data from those local/private hosts that should not be accessible remotely.Show less

dotCMS before 22.06 allows remote attackers to bypass intended access control and obtain sensitive information by using a semicolon in a URL to introduce a matrix parameter. (This is also fixed in 5.3.8.12, 21.06.9, and 22.03.2 for LTS users.) Some Java application frameworks, including those used by Spring or Tomcat, allow the use of matrix parameters: these are URI parameters separated by semicolons. Through precise semicolon placement in a URI, it is possible to exploit this feature to avoid dotCMS's path-based XSS prevention (such as "require login" filters), and consequently access restricted resources. For example, an attacker could place a semicolon immediately before a / character that separates elements of a filesystem path. This could reveal file content that is ordinarily only visible to signed-in users. This issue can be chained with other exploit code to achieve XSS attacks against dotCMS.Show less

A Reflected Cross-site scripting (XSS) issue was discovered in dotCMS Core through 22.06. This occurs in the admin portal when the configuration has XSS_PROTECTION_ENABLED=false. NOTE: the vendor disputes this because the current product behavior, in effect, has XSS_PROTECTION_ENABLED=true in all configurationsShow less

An issue was discovered in the ContentResource API in dotCMS 3.0 through 22.02. Attackers can craft a multipart form request to post a file whose filename is not initially sanitized. This allows directory traversal, in which the file is saved outside of the intended storage location. If anonymous content creation is enabled, this allows an unauthenticated attacker to upload an executable file, such as a .jsp file, that can lead to remote code execution.Show less

A stored cross site scripting (XSS) vulnerability in dotAdmin/#/c/c_Images of dotCMS 21.05.1 allows authenticated attackers to execute arbitrary web scripts or HTML via a crafted payload entered into the 'Title' and 'Filename' parameters.Show less

dotCMS before 20.10.1 allows SQL injection, as demonstrated by the /api/v1/containers orderby parameter. The PaginatorOrdered classes that are used to paginate results of a REST endpoints do not sanitize the orderBy parameter and in some cases it is vulnerable to SQL injection attacks. A user must be an authenticated manager in the dotCMS system to exploit this vulnerability.Show less

DotCMS Add Template with admin panel 20.11 is affected by cross-site Scripting (XSS) to gain remote privileges. An attacker could compromise the security of a website or web application through a stored XSS attack and stealing cookies using XSS.Show less
