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

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.

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.

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.

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.

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 configurations

CVE-2022-26352
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.
