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.

In the System → Maintenance tool, the Logged Users tab surfaces sessionId data for all users via the Direct Web Remoting API (UserSessionAjax.getSessionList.dwr) calls. While this is information that would and should be available to admins who possess "Sign In As" powers, admins who otherwise lack this privilege would still be able to utilize the session IDs to imitate other users. While this is a very small attack vector that requires very high permissions to execute, its danger lies principally in obfuscating attribution; all Sign In As operations are attributed appropriately in the log files, and a malicious administrator could use this information to render their dealings untraceable — including those admins who have not been granted this ability — such as by using a session ID to generate an API token. Fixed in: 24.07.12 / 23.01.20 LTS / 23.10.24v13 LTS / 24.04.24v5 LTS

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-calculator

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 Failure

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+

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.

An issue was discovered in dotCMS core 4.x through 22.10.2. An authenticated directory traversal vulnerability in the dotCMS API can lead to Remote Code Execution.

An issue was discovered in dotCMS core 5.3.8.5 through 5.3.8.15 and 21.03 through 22.10.1. A cryptographically insecure random generation algorithm for password-reset token generation leads to account takeover.

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.
